Description

TECHNICAL FIELD

[0001] The present invention relates to a device for a valve system and to a valve system comprising such a device. BACKGROUND

[0002] FR 2 821 411 A1 describes a cartridge for mixing cold water with hot water and regulating the flow of the resulting mixed water. To regulate the flow, the cartridge comprises a flow regulating disc controlled by a flow control handle. To regulate the temperature in a hot regulated manner, the cartridge comprises a slide valve operated by a temperature control lever through a thermostat element and an overtravel compensation system. To direct the flow of water and house the various components, the cartridge comprises a housing covered by a plug, the plug itself being covered by the flow control lever, the flow control lever itself being covered by the temperature control lever. The drawback of this known cartridge is that, to circulate the water, it is necessary to provide an assembly of many parts, including the housing, the plug, the two levers, the lower disc and the upper disc, which requires a large number of seals at the interfaces of the assembly. The implementation of many seals occupies a lot of space, not only because of the seals themselves, but also because of the grooves and recesses arranged in the parts to house the seals. This leads to a relatively bulky cartridge, in particular along the central axis of the cartridge.

[0003] Generally, it is difficult to reduce the number of parts of a cartridge of this type, since each part is generally obtained by molding, so the surfaces of the parts must be undercut to be obtained by this manufacturing method. This limitation on the shape of the parts is in contradiction with the need to obtain two opposite seats facing each other along the central axis, against which the slide abuts at the end of its stroke, and with the need to obtain an inlet and an outlet to the bottom of the housing. FR 2 821 411 A1 provides a seat formed by the flow control lever and a seat formed by the upper disc, while the eccentric inlet duct and the central outlet duct are formed by the housing.

[0004] The present invention therefore aims to remedy the drawbacks of the prior art by proposing a new device designed to exchange the water flow from the bottom and having a slide valve against the distal seat and the proximal seat, in particular compact and with few assembly parts. SUMMARY

[0005] The object of the present invention is a device for a valve system, the device comprising: a housing comprising a bottom and through which the device can be coupled with a cartridge of the valve system so that the housing exchanges a water flow with the cartridge through the bottom; a spool, in order to regulate the flow rate of at least one of said water flows, the spool being able to move translationally inside the housing between a distal position, in which the spool abuts against a distal seat of the housing, and a proximal position, in which the spool abuts against a proximal seat of the housing, parallel to a longitudinal axis of the housing passing through the bottom, the proximal seat being oriented towards a distal direction parallel to the longitudinal axis, the distal seat being oriented towards a proximal direction opposite to the distal direction; and a control for the translational movement of the spool. The housing comprises: a base which houses the spool and forms the bottom of the housing, the base comprising a proximal edge having a closed profile, the proximal edge surrounding the longitudinal axis and delimiting a proximal opening of the base, the distal direction being oriented from the proximal edge towards the bottom; a spacer comprising an inner ring at least partially inserted in the proximal opening and crossed by the longitudinal axis; and a cover which houses a portion of the control, the control passing through the inner ring to move the spool.

[0006] According to the invention: the base forms the distal seat, the spacer forms the proximal seat, the proximal seat being carried by the inner ring; the cover comprises a cover fin through which the cover is pressed against the proximal edge in the distal direction; the spacer comprises a spacer fin fixedly attached to the inner ring and through which the spacer is pressed against the proximal edge in the distal direction, the cover fin and the spacer fin being consecutive along the proximal edge.

[0007] Thanks to the application, as the distal seat and the proximal seat are directly formed from parts of the housing, i.e. the base and the spacer, which are also used to guide the water flows, the housing, which accommodates the slide valve and forms the bottom for exchanging said water flows with the cartridge, is obtained with a minimum number of parts. The main function of the base is to form the bottom oriented in the distal direction and to form the distal seat oriented in the proximal direction, the base being easily obtained in the form of a single integral part, for example by molding with a single mold, in which the parts of the mold are movable with respect to each other parallel to the longitudinal axis. The main function of the cover is to close a portion of the control member, the cover can for example be given a tubular or bell-shaped shape centered on the longitudinal axis, so as to be easily obtained as a single integral part, for example by molding with a single mold, in which the parts of the mold are movable with respect to each other and parallel to the longitudinal axis. The main function of the spacer is to form the proximal seat oriented in the distal direction, to complete the base to guide at least one of the water flows, to complete the cover and to close a portion of the control member inside the cover, and optionally to form a partition wall between the inside of the base and the inside of the cover, for example by molding with a single mold, in which the parts of the mold are movable with respect to each other and parallel to the longitudinal axis, the spacer being easily obtained in the form of a single integral part. Advantageously, the housing is composed of only three assembled parts, i.e. the cover, the spacer and the base, so that the containment of the inside of the housing with respect to the outside of the housing, for example by only two seals, or in any case by a particularly small number of seals, is easily ensured. Thanks to the small number of seals, the housing is particularly compact both radially and axially. Moreover, the cover fins and the spacer fins are received resting side by side against the same proximal edge of the base, preferably in the same assembly plane orthogonal to the longitudinal axis, as the interface between the cover, the spacer and the base is within the same thickness, the housing is particularly compact.

[0008] Preferably, the inner ring comprises a distal face carrying the proximal seat and a proximal face opposite the distal face, the proximal face closing the cover, the spacer fins projecting in the proximal direction with respect to the proximal face.

[0009] Preferably, the inner ring comprises a first outer radial edge surrounding the longitudinal axis, the base comprises a first inner radial surface surrounding the longitudinal axis, the first inner radial surface terminating in the proximal direction in the proximal edge and the first inner radial surface surrounding the first outer radial edge, the spacer being inserted into the proximal opening by the radial complementarity of the first outer radial edge and the first inner radial surface, preferably by a first seal of the device radially inserted between the first outer radial edge and the first inner radial surface.

[0010] Preferably, the spacer fin comprises a first radial positioning surface; the cover comprises a second radial positioning surface, the second radial positioning surface surrounding the longitudinal axis, the cover being radially aligned with the spacer by the second radial positioning surface radially abutting the first radial positioning surface.

[0011] Preferably, the cover fin and the spacer fin radially abut each other around the longitudinal axis.

[0012] Preferably, the base comprises a first tooth, the first tooth protruding from the proximal rim, the cover fin and / or the spacer fin radially abutting the first tooth around the longitudinal axis.

[0013] Preferably, the cover fin comprises two fin legs, the two fin legs providing an inner free portion between the two fin legs, and the first tooth is received in the inner free portion to fix the base and the cover in rotation relative to each other around the longitudinal axis.

[0014] Preferably, the device comprises a fastener formed by the base and the cover, by which the base is attached to the cover so that the base is held in the distal direction relative to the cover by the fastener.

[0015] Preferably, the cover is constituted by a first integral piece, the spacer is constituted by a second integral piece, and the base is constituted by a third integral piece.

[0016] Preferably, the water flow comprises a primary flow-in water flow, a secondary flow-in water flow, and an outflow water flow. Preferably, the housing comprises a mixing chamber delimited by the base and open to the outside of the housing through a bottom for conveying the outflow water flow from the mixing chamber towards the cartridge through the bottom when the device is coupled with the cartridge seat, a main chamber delimited by the base and open to the outside of the housing through a bottom for flowing the primary flow-in water flow from the cartridge towards the main chamber through the bottom when the device is coupled with the cartridge seat, the main chamber guiding the primary flow-in water flow to the mixing chamber through a main channel provided between the distal seat and the slide valve, and a secondary chamber delimited by the base and the spacer and open to the outside of the housing through a bottom for flowing the secondary flow-in water flow from the cartridge towards the secondary chamber through the bottom when the device is coupled with the cartridge seat, the secondary chamber guiding the secondary flow-in water flow to the mixing chamber through a secondary channel provided between the proximal seat and the slide valve, the outflow water flow being formed by mixing the primary flow-in water flow and the secondary flow-in water flow within the base.

[0017] Preferably, the control comprises a thermostatic actuator comprising: a primary piece at least partially housed in the base to be immersed in one of said water flows, the spool and the primary piece being preferably fixed in translation with respect to each other along the longitudinal axis; and a secondary piece at least partially housed in the cap and which moves in translation along the longitudinal axis with respect to the primary piece as a function of the temperature of the water flow in which the primary piece is immersed. Preferably, the control comprises a control member at least partially housed in the cap and configured to move the spool in translation along the longitudinal axis with respect to the housing by displacing the secondary piece.

[0018] The present application also relates to a valve system comprising a device as defined above and a cartridge, the device being coupled with the cartridge through the base so that the housing exchanges said water flow with the cartridge through the base. BRIEF DESCRIPTION OF DRAWINGS

[0030] A device 1 according to a first embodiment of the application is shown. This device 1 is preferably intended for sanitary use, connected to a sanitary water network, for example for a residential or professional site. Figures 1 to 6 The device 1 is here presented in the form of a sleeve, preferably intended for mixing a primary incoming water flow F1 and a secondary incoming water flow F2 to form an outgoing water flow F3. The device 1 for connection to a sanitary water system is configured to be coupled with a cartridge 60, a portion of which is shown in dotted lines in

[0031] and Figure 5 , the cartridge forming with the device a valve system. The valve system is preferably constituted by a system mounted on a wall, the cartridge 60 being arranged to be partially embedded in the wall, or more generally in a masonry wall, regardless of the orientation of the cartridge. The valve system is preferably a mixer for a shower or a bath, the cartridge 60 being designed to supply for example a shower head, a rain shower head and / or a bath jet. Alternatively, the cartridge 60 forms a cartridge of a sink or washbasin faucet, the faucet also comprising a washbasin jet. In this case, for example, the cartridge is intended to be mounted in a sink vanity or countertop, in a rear splashback panel close to the vanity or countertop, or in the sink or washbasin itself. Figure 6

[0032] and Figure 5 The device 1 is shown, comprising a housing 10, a slide valve 2 housed in the housing 10, and a control member 3 housed at least partially in the housing 10. The device defines a longitudinal axis X1 fixed with respect to the housing 10. Unless otherwise specified, terms such as "radial", "axial", "coaxial", "center", "longitudinal" and "transverse" refer to the longitudinal axis X1. Figure 6 and Figure 5 the cross sections in Figure 6 along two different planes including the longitudinal axis X1.

[0033] The device 1 also defines a distal direction X11 parallel to the longitudinal axis X1 and a proximal direction X12 parallel to the longitudinal axis X1 and opposite in direction to the distal direction X11. Unless otherwise stated, when the term "distal" is used, the distal refers to the distal direction X11 and when the term "proximal" is used, the proximal refers to the proximal direction X12.

[0034] As shown in Figures 1 to 6 The housing 10 consists of only three components, namely the cover 12, the spacer 13 and the base 11, which are stacked one after the other in the distal direction X11. These three components are different from each other. The cover 12 is preferably formed as a one-piece, in other words the cover is integral and not the result of an assembly. The base 11 is preferably formed as a one-piece, in other words the base is integral and not the result of an assembly. The spacer 13 is preferably formed as a one-piece, in other words the spacer is integral and not the result of an assembly. Each of these three components advantageously has a respective shape which makes it possible to manufacture the components separately in a single molding operation, for example by injection of a polymer plastic, in a single mold. For each component, a first part of the mold is advantageously displaced relative to a second part of the mold along the longitudinal axis X1. The housing 10 is designed as a seat for the passage of water flows, here the primary inflow water flow F1, the secondary inflow water flow F2 and the outflow water flow F3, which exchange between the housing 10 and the cartridge seat 60 when the device is coupled on said cartridge seat 60.

[0035] Preferably, the housing 10 has a general shape which rotates around the longitudinal axis X1 on the outside. The housing 10 defines a proximal end formed by the cover 12 and a distal end formed by the base 11, the distal end and the proximal end being crossed by the longitudinal axis X1. The housing 10 comprises an outer peripheral wall which connects the distal end of the housing to the proximal end of the housing, surrounding the longitudinal axis X1. From the distal end, the peripheral wall of the housing 10 is formed by the first peripheral wall 16 of the base 11. From the proximal end, the peripheral wall of the housing 10 is formed by the second peripheral wall 17 of the cover 12.

[0036] At the distal end of the housing, the housing 10 comprises a bottom 18. The bottom 18 is crossed by the longitudinal axis X1. The bottom 18 is entirely formed by the base 11, which is formed in one piece with the first peripheral wall 16. For the exchange of the primary inflow water flow F1, the secondary inflow water flow F2 and the outflow water flow F3 with the cartridge seat 60, the device 1 is coupled with the cartridge seat 60 by the bottom 18, which is received by the cartridge seat 60 in a manner parallel to the longitudinal axis X1. The exchange of the primary inflow water flow F1, the secondary inflow water flow F2 and the outflow water flow F3 then takes place through the bottom 18, in other words the primary inflow water flow F1, the secondary inflow water flow F2 and the outflow water flow F3 pass through the bottom 18.

[0037] Preferably, the housing 10 has a control opening 19 at a proximal end of the housing. The control opening 19 is coaxial with the longitudinal axis X1. The control opening 19 is delimited by the second peripheral wall 17. Through the control opening 19, the control member 3 can be operated from the outside of the device 1.

[0038] On the inside, the housing 10 comprises an inner ring 20, which is entirely formed by the spacer 13. The inner ring 20 extends preferably along an inner ring plane P20 perpendicular to the longitudinal axis X1. The inner ring 20 is arranged between the control opening 19 and the bottom 18. The inner ring 20 is crossed by the longitudinal axis X1. The inner ring 20 provides a first central opening 21 coaxial with the longitudinal axis X1, so that the inner ring 20 can be described as an inner shoulder of the housing 10. The first central opening 21 is preferably of moderate size with respect to the cross-section of the first peripheral wall 16 and of the second peripheral wall 17.

[0039] In the present example, the inner ring 20 occupies a lateral cross-section of the housing 10, which divides the housing 10 into a distal compartment 15 delimited by the base 11 and the spacer 13, and a proximal compartment 14 delimited by the cover 12 and the spacer 13. In other words, along the longitudinal axis X1, the inner ring 20 is arranged at the junction between the base 11 and the cover 12. The proximal compartment 14 and the distal compartment 15 are distributed in succession along the longitudinal axis X1, the distal compartment 15 being arranged in the distal direction X11 with respect to the proximal compartment 14. The first central opening 21 opens onto the proximal compartment 14 in the proximal direction X12 and onto the distal compartment 15 in the distal direction X11.

[0040] In the present example, the distal compartment 15 can be called a “mixing compartment”, since it houses the slide valve 2. More generally, the distal compartment 15 is a seat for the flow control of all or part of the primary incoming water flow F1, of the secondary incoming water flow F2 and of the outgoing water flow F3 by the slide valve 2. To this end, the slide valve 2 can be moved translationally with respect to the housing 10 along the longitudinal axis X1 within the base 11, in other words within the distal compartment 15.

[0041] The proximal compartment 14 can be called a “control compartment”, since a part of the control member 3 is housed in this proximal compartment. The function of the control member 3 is to actuate the translation of the slide valve 2, in order to adjust the flow rate of the primary incoming water flow F1, of the secondary incoming water flow F2 and / or of the outgoing water flow F3. To this end, the control member 3 extends through the first central opening 21 into the proximal compartment 14 and into the distal compartment 15 at the same time.

[0042] The first circumferential wall 16 of the base 11 is preferably of tubular shape, surrounding and centered on the longitudinal axis X1. The first circumferential wall 16 is preferably in the form of a circular-based cylinder centered on the longitudinal axis X1, or in the form of a succession of circular-based cylinders distributed along the longitudinal axis X1. For example, as illustrated in Figure 1 , Figure 3 and Figure 4 , the shape of the first circumferential wall 16 is like that of two successive cylinders.

[0043] In the proximal direction X12, the first circumferential wall 16 ends at a proximal edge 34. The proximal edge 34 describes a closed profile around the longitudinal axis X1, centered on the longitudinal axis X1. Preferably, the proximal edge 34 is flat and forms a coronal surface surrounding the longitudinal axis X1. The proximal edge 34 extends along an assembly plane P34 of the housing 10, perpendicular to the longitudinal axis X1. The assembly plane P34 is arranged in the proximal direction X12 relative to the inner ring plane P20. From the proximal edge 34, the first circumferential wall 16 forms, internally, a first inner radial surface 36 of the base 11. The first inner radial surface 36 surrounds the longitudinal axis X1 by being coaxial with this longitudinal axis. In the proximal direction X12, the first inner radial surface 36 extends to the inner profile of the proximal edge 34. In other words, the first inner radial surface 36 ends at the proximal edge 34.

[0044] The first circumferential wall 16, in particular the proximal edge 34 and the first inner radial surface 36, delimit a proximal opening 35 of the base 11 by surrounding the proximal opening of the base. The proximal opening 35 opens in the proximal direction X12. In the present example, the function of the spacer 13 is to close the proximal opening 35 of the base 11 with the inner ring 20 by attaching to the base 11. Here, the inner ring 20 has the function of an inner partition.

[0045] More precisely, on either side of the inner ring plane P20, the inner ring 20 advantageously comprises a distal face 22 facing the interior of the base 11 in the distal direction X11 and a proximal face 23 facing the interior of the cover 12 in the proximal direction X12. The proximal face 23 is thus axially opposite the distal face 22. Preferably, the distal face 22 and the proximal face 23 have a substantially discoid or coronal shape centered on the longitudinal axis X1. The first central opening 21 opens from the distal face 22 in the distal direction X11 and from the proximal face 23 in the proximal direction X12. The inner ring 20 also comprises a first outer radial edge 24 surrounding the longitudinal axis X1 and connecting the distal face 22 to the proximal face 23.

[0046] The inner ring 20 is preferably received in the base 11, preferably by insertion in the proximal opening 35 along the longitudinal axis X1 in a press-fit manner. Preferably, the inner ring 20 occupies most of the transverse section of the proximal opening 35, or even completely closes the proximal opening 35 at the first central opening 21, like an internal bulkhead. More precisely, the press-fit is achieved by radial complementarity of the first outer radial edge 24 with the first inner radial surface 36. The first inner radial surface 36 of the base 11 surrounds the first outer radial edge 24 of the inner ring 20, so that the first outer radial edge 24 is in radial contact with the first inner radial surface 36, or at least a small clearance is provided which enables the inner ring 20 to be fitted into the base 11. Preferably, the device 1 comprises a first seal 25, here an O-ring, which is inserted radially between the first outer radial edge 24 and the first inner radial surface 36 to ensure the seal between the outside and the inside of the distal compartment 15 at the proximal opening 35. In this case, the inner ring 20 can be fitted into the base 11 by the first seal 25 which is inserted radially between the first outer radial edge 24 and the first inner radial surface 36. Preferably, the first seal 25 is carried by a circumferential groove formed on the first outer radial edge 24.

[0047] As shown in Figures 1 to 6 The spacer 13 comprises a plurality of fins, each of which is referred to as a spacer fin 26. Here, for example, four spacer fins 26 are provided, however a different number of spacer fins 26 can be provided. At least, the spacer 13 comprises a single spacer fin 26.

[0048] Each spacer fin 26 is preferably formed integrally with the inner ring 20. More generally, each spacer fin 26 is fixed integrally with the inner ring 20, in other words each spacer fin is fixed relative to the inner ring 20 by attachment to the inner ring.

[0049] Each spacer fin 26 axially projects from the inner ring 20 in the proximal direction X12 relative to the proximal face 23 of the inner ring 20. In other words, each spacer fin 26 extends from the assembly plane P34 in the proximal direction X12, whereas the inner ring 20 extends from the assembly plane P34 in the distal direction X11. More generally, each spacer fin 26 is arranged entirely in the proximal direction X12 relative to the inner ring plane P20, or even relative to the inner ring 20.

[0050] Each spacer fin 26 extends along the first outer radial edge 24 of the inner ring 20. In other words, the spacer fin 26 is a circumferential element of the spacer 13. Each spacer fin 26 radially protrudes, in other words, in an outward radial direction, from the first outer radial edge 24. In other words, each spacer fin 26 overhangs the first outer radial edge 24. Around the longitudinal axis X1, each spacer fin 26 extends only over a portion of the first outer radial edge 24, leaving a portion of the proximal face 23 free along the first outer radial edge 24. If a plurality of spacer fins 26 is provided, the plurality of spacer fins are spaced apart from each other around the longitudinal axis X1 along the first outer radial edge 24, so that two consecutive spacer fins 26 leave a portion of the proximal face 23 free between them along the first outer radial edge 24 around the longitudinal axis X1. Preferably, the spacer fins 26 are uniformly distributed around the longitudinal axis X1, so that the free portions between the spacer fins are uniformly distributed around the longitudinal axis X1.

[0051] By abutting each spacer fin 26 against the proximal edge 34, the spacer 13 is held against the base 11 in the distal direction X11. More precisely, each spacer fin 26 has a first distal surface 27 which axially abuts against the proximal edge 34. To this end, the first distal surface 27 extends along an assembly plane P34, as shown in Figure 5 and Figure 6 In other words, the first distal surface 27 is parallel to the inner ring 20, i.e. perpendicular to the longitudinal axis X1. The first distal surface 27 extends radially outwardly from the first outer radial edge 24, thereby forming an axial shoulder of the spacer 13. Here, the first distal surface 27 forms part of a crown centered on the longitudinal axis X1. The first distal surface 27 is offset in the proximal direction X12 relative to the inner ring plane P20, in other words, relative to the inner ring 20, so that when the spacer 13 is held against the proximal edge 34, the inner ring 20 is arranged at least partially beyond the proximal edge 34 in the distal direction X11. Each spacer fin 26 occupies as much of the proximal edge 34 as possible by pressing on the proximal edge 34, but leaves other portions of the proximal edge 34 free, in particular between two consecutive spacer fins 26 which are not pressed by a spacer fin 26.

[0052] The assembly formed by the spacer 13 and the base 11 is thus particularly compact along the longitudinal axis X1. Moreover, the assembly of the spacer 13 on the base 11 is particularly easy to carry out, since it is sufficient to slide the inner ring 20 of the spacer 13 into the proximal opening 35 of the base 11 to align the spacer 13 with the base 11, and to slide the spacer 13 in the distal direction X11 until the spacer fins 26 axially abut against the proximal edge 34.

[0053] In the distal direction X11, the first peripheral wall 16 terminates at the bottom 18 of the receptacle 10. In other words, the first peripheral wall 16 axially connects the inner ring 20 to the bottom 18 to delimit the distal compartment 15. Thus, the distal direction X11 is oriented from the proximal edge 34 towards the bottom 18. Preferably, the bottom 18 has the form of a transverse wall, perpendicular to the longitudinal axis X1 and crossed by the longitudinal axis X1.

[0054] Preferably, when the receptacle 10 is coupled to the cartridge seat 60, the base 11 is at least partially received in a recess 64 belonging to the cartridge seat 60, the base 11 and the recess 64 being complementary and indexed. The receptacle 10 is inserted into the recess 64 in the distal direction X11. The recess 64 is schematically shown in dashed lines in Figure 5 and Figure 6 . The base 11 forms a male part, while the recess 64 of the cartridge seat 60 forms a complementary female part. The recess 64 is advantageously closed by the base 11 when the device 1 is coupled with the cartridge seat 60.

[0055] The recess 64 of the cartridge seat 60 advantageously has an inner peripheral wall 61 which surrounds the axis of the recess, coaxial with the longitudinal axis X1 when the device 1 is coupled. This inner peripheral wall 61 surrounds a portion of the base 11 extending from the bottom 18. In particular, this inner peripheral wall 61 surrounds a portion of the first peripheral wall 16, this portion of the wall being inserted into the inner peripheral wall 61, preferably by being pressed into the inner peripheral wall 61. Advantageously, the device 1 comprises a circumferential seal 37, such as an O-ring, of circular shape, centered on the longitudinal axis X1. The circumferential seal 37 is here carried by the base 11, in particular by the first peripheral wall 16. To this end, the base 11 is provided, on the outer surface of the first peripheral wall 16, with for example a circumferential groove to accommodate said circumferential seal 37. When the receptacle 10 is coupled to the cartridge seat 60, the circumferential seal 37 is in radial contact with the inner peripheral wall 61 of the recess 64 to ensure the watertightness of the closure of the base 11 to the recess 64, as Figure 5 and Figure 6 illustrated.

[0056] Advantageously, the recess 64 of the cartridge seat 60 has a transverse bottom wall 62 which closes the inner peripheral wall 61. The bottom wall 62 is crossed by the longitudinal axis X1, preferably orthogonally to the longitudinal axis X1, when the receptacle 10 is coupled. The device advantageously abuts against the bottom wall 62 in the distal direction X11 by the bottom 18 when the receptacle 10 is coupled.

[0057] In the present example, the primary incoming water flow F1 and the secondary incoming water flow F2 are incoming water flows into the housing 10 via the bottom 18, the primary incoming water flow F1 and the secondary incoming water flow F2 coming from the cartridge 60 when the housing 10 is coupled with the cartridge 60. The primary incoming water flow F1 is referred to as the “primary incoming water flow” and the secondary incoming water flow F2 is referred to as the “secondary incoming water flow”. The primary incoming water flow F1 and the secondary incoming water flow F2 are advantageously water flows from a sanitary water network of the supply cartridge 60. For example, the primary incoming water flow F1 passes through a primary inlet opening 41 provided through the bottom 18, in particular as shown in Figure 1 and Figure 5 For example, the secondary incoming water flow F2 passes through a secondary inlet opening 42 provided through the bottom 18, in particular as shown in Figure 1 and Figure 6 For example, the secondary incoming water flow F2 passes through a secondary inlet opening 42 provided through the bottom 18, in particular as shown in

[0058] In the present example, the outgoing water flow F3 is an outgoing water flow that, when the housing 10 is coupled with the cartridge 60, exits the housing 10 via the bottom 18 and is delivered to the cartridge 60. Advantageously, the outgoing water flow F3 is used to supply a valve spout or a shower head of a valve system. For example, the outgoing water flow F3 passes through an outlet opening 43 provided through the bottom 18.

[0059] More precisely, by the primary inlet opening 41, the secondary inlet opening 42 and / or the outlet opening 43 of the bottom 18, the housing 10, when coupled, is pressed against the bottom wall 62 along the longitudinal axis XI, in particular to ensure a seal of the fluidic connection between the cartridge 60 and the device 1 to exchange the primary incoming water flow F1, the secondary incoming water flow F2 and the outgoing water flow F3.

[0060] In the present example, the cartridge 60 has two openings out of the bottom wall 62, one to exit the primary incoming water flow F1 to feed the primary inlet opening 41 and the other to exit the secondary incoming water flow F2 to feed the secondary inlet opening 42. To ensure the fluidic connection between the primary inlet opening 41 and the corresponding opening in the cartridge 60, and the fluidic connection between the secondary inlet opening 42 and the corresponding opening in the cartridge 60, the housing 10 is pressed against these openings in the cartridge 60 by the primary inlet opening 41 and the secondary inlet opening 42 in the distal direction XI 1. Preferably, the outlet opening 43 directly opens into the recess 64 so that the outgoing water flow F3 fills the recess 64.

[0061] Only as shown in Figure 5 Advantageously, the bottom 18 carries a second seal 46 that surrounds the primary inlet opening 41 to ensure the seal of the fluidic connection between the primary inlet opening 41 and the corresponding opening of the cartridge 60 with respect to the recess 64 and the outlet opening 43. Only as shown in Figure 6As shown, advantageously, the bottom 18 carries a third seal 47 surrounding the secondary inlet opening 42 for sealing the fluid connection between the secondary inlet opening 42 and the corresponding opening of the cartridge seat 60 with respect to the recess 64 and the outlet opening 43. Each second seal 46 and each third seal 47 is preferably housed in a respective circular groove made in the surface of the bottom 18 around the relevant primary inlet opening 41 or secondary inlet opening 42, as shown in Figure 1 , Figure 5 and Figure 6 .

[0062] Preferably, as Figure 1 , Figure 5 and Figure 6 best seen, the base 11 comprises a first plug 44 and a second plug 45, in other words, a stem, which projects from the bottom 18 in the distal direction X11 and which cooperates with a complementary guide belonging to the cartridge seat 60, which leads to the recess 64. The first plug 44 and the second plug 45, inserted into the guide, constitute an encoding method which ensures that the positioning of the device 1 in the recess 64 is correct for the coupling of the bottom with the recess 64, in particular for the orientation of the receptacle 10 around the longitudinal axis X1 with respect to the cartridge seat 60. This ensures that the primary inlet opening 41, the secondary inlet opening 42 and the outlet opening 43 are correctly positioned for the fluid connection of the openings with the cartridge seat 60. Alternatively, instead of the first plug 44 and the second plug 45, a single plug can be provided, or a plurality of plugs other than two, or any other anti-rotation form of the base 11 in the cartridge seat 60.

[0063] In the present example, the spool 2 and the distal compartment 15, i.e. the mixing compartment, together form a mixer which is configured to form an outgoing water flow F3 by mixing the primary incoming water flow Fl and the secondary incoming water flow F2 entering the receptacle 10 when the receptacle 10 is coupled with the cartridge seat 60. Preferably, the device 1 is designed so that the primary incoming water flow Fl is a hot water flow and the secondary incoming water flow F2 is a cold water flow. By "cold water" is meant unheated mains water, which is usually at or slightly below ambient temperature. By "hot water" is meant mains water which has been heated by a sanitary heating system. More generally, hot water has a higher temperature than cold water. The outgoing water flow F3 resulting from the mixing of the primary incoming water flow Fl and the secondary incoming water flow F2 by the mixer is therefore at an intermediate temperature between the temperatures of the primary incoming water flow Fl and the secondary incoming water flow F2, which depends on the proportions of the mixture of the primary incoming water flow Fl and the secondary incoming water flow F2. The outgoing water flow F3 can be called a mixed water flow and the device 1 can be called a mixing device.

[0064] The housing 10 comprises a main chamber 31 or inlet chamber for guiding a main incoming water flow Fl within the housing 10 from the cartridge seat 60 to the spool valve 2. The main chamber 31 opens through a main inlet opening 41 outside the housing 10 for the entry of the main incoming water flow Fl. The housing 10 comprises a secondary chamber 32 or inlet chamber for guiding a secondary incoming water flow F2 within the housing 10 from the cartridge seat 60 to the spool valve 2. The secondary chamber 32 opens through a secondary inlet opening 42 outside the housing 10 for the entry of the secondary incoming water flow F2. The housing 10 comprises a mixing chamber 33 or outlet chamber for guiding an outgoing water flow F3 within the housing 10 from the spool valve 2 to the cartridge seat 60. The mixing chamber 33 opens through an outlet opening 43 outside the housing 10 for the exit of the outgoing water flow F3. The main chamber 31, the secondary chamber 32 and the mixing chamber 33 together constitute the distal compartment 15 and are all arranged within the base 11.

[0065] In the distal compartment 15, the housing 10 comprises a distal seat 38 and a proximal seat 39. The distal seat 38 is formed by a surface of the housing 10 facing the proximal direction X12, in other words perpendicular to the longitudinal axis X1, preferably this surface is flat. The proximal seat 39 is formed by a surface of the housing 10 facing the distal direction X11, in other words perpendicular to the longitudinal axis X1, preferably this surface is flat. The distal seat 38 is arranged in the distal direction X11 relative to the proximal seat 39. Preferably, the distal seat 38 and the proximal seat 39 are arranged facing each other. In particular, the distal seat 38 and the proximal seat 39 are both crossed by the longitudinal axis X1. Advantageously, the distal seat 38 and the proximal seat 39 are perpendicular to the displacement axis of the spool valve 2. The distal seat 38 and the proximal seat 39 have for example a discoid or a crown shape centered on the longitudinal axis X1.

[0066] The spool valve 2 is arranged between the distal seat 38 and the proximal seat 39, centered on the longitudinal axis X1. The spool valve 2 has a distal side 48 facing the distal direction X11 and a proximal side 49 facing the proximal direction X12. The distal side 48 and the proximal side 49 are preferably centered on the longitudinal axis X1.

[0067] In Figure 5 and Figure 6 , the spool valve 2 is shown in an intermediate position between two end positions of the translational stroke of the spool valve, respectively called "distal position" and "proximal position". In Figure 5 and Figure 6In the intermediate position illustrated, the spool 2 is located between the distal seat 38 and the proximal seat 39, so that the distal lateral face 48 is not in contact with the distal seat 38 and the proximal lateral face 49 is not in contact with the proximal seat 39. The displacement of the spool 2 in translation relative to the housing 10 is limited by the distal seat 38 and the proximal seat 39, the spool 2 alternately axially abutting against the distal seat 38 and the proximal seat 39. The spool 2 is axially pressed against the distal seat 38 by the distal lateral face 48 in the distal direction X11 to limit the translational movement of the spool 2 in the distal direction X11. Thus, when pressed against the distal seat 38, the spool 2 is in the distal position. On the other hand, the spool 2 is axially held against the proximal seat 39 by the proximal lateral face 49 in the proximal direction X12 to limit the translational movement of the spool 2 in the proximal direction X12. Thus, when pressed against the proximal seat 39, the spool 2 is in the proximal position. In the present example, the annular-shaped surface of the distal lateral face 48 centered on the longitudinal axis X1 is in contact with the corresponding surface of the distal seat 38. In the present example, the crown-shaped surface of the proximal lateral face 49 centered on the longitudinal axis X1 is in contact with the corresponding surface of the proximal seat 39.

[0068] The distal seat 38 and the distal lateral face 48 of the spool 2 provide a passage between them, called the "primary passage 50", the opening of which varies depending on the translational position of the spool 2. When the spool 2 is in the distal position, the primary passage 50 is preferably closed or almost closed by the spool 2 pressed against the distal seat 38, whereas when the spool 2 is in the proximal position, the primary passage 50 is opened to a maximum since the spool 2 is distanced from the distal seat 38. Preferably, the primary passage 50 is annular-shaped and is provided to extend axially from the distal seat 38 to the distal lateral face 48 of the spool 2, entirely surrounding the longitudinal axis X1. The primary passage 50 is intended to be crossed by the primary incoming water flow Fl.

[0069] The proximal seat 39 and the proximal lateral face 49 of the spool 2 provide a passage between them, called the "secondary passage 51", the opening of which varies depending on the translational position of the spool 2. When the spool 2 is in the proximal position, the secondary passage 51 is preferably closed or almost closed by the spool 2 pressed against the proximal seat 39, whereas when the spool 2 is in the distal position, the secondary passage 51 is opened to a maximum since the spool 2 is distanced from the proximal seat 39. Preferably, the secondary passage 51 is annular-shaped and is provided to extend axially from the proximal seat 39 to the proximal lateral face 49 of the spool 2, entirely surrounding the longitudinal axis X1. Preferably, the secondary passage 51 is arranged in the proximal direction X12 relative to the primary passage 50. The secondary passage 51 is intended to be crossed by the secondary incoming water flow F2.

[0070] In general, as Figure 5 and Figure 6As illustrated, the primary chamber 31, the secondary chamber 32 and the mixing chamber 33 are preferably coaxial, which makes it possible for the base 11 to have good compactness. This arrangement also makes it easier to obtain the base 11 by moulding, since most of the walls of the base 11, apart from the bottom 18, are oriented parallel to the longitudinal axis X1. Thus, the walls of the base 11 are not undercut along the longitudinal axis X1.

[0071] In particular, in the present example, the mixing chamber 33 is crossed by the longitudinal axis X1 and connects the primary channel 50 and the secondary channel 51 to the outlet opening 43. The receptacle 10, in this case the base 11, preferably comprises a first annular wall 53 which surrounds the longitudinal axis X1 and is surrounded by the first peripheral wall 16. The first annular wall 53 rises from the bottom 18 in the proximal direction X12 and terminates in a coronal edge centred on the longitudinal axis X1 which forms the distal seat 38. The first annular wall 53 delimits the mixing chamber 33 radially on the outside. The mixing chamber 33 terminates axially at the bottom 18 in the distal direction X11. The mixing chamber 33 terminates axially at the distal seat 38 in the proximal direction X12.

[0072] Preferably, the primary chamber 31 surrounds the mixing chamber 33, which has an annular shape centred on the longitudinal axis X1. The primary chamber 31 is separated from the mixing chamber 33 by the first annular wall 53. In other words, the first annular wall 53 delimits the primary chamber 31 radially on the inside. The receptacle 10, in this case the base 11, preferably comprises a second annular wall 54 which surrounds the first annular wall 53 and the longitudinal axis X1. The second annular wall 54 rises from the bottom 18 in the proximal direction X12 and terminates in an annular edge which is axially spaced apart from the inner ring 20. The second annular wall 54 is arranged radially between the first peripheral wall 16 and the first annular wall 53. The second annular wall 54 delimits the primary chamber 31 radially on the outside and surrounds it. In the distal direction X11, the primary chamber 31 is preferably delimited by the bottom 18.

[0073] Preferably, the primary chamber 31 is itself surrounded by the secondary chamber 32, which has an annular shape centred on the longitudinal axis X1. The secondary chamber 32 is delimited radially on the inside by the second annular wall 54 and radially on the outside by the first peripheral wall 16. In the distal direction X11, the secondary chamber 32 is preferably delimited by the bottom 18. In the proximal direction X12, the secondary chamber 32 is preferably delimited by the inner ring 20, in particular by the distal face 22. Thus, the delimitation of the distal compartment 15 by the receptacle 10 is achieved by the base 11 and the spacer 13.

[0074] The spacer 13 is also intended to form a proximal seat 39. In particular, the proximal seat 39 is formed on the distal face 22 of the inner ring 20, preferably this proximal seat projects in the distal direction X11. By providing the proximal seat 39 formed by the spacer 13 and the distal seat 38 formed by the base 11, it is possible to obtain an entire distal compartment 15 which is delimited only by the two integral pieces of the assembly of the containment 10, namely the base 11 and the spacer 13. Therefore, each of these two pieces can have a shape which makes it possible for the two pieces to be obtained by separate moulding as described above.

[0075] As Figure 5 As is clear from

[0076] The secondary chamber 32 opens into the mixing chamber 33 through a secondary channel 51, preferably through the spool valve 2 (axially through the secondary chamber) to the mixing chamber. To this end, the spool valve 2 advantageously comprises one or more axial openings 52, two of which are visible in Figure 5 Each axial opening 52 passes through the spool valve 2 from one side to the other along the longitudinal axis X1, to connect the proximal side 49 to the distal side 48. The outlet of each axial opening 52 on the distal side 48 extends radially between the main channel 50 and the longitudinal axis X1, in other words between the distal seat 38 and the longitudinal axis X1. In other words, each axial opening 52 opens downstream of the main channel 50, considering the direction of flow of the main incoming water flow Fl. Each axial opening 52 opens into the mixing chamber 33 and not into the main chamber 31. The outlet of each axial opening 52 on the proximal side 49 extends radially between the secondary channel 51 and the longitudinal axis X1, in other words, considering the direction of flow of the secondary incoming water flow F2, this outlet extends downstream of the secondary channel 51.

[0077] Therefore, the secondary chamber 32 directs the secondary incoming water flow F2 from the secondary inlet opening 42 to the mixing chamber 33 through the secondary channel 51, so that when the secondary incoming water flow F2 passes through the secondary channel 51, the flow rate of this flow is regulated according to the degree of opening of said secondary channel 51 determined by the position of the spool valve 2.

[0078] More generally, it is advantageous for the secondary incoming water flow F2 from the secondary chamber 32 to pass through the spool valve 2 to reach the mixing chamber 33, while the main incoming water flow Fl from the main chamber 31 reaches the mixing chamber 33 directly without passing through the spool valve 2.

[0079] Advantageously, it can be envisaged that the spool valve 2 fluidically separates the primary chamber 31 and the secondary chamber 32. In Figure 5 and Figure 6 In the case illustrated, the spool valve 2 is received at the proximal end of the second annular wall 54 to close the proximal opening defined by this second annular wall 54. In other words, for any position of the spool valve 2 along its translation stroke, the spool valve 2 is at least partially axially inserted into the tubular shape of the second annular wall 54. In particular, the spool valve 2 comprises a second outer radial edge 55 which surrounds the longitudinal axis X1 by being centered on this longitudinal axis X1 and is surrounded by the second annular wall 54 in the vicinity of the proximal end of this second annular wall 54. Preferably, the second outer radial edge 55 is carried by a ring of the spool valve 2 which axially connects the distal side 48 to the proximal side 49. Preferably, the device 1 comprises a fourth seal 56 which is radially inserted between the second outer radial edge 55 and the second annular wall 54 to ensure the sealing between the primary chamber 31 and the secondary chamber 32. The fourth seal 56 is for example in the form of an O-ring which is received in a circumferential groove formed in the surface of the second outer radial edge 55.

[0080] In summary, the primary chamber 31 and the mixing chamber 33 are entirely delimited by the base 11, while the secondary chamber 32 is entirely formed by the base 11 and the inner ring 20 of the spacer 13, preferably the secondary chamber 32 is sealed by the first seal 25.

[0081] The second circumferential wall 17 of the cover 12 is preferably tubular or bell-shaped, surrounding and centered on the longitudinal axis X1. The second circumferential wall 17 is preferably in the form of a succession of circular-based cylinders centered on and distributed along the longitudinal axis X1. For example, as illustrated in Figure 1 , Figure 3 and Figure 4 The second circumferential wall 17 has the shape of two consecutive cylinders, one of which is optionally slotted on the outside.

[0082] In the proximal direction X12, the second circumferential wall 17 ends with a proximal edge which describes a closed profile centered on the longitudinal axis X1 to internally delimit the control opening 19, this proximal edge having a circular shape centered on the longitudinal axis X1.

[0083] In the distal direction X11, the second circumferential wall 17 terminates in a distal edge 71. The distal edge 71 describes a closed profile around the longitudinal axis X1, this closed profile being centred on the longitudinal axis X1. Preferably, the distal edge 71 is flat and forms a surface of a coronal shape surrounding the longitudinal axis X1. The distal edge 71 preferably extends along the assembly plane P34, or between the assembly plane P34 and the inner ring plane P20. The second circumferential wall 17 extends from the distal edge 71 in the proximal direction X12.

[0084] The second circumferential wall 17, and in particular the distal edge 71, delimits a distal opening 72 of the cover 12 by surrounding the distal opening of the cover. The distal opening 72 opens in the distal direction X11. The second circumferential wall 17 extends from the distal opening 72, in other words from the distal edge 71, to the control opening 19 to axially connect the distal opening and the control opening. The proximal compartment 14 radially delimited by the second circumferential wall 17 connects the distal opening 72 to the control opening 19 to open from the cover 12 in the distal direction X11, and in other words to open from the cover 12 in the proximal direction X12.

[0085] In the present example, the function of the spacer 13 is to close the proximal compartment 14, in other words the cover 12, in the distal direction X11. This closure is not necessarily watertight, in particular if the primary incoming water flow F1, the secondary incoming water flow F2 and the outgoing water flow F3 are confined in the distal compartment 15, as is the case in this example. More generally, the cover 12 is fitted axially against the spacer 13, in particular pressed against the spacer 13 in the distal direction X11. It can be provided that the distal edge 71 of the cover 12 is pressed against the proximal face 23 of the inner ring 20, as illustrated in Figure 5 and Figure 6 as illustrated, in particular against the circular rib 73 formed on the surface of the proximal face 23, visible in particular in Figure 4 , Figure 5 and Figure 6 . Alternatively, it can be provided that the distal edge 71 is not pressed against the spacer 13 in the distal direction X11, but is for example axially distant from the proximal face 23.

[0086] Externally, the second circumferential wall 17 of the cover 12 forms an outer radial surface, referred to as a second radial positioning surface 74. This second radial positioning surface 74 is centred on the longitudinal axis X1 and preferably exhibits a cylindrical shape with a circular base.

[0087] Preferably, each spacer fin 26 has an inner radial surface, referred to as a first radial positioning surface 28. This first radial positioning surface 28 extends axially from the proximal face 23 of the inner ring 20. This first radial positioning surface 28 extends radially away from the longitudinal axis X1, radially inwards, in other words, facing the longitudinal axis X1. This first radial positioning surface 28 preferably has a geometry in the form of a portion of a cylinder comprising a circular base, this cylinder being centred on the longitudinal axis X1.

[0088] More generally, the first radial positioning surface 28 of the spacer fin 26 and the second radial positioning surface 74 of the cover 12 have complementary shapes to be able to press radially against each other. Thus, the first radial positioning surface 28 and the second radial positioning surface 74 can be referred to as radial positioning surfaces. Indeed, by pressing the second peripheral wall 17 of the cover 12 into fit reception on the inner side of the spacer fin 26, in other words, by radial fit of the first radial positioning surface 28 and the second radial positioning surface 74, the cover 12 and the spacer 13 are coaxially positioned. In other words, the spacer fin 26 delimits a portion of an opening, in the present example, this opening is cylindrical in shape, with a circular base centred on the longitudinal axis X1, for reception of the cover 12 by the second peripheral wall 17. It can be provided that this opening, the portion of which is delimited by the spacer fin 26, has any other suitable shape complementary to that of the second peripheral wall 17 of the cover 12, for example conical. Each spacer fin 26 holds the cover 12 radially externally, to keep the cover centred. Thus, the spacer fin 26 ensures the alignment of the cover 12 and the spacer 13, in other words, the relative radial positioning of the cover and the spacer.

[0089] As Figures 1 to 4 illustrated, the cover 12 comprises a plurality of fins, each fin being referred to as a cover fin 75. Each cover fin 75 is preferably formed integrally with the second peripheral wall 17. More generally, each cover fin 75 is fixed integrally with the second peripheral wall 17, in other words, each cover fin is fixed relative to the second peripheral wall 17 by attachment to the second peripheral wall 17.

[0090] Each cover fin 75 projects radially outwards from the second peripheral wall 17, more particularly from the second radial positioning surface 74. In other words, the cover fin 75 is a peripheral element of the cover 12.

[0091] Around the longitudinal axis X1, each cover fin 75 extends only over a portion of the second radial positioning surface 74, to free a portion of the second radial positioning surface 74 between two successive cover fins 75. If more than one cover fin 75 is provided, the cover fins are spaced apart from each other around the longitudinal axis X1. Two successive cover fins 75 define between them a free portion around the longitudinal axis X1, referred to as "outer free portion 78". Preferably, the cover fins 75 are regularly distributed around the longitudinal axis X1. The present example provides four cover fins 75. However, a different number of cover fins 75 can be provided. At least, only one cover fin 75 is provided.

[0092] Preferably, each cover fin 75 is formed by two fin legs 76 spaced apart around the longitudinal axis X1. Thus, each cover fin 75 provides a free portion between the two fin legs 76, referred to as "inner free portion 77", in other words, for example, a radial notch. Thus, each cover fin 75 having two fin legs 76 constitutes a clip or a fork. In this case, each outer free portion 78 is delimited by one of the fin legs 76 of a first one of the cover fins 75 and one of the fin legs 76 of a second one of the cover fins 75, successive to the first one.

[0093] Alternatively, it can be provided that only some of the cover fins 75 form a clip, while other cover fins are formed by a single fin leg or have some other structure. Alternatively, none of the cover fins 75 forms a clip.

[0094] The cover 12 is pressed against the proximal edge 34 by the cover fins 75. To this end, as shown in Figures 1 to 4 each cover fin 75 has a second distal surface 79 extending along the assembly plane P34 and facing the distal direction X11 to press against a corresponding portion of the proximal edge 34. It is thus the second distal surface 79 that presses against the corresponding portion of the proximal edge 34 in the distal direction X11. When the cover fin 75 comprises two fin legs 76, this second distal surface 79 is distributed on each of the fin legs 76 and is interrupted at the inner free portion 77. Thus, the cover fins 75 together form an outer radial shoulder for the cover 12, ensuring the positioning of the cover 12 in the distal direction X11 relative to the base 11. Preferably, each second distal surface 79 extends the distal edge 71 of the cover 12, this distal edge of the cover extending along the same assembly plane P34. In other words, each cover fin 75 extends in the proximal direction X12 from the corresponding second distal surface 79 of this cover fin.

[0095] It can also be provided that the cover 12 is pressed against the proximal face 23 of the inner ring 20 by the cover fins 75, in particular by the second distal face 79.

[0096] As Figures 1 to 4 shown, in order to enable the spacing fins 26 and the cover fins 75 to be pressed against the proximal edge 34, the spacing fins 26 and the cover fins 75 are provided to be distributed continuously along the proximal edge 34, in other words, the spacing fins 26 and the cover fins 75 are distributed continuously around the longitudinal axis X1. In other words, each spacing fin 26 and each cover fin 75 presses on a respective portion of the proximal edge 34, which is different from the portions on which the other spacing fins 26 and the other cover fins 75 press on the proximal edge 34. In particular, the spacing fins 26 and the cover fins 75 alternate around the longitudinal axis X1. In other words, each spacing fin 26 is received in an outer free portion 78 provided between two consecutive cover fins 75.

[0097] The continuous provision of the spacing fins 26 and the cover fins 75 around the longitudinal axis X1 enables the spacing fins 26 and the cover fins 75 to be housed at the same height along the longitudinal axis X1, in other words, along the same assembly plane P34. The space required to house the spacing fins 26 and the cover fins 75 is particularly small, in particular along the longitudinal axis X1, the receptacle 10 being very compact. Furthermore, the assembly of the cover 12 on the spacer 13 is particularly easy, since by orienting the cover 12 and the spacer 13 so that the spacing fins 26 are received in the outer free portions 78 provided between the cover fins 75, it is sufficient to slide the second peripheral wall 17 into the opening provided by the first radial positioning surface 28 of the spacing fins 26.

[0098] According to the case, it can be provided that the spacer 13 is first assembled on the base 11 to form a lower assembly, then the cover 12 is added to this lower assembly to obtain the receptacle 10, or that the cover 12 is first assembled to the spacer 13 to form an upper assembly, then the base 11 is added to this upper assembly to obtain the receptacle 10.

[0099] Furthermore, it is advantageous that the cover 12 and the spacer 13 are locked, or at least positioned, in rotation relative to each other, by the anti-rotation cooperation of the spacing fins 26 with the cover fins 75. To this end, each spacing fin 26 is inserted between two consecutive cover fins 75.

[0100] Specifically, each spacer fin 26 rotates about the longitudinal axis X1 along a direct direction S29, pressing against a first cover fin in the cover fin 75, which is in contact with the outer free portion 78 receiving the spacer fin 26. The same spacer fin 26 rotates about the same cover fin 75 along an indirect direction S30, opposite to the direct direction S29, pressing against a second cover fin in the cover fin 75, which is in contact with the same outer free portion 78. These elements are anti-rotation elements about the longitudinal axis X1 because the lateral engagement of the spacer fins 26 and the cover fins 75 prevents the cover 12 from rotating relative to the spacer 13 about the longitudinal axis X1.

[0101] Specifically, each spacer fin 26 has a first lateral surface 29 and a second lateral surface 30, which define the spacer fin 26 around a longitudinal axis X1. The first lateral surface 29 forms an end of the spacer fin 26 around the longitudinal axis X1 in a direct direction S29. The second lateral surface 30 forms an end of the spacer fin 26 around the longitudinal axis X1 in an indirect direction S30. Each cover fin 75 has a third lateral surface 80, which defines the cover fin 75 along the direct direction S29, forming one end of the cover fin's ends around the longitudinal axis X1. Each cover fin 75 has a fourth lateral surface 81, which defines the cover fin 75 along the indirect direction S30, forming one end of the cover fin's ends around the longitudinal axis X1. When the cover fin 75 forms two fin legs 76, one fin leg 76 forms a third lateral surface 80, while the other fin leg forms a fourth lateral surface 81. A "lateral surface" refers to a surface oriented in an anti-rotation direction about the longitudinal axis X1, for example, along a plane including or slightly inclined relative to the longitudinal axis X1. Regardless of the orientation of the lateral surface, it has an anti-rotation orientation about the longitudinal axis X1.

[0102] like Figures 1 to 4 As shown, the second lateral surface 30 of the spacer fin 26 presses against the third lateral surface 80 of the first cover fin along the indirect direction S30, and the first lateral surface 29 presses against the fourth lateral surface 81 of the second cover fin that is continuous with the first cover fin along the direct direction S29, thereby achieving relative fixation of the cover 12 and the spacer 13 in terms of rotation.

[0103] like Figure 3Clearly visible, preferably, the second lateral surface 30 and the third lateral surface 80 are obliquely oriented and / or the first lateral surface 29 and the fourth lateral surface 81 are obliquely oriented. By "obliquely" oriented it is meant that the surfaces are oriented, for example, in a slightly helical manner (for example, by a few degrees) around the longitudinal axis XI instead of being oriented strictly along a plane parallel to the longitudinal axis XI. In particular, it can be provided that, for the same spacer fin 26, the first lateral surface 29 and the second lateral surface 30 are oblique by diverging in the distal direction XI 1, while for the same cover fin 75 the third lateral surface 80 and the fourth lateral surface 81 converge. In other words, preferably, the first lateral surface 29 and the second lateral surface 30 are slightly oriented towards the proximal direction X12, while the third lateral surface 80 and the fourth lateral surface 81 are slightly oriented towards the distal direction XI 1. Thus, by pressing the cover 12 against the spacer 13 in the distal direction XI 1, by cooperation of the first lateral surface 29 and the second lateral surface 30 with the fourth lateral surface 81 and the third lateral surface 80, respectively, a wedging of each spacer fin 26 between two cover fins 75 is obtained. More precisely, when the cover 12 is pressed against the spacer 13 in the distal direction XI 1, the third lateral surface 80 of the cover fin 75 presses against the second lateral surface 30 of the spacer fin 26 in the direct direction S29, while the fourth lateral surface 81 of the cover fin 75 presses against the first lateral surface 29 of the spacer fin 26. In fact, the force exerted on the cover 12 in the distal direction XI 1 with respect to the spacer 13 is transmitted through the angles at the oblique contact between the first lateral surface 29 and the fourth lateral surface 81 in the direct direction S29 and between the second lateral surface 30 and the third lateral surface 80 in the indirect direction S30, generating orthogonal radial force components. Thus, pressing the cover 12 against the spacer 13 in the distal direction XI 1 allows to adjust the rotational clearance between the cover 12 and the spacer 13 around the longitudinal axis XI.

[0104] Alternatively, an arrangement opposite to the one described above is provided, according to which the first lateral surface 29 and the second lateral surface 30 are converging and the third lateral surface 80 and the fourth lateral surface 81 are diverging, so that the clearance adjustment is achieved by pressing the spacer 13 against the cover 12 in the distal direction XI 1 through the first lateral surface 29, the second lateral surface 30, the third lateral surface 80 and the fourth lateral surface 81.

[0105] As Figures 1 to 4As shown, the base 11 comprises a plurality of first teeth 82 and a plurality of second teeth 87. Each first tooth 82 and each second tooth 87 protrudes from the proximal edge 34 of the base 11 in the proximal direction X12, occupying only a portion of the proximal edge 34. Each first tooth 82 and each second tooth 87 is preferably integrally formed with the first circumferential wall 16 and the proximal edge 34. More generally, each first tooth 82 and each second tooth 87 is fixed integrally with the proximal edge 34 and the first circumferential wall 16, in other words each tooth is fixed relative to the first circumferential wall 16 by attachment to this wall. If more than one tooth is provided, the teeth are spaced apart from each other around the longitudinal axis X1. Preferably, the first teeth 82 and the second teeth 87 are uniformly spaced apart around the longitudinal axis X1. The present example provides four teeth, i.e. two first teeth 82 and two second teeth 87. Preferably, the same number of teeth is provided as cover fins 75 and / or spacer fins 26. However, a different number of teeth can be provided. At least, only one tooth is provided.

[0106] Furthermore, preferably, the proximal edge 34 is entirely flat along the assembly plane P34, while each first tooth 82 and each second tooth 87 extends in the proximal direction X12 relative to the assembly plane P34. The spacer fins 26 and the cover fins 75 are received on the portion of the proximal edge 34 lacking a first tooth 82 or a second tooth 87. Thus, the spacer fins 26 and the cover fins 75, as well as the teeth, are distributed continuously around the longitudinal axis X1, or even alternately around the longitudinal axis X1. This continuous representation of the teeth, as well as the spacer fins 26 and the cover fins 75, along the same assembly plane P34, in particular along the longitudinal axis X1, saves significant space for the assembly of the receptacle 10.

[0107] Preferably, each first tooth 82 is provided as a "single tooth" formed by a single first leg 83. In the present example, two of the teeth are single teeth. Preferably, each second tooth 87 is a "double tooth" formed by two second legs 84, which are spaced apart around the longitudinal axis X1. Thus, each second tooth 87 provides a free portion between the two second legs 84. In the present example, single teeth and double teeth are provided alternately around the longitudinal axis X1. Thus, each second tooth 87 with two second legs 84 constitutes a clip or a fork. Alternatively, only single teeth or only double teeth can be provided.

[0108] The main function of the first teeth 82, i.e. of the single teeth, is to prevent the cover 12 and / or the spacer 13 from rotating relative to the base 11, each first tooth 82 being in anti-rotation support against the spacer fins 26 and the cover fins 75 around the longitudinal axis X1. For example, each first tooth 82 is in anti-rotation support either against one or more spacer fins 26, or against one or more cover fins 75, or by interposition between a spacer fin 26 and a cover fin 75.

[0109] To this end, each first tooth 82 has two fifth lateral surfaces 85, one of which faces the direct direction S29 and the other of which faces the indirect direction S30, so as to press against the complementary lateral surfaces of the spacer fin 26 and / or of the cover fin 75. The fifth lateral surfaces 85 delimit the first tooth 82 about the longitudinal axis XI.

[0110] As Figures 1 to 4 illustrated, advantageously, each first tooth 82 is rotationally pressed against the corresponding cover fin 75 about the longitudinal axis XI. To this end, although the cover fin 75 presents the form of a clip with two fin legs 76, the first tooth 82 is received in the inner free portion 77 provided between these two fin legs 76. In this case, the cover fin 75 is provided with as many fin legs as there are first teeth 82.

[0111] More precisely, advantageously, each cover fin 75 that rotationally presses against a first tooth 82 has two inner lateral surfaces 86, one of which faces the direct direction S29 and the other of which faces the indirect direction S30. Each inner lateral surface 86 is formed on one of the two fin legs 76 of the cover fin 75 so as to face the other. Thus, the inner lateral surfaces 86 delimit the inner free portion 77 of the cover fin 75 about the longitudinal axis XI between these two inner lateral surfaces 86.

[0112] By the fifth lateral surface 85 of the single tooth that faces the direct direction S29, the first tooth 82 rotationally presses against the inner lateral surface 86 of a first one of the fin legs 76 of the cover fin 75 about the longitudinal axis XI along the direct direction S29. This inner lateral surface 86 faces the indirect direction S30. By the fifth lateral surface 85 of the single tooth that faces the indirect direction S30, the first tooth 82 rotationally presses against the inner lateral surface 86 of a second one of the fin legs 76 of the cover fin 75 about the longitudinal axis XI along the indirect direction S30, this inner lateral surface 86 of the second fin leg of the cover fin facing the direct direction S29. In other words, the first tooth 82 is rotationally inserted between the two fin legs 76 of the cover fin 75 about the longitudinal axis XI. Because the rotation of the cover 12 relative to the base 11 about the longitudinal axis XI is prevented by the lateral cooperation of the spacer fin 26 with the first tooth 82, these supports are anti-rotation supports about the longitudinal axis XI.

[0113] As Figure 3Preferably, the fifth lateral surface 85 and the inner lateral surface 86 are similarly obliquely oriented with respect to the first lateral surface 29, the second lateral surface 30, the third lateral surface 80 and the fourth lateral surface 81. In particular, it can be provided that, for a same first tooth 82, the fifth lateral surface 85 is oblique while diverging in the distal direction X11, and, for a same cover fin 75, the inner lateral surface 86 is diverging. Preferably, this arrangement is provided if the third lateral surface 80 and the fourth lateral surface 81 are themselves converging in the distal direction X11. Thus, by pressing the cover 12 against the base 11 in the distal direction X11, each first tooth 82 is wedged between the fin legs 76 of a cover fin 75 by the cooperation of the fifth lateral surface 85 and the inner lateral surface 86. Specifically, when the cover 12 is pressed against the base 11 in the distal direction X11, the inner lateral surface 86 of a cover fin 75 facing the direct direction S29 presses against the corresponding fifth lateral surface 85 in the direct direction S29. Similarly, the inner lateral surface 86 facing the indirect direction S30 presses against the corresponding fifth lateral surface 85 in the indirect direction S30. In practice, the force exerted on the cover 12 with respect to the base 11 in the distal direction X11 generates, by angular transmission, an orthogonal radial force component such that the first tooth 82 is compressed between the two fin legs 76. Pressing the cover 12 against the spacer 13 in the distal direction X11 thus makes it possible to adjust the rotational clearance between the cover 12 and the base 11 around the longitudinal axis X1.

[0114] Alternatively, the oblique lateral surface of one or more cover fins can not be provided, while the oblique lateral surface of one or more spacer fins is provided to press against the fifth lateral surface 85 of a first tooth 82. Alternatively, it can be provided that, for each first tooth 82, one of the fifth lateral surfaces 85 is in contact with the oblique lateral surface of one of the spacer fins, while the other fifth lateral surface 85 is in contact with the oblique lateral surface of one of the cover fins.

[0115] More generally, the cooperation of the oblique surfaces of the spacer fins and of the cover fins and of the teeth advantageously makes it possible to clamp the cover 12, the spacer 13 and the base 11 in rotation around the longitudinal axis X1.

[0116] Optionally, the first teeth 82 can have the function of positioning the spacer 13 and / or the cover 12 with respect to the base 11, so that these elements of the receptacle 10 are coaxial with the longitudinal axis X1. To this end, for example, it can be provided that the first teeth 82 axially extend the first inner radial surface 36 of the base 11 and receive, between the single teeth, a complementary outer radial surface of the spacer 13 and / or of the cover 12.

[0117] The assembly of the cover 12 on the base 11, or of the spacer 13 on the base 11, or of the assembly made of the spacer 13 and of the cover 12 on the base 11, is particularly easy to carry out, since it is sufficient to slide the spacer fins 26 and the cover fins 75 between the first tooth 82 and the second tooth 87, which ensures the correct relative axial and rotational positioning of the cover 12, of the spacer 13 and of the base 11.

[0118] As mentioned previously, the pressing of the cover 12 against the base 11 in the distal direction X11 advantageously presses the spacer 13 against the base 11. Alternatively, the pressing of the spacer 13 against the base 11 in the distal direction X11 presses the cover against the base 11. To this end, as illustrated in Figure 5 and Figure 6 The valve system advantageously comprises a pressing ring 65 for pressing the housing 10 against the bottom wall 62 in the distal direction X11, preferably through the cover 12 or the spacer 13. This support thus makes it possible for the cover 12, the spacer 13 and the base 11 to be axially supported with respect to one another.

[0119] When the housing 10 is coupled to the cartridge seat 60, the pressing ring 65 is coaxial with the longitudinal axis X1. The pressing ring 65, for example, surrounds the cover 12 to press the housing 10 axially in the distal direction X11. Here, the pressing ring 65 presses against the cover 12, for example, by means of the outer shoulder of the second peripheral wall 17 facing in the proximal direction X12. The cover 12 is thus pressed against the spacer 13 by the inclined first lateral surface 29, the second lateral surface 30, the third lateral surface 80 and the fourth lateral surface 81 of the spacer fins 26 and of the cover fins 75, and by the distal edge 71 abutting against the proximal face 23. The cover 12 is pressed against the proximal edge 34 of the base 11 by the cover fins 75. This presses the spacer 13 against the proximal edge 34 of the base 11 by the spacer fins 26. To implement this support, the pressing ring 65 is screwed, for example, into the recess 64. To this end, the pressing ring 65 comprises, for example, a first external thread 66 which is screwed into an internal thread 67 of the recess 64 carried by the inner peripheral wall 61.

[0120] More generally, the base 11, the cover 12 and the spacer 13 are held together by the housing 10 interposed between two opposite axial forces, one of which is here exerted on the base 11 in the proximal direction X12 by the bottom wall 62 of the cartridge seat 60, and the other of which is here exerted on the cover 12 in the distal direction X11 by the pressing ring 65. Alternatively, the second force could be exerted on the spacer 13 instead of on the cover 12, by reversing the orientation of the inclined lateral surfaces on the spacer fins 26 and on the cover fins 75 appropriately.

[0121] Preferably, the device 1 includes a fastener for holding the cover 12 and the base 11 together, even when the receiving member 10 is not held together by the pressure ring 65. For this purpose, the fastener holds the base 11 relative to the cover 12 in the distal direction X11. Preferably, a portion of the fastener is formed by the cover 12 and another portion by the base 11. For example, the fastener is formed by a system that snaps the cover 12 onto the base 11 along the longitudinal axis X1, the snap-fit ​​system being tightened when the base 11 moves axially away from the cover 12, and being released when the cover 12, for example, axially abuts against the base 11 by the pressure ring 65.

[0122] In this example, a portion of the fastener is formed by two teeth in the toothed section, particularly by two second legs 84 of two second teeth 87 (i.e., double teeth), while another portion of the fastener is formed by two cover fins 75, particularly by two fin legs 76 of these two cover fins 75. The direct formation of the fastener by the cover fins 75 and the second teeth 87 particularly allows for space savings. Alternatively, it can be configured that more or fewer cover fins and associated teeth participate in forming the fastener. Alternatively, it can be configured that the fastener is formed by other elements of the cover 12 and the base 11.

[0123] For example, such as Figure 1 and Figure 4 As shown, the two second legs 84 of the second tooth 87 have snap hooks at their respective ends along the proximal direction X12, the snap hooks protruding, for example, from the sixth side of the second tooth 87 toward the surface 98. Complementarily, two corresponding fin legs 76 have snap hooks at their respective ends along the distal direction X11, the snap hooks protruding, for example, from the inside of the legs of these fin legs 76 toward the surface 70. To assemble the cover 12 with the base 11, the second legs 84 and / or fin legs 76 carrying the snap hooks can deform such that the snap hooks cross each other to engage when the cover 12 axially approaches the base 11 to reach the assembled position. Once the systems are snapped together, the cover 12 moves axially away from the base 11 in the proximal direction X12, and the snap-fit ​​system is tightened because the snap hook of the second leg 84 engages with the snap hook of the fin leg 76 in the distal direction X11 to attach the base 11 to the cover 12. However, when the cover 12 is pressed axially against the base 11 in the distal direction X11, the snap-fit ​​system is not tightened because the snap hook of the fin leg 76 is axially away from the snap hook of the second leg 84. Alternatively, it can be configured such that the snap-fit ​​system is tightened regardless of whether the cover 12 and the base 11 are axially pressed against each other.

[0124] In the example shown, when the snap system is engaged, or more generally when the cap 12 and the base 11 are attached axially by the fasteners, the spacer 13 is axially clamped between the cap 12 and the base 11, so that the housing 10 is held completely together.

[0125] In the present example, the control 3 comprises a thermostatic actuator 4 and a control member 6.

[0126] The translational position of the spool 2 is determined on the one hand by the position of the control member 6, which is actuated by the end user or by an actuator external to the device 1 once the valve system is installed, and on the other hand depends on the configuration of the thermostatic actuator 4, to thermally regulate the position of the spool 2. Alternatively, it can be provided that the control 3 does not have the thermostatic actuator 4, so that the position of the spool 2 depends entirely on the control member 6, or that the control 3 does not have the control member 6, so that the position of the spool 2 depends entirely on the thermostatic actuator 4.

[0127] Preferably, the thermostatic actuator 4 is partially housed within the proximal compartment 14 (in other words, in the cap 12) and partially housed in the distal compartment 15 (in other words, in the base 11), and passes through the inner ring 20 through the first central opening 21.

[0128] The thermostatic actuator 4 comprises a primary part 88 and a secondary part 89. Preferably, the primary part 88 forms the distal end of the thermostatic actuator 4, while the secondary part 89 forms the proximal end of the thermostatic actuator 4. Here, the thermostatic actuator 4 is coaxial with the longitudinal axis X1, so that the longitudinal axis X1 passes successively through the primary part 88 and the secondary part 89. Depending on the temperature, the thermostatic actuator 4 has a driving action that translates the secondary part 89 along the longitudinal axis X1 with respect to the primary part 88. In particular, when the temperature applied to the primary part 88 increases, the secondary part 89 translates in the proximal direction X12 with respect to the primary part 88. When this temperature decreases, the secondary part 89 translates or is made to translate in the distal direction X11 with respect to the primary part 88.

[0129] As illustrated, the thermostatic actuator 4 is for example a thermostatic element in the form of a cup. In this case, the primary part 88 forms for example a thermosensitive cup comprising a metal housing with an opening and a thermal expansion material housed within the metal housing. In this case, the secondary part 89 forms for example a rod parallel or coaxial with the longitudinal axis X1, which is partially located in the metal housing and protrudes outwardly from the metal housing, is supported by the opening and is able to slide with respect to the metal housing along the longitudinal axis X1. When its temperature increases, the thermal expansion material expands and pushes the rod in the proximal direction X12. When its temperature decreases, the thermal expansion material retracts and makes the rod able to translate in the distal direction X11.

[0130] Alternatively, it can be provided that the thermostatic actuator 4 is a shape memory alloy part in which the primary part is formed by a distal portion of the shape memory alloy part and the secondary part is formed by a proximal portion of the shape memory alloy part.

[0131] The thermostatic actuator 4 is translationally movable with respect to the housing 10, preferably by the primary part 88.

[0132] The thermostatic actuator 4 preferably passes through the inner ring 20 through the first central opening 21. Here, the proximal end of the primary part 88 is received in the first central opening 21. Advantageously, the first central opening 21 is closed by the thermostatic actuator 4, here by the primary part 88, so that the primary inflow water flow F1, the secondary inflow water flow F2 and the outflow water flow F3 circulating in the distal compartment 15 do not leak towards the proximal compartment 14. To ensure the sealing of this closure, the device 1 advantageously comprises a dynamic seal 92, such as a seal, carried by the first central opening 21.

[0133] The distal end of the primary part 88 is received in the base 11, in other words in the distal compartment 15, so as to be immersed in one of the primary inflow water flow F1, the secondary inflow water flow F2 and the outflow water flow F3 and able to react according to the temperature of this flow. Here, a majority of the primary part 88, starting from its distal end, is immersed in the outflow water flow F3. The distal end of the primary part 88 is preferably received in the mixing chamber 33. The relative position of the primary part 88 and the secondary part 89 thus depends on the temperature of the outflow water flow F3. Preferably, the primary part 88 passes through and is surrounded by the distal seat 38 and the proximal seat 39.

[0134] In the present example, the spool 2 and the primary part 88 are fixed with respect to each other, at least in terms of translation along the longitudinal axis X1. In the present example, the spool 2 is fixed to the primary part 88 by screwing to the primary part. As illustrated, the primary part 88 passes through a second central opening 91 of the spool 2, for example, which is centred on the longitudinal axis X1 and through which the spool 2 is fixed to the primary part 88. The position of the spool 2 with respect to the housing 10 thus corresponds to the position of the primary part 88.

[0135] Preferably, the control piece 3 comprises a return spring 90 which exerts an elastic force on the main piece 88 in the proximal direction X12 relative to the housing 10. For example, the return spring 90 is a compression spring which is axially inserted between the main piece 88 (for example via a shoulder carried by the main piece 88) and the bottom 18 of the base 11. As will be described below, the return spring 90 has the function of returning the main piece 88 and the secondary piece 89 towards each other along the longitudinal axis X1 when the temperature of the outflowing water flow F3 drops by pressing the thermostatic actuator 4 against the rest of the control piece 3 in the proximal direction X12.

[0136] The proximal end of the secondary piece 89 extends into the cover 12, in other words into the distal compartment 15.

[0137] Preferably, the control member 6 passes through the control opening 19 so that the distal end of the control member 6 is housed within the proximal compartment 14, in other words within the cover 12, while the proximal end of the control member 6 projects from the housing to be actuated by the end user or mechanically connected to an external actuator.

[0138] Alternatively, the control member 6 is completely housed within the proximal compartment 14, accessible from the outside of the housing 10 through the control opening 19.

[0139] Here, the control member 6 can pivot about the longitudinal axis X1 relative to the housing 10. For example, the control opening 19 supports such rotation. Thus, the control member 6 constitutes a control button. Conversely, the control member forms a lever or any other control handle.

[0140] If necessary, the control member 6 actuates the secondary piece 89 translationally through the mechanical transmission 7 and the overtravel compensation system 5 belonging to the control piece 3.

[0141] If necessary, the mechanical transmission 7 has the function of converting the movement of the control member 6 into a translation of the main piece 88. The mechanical transmission 7 is completely housed in the cover 12.

[0142] Here, since the control member 6 is pivotable with respect to the housing 10 about the longitudinal axis XI, the mechanical transmission 7 is for example in the form of a screw connection. To this end, the mechanical transmission 7 comprises for example a slider 94, a second external thread 93 formed directly at the distal end of the control member 6, and an anti-rotation guide 99 formed directly by the inner radial surface of the second circumferential wall 17 of the cover 12. The slider 94 has the form of a ring-shaped part centered on the longitudinal axis XI, which can be moved translationally with respect to the housing 10 along the longitudinal axis XI, while being prevented from rotating with respect to the housing about the longitudinal axis XI, by cooperating with the anti-rotation guide 99. To this end, the slider 94 has for example an outer radial groove parallel to the longitudinal axis XI, which mechanically cooperates with the anti-rotation guide 99, which forms an inner radial groove parallel to the longitudinal axis XI. The slider 94 also has an inner thread, which cooperates in a screw connection with the second external thread 93 of the control member 6. Rotation of the control member 6 with respect to the housing 10 about the longitudinal axis XI then causes a translational movement of the slider 94 with respect to the housing 10 along the longitudinal axis XI. The second external thread 93 is advantageously configured such that the connection is irreversible, so that a translational actuation of the slider 94 does not cause a rotation of the control member 6.

[0143] When the thermostatic actuator 4 is set, the control 3 advantageously comprises the above-mentioned overtravel compensation system 5. It is thus advantageous that the slider 94 actuates the slide valve 2 both through the overtravel compensation system 5 and the thermostatic actuator 4. Preferably, this overtravel compensation system 5 is entirely received in the proximal compartment 14, in other words in the cover 12.

[0144] In order to protect the integrity of the device 1, for example in the event of a sudden and / or significant increase in the temperature of the outflow water flow F3, the overtravel compensation system 5 is arranged for the case where the thermostatic actuator 4 enters an overtravel situation. In the overtravel situation, the main part 88 of the thermostatic actuator 4 is pressed against the housing 10 in the distal direction XI 1 by pressing the slide valve 2 against the distal seat 38, while the thermostatic actuator generates a force that continues to displace the secondary part 89 with respect to the main part 88 in the proximal direction X12.

[0145] The thermostatic actuator 4 is held against the overtravel compensation system 5 in proximal direction X12 by a return spring 90. To this end, the secondary part 89 is pressed against the overtravel compensation system 5 in proximal direction X12. The overtravel compensation system 5 is held against the slide 94 in proximal direction X12 by the thermostatic actuator 4 by a return spring 90. In the present example, the overtravel compensation system 5 comprises a proximal plunger 96 by which the overtravel compensation system 5 is held against the slide 94, a distal plunger 97 by which the thermostatic actuator 4 is held against the overtravel compensation system 5, and an overtravel spring 95 which exerts an axial elastic force on the proximal plunger 96 relative to the distal plunger 97. The distal plunger 97 is movable in translation relative to the proximal plunger 96 along the longitudinal axis X1. The elastic force exerted by the overtravel spring 95 is opposite to the displacement of the distal plunger 97 relative to the proximal plunger 96 in proximal direction X12, thereby exerting a force in distal direction X11.

[0146] In the present example, the proximal plunger 96 has the form of a sleeve centered on the longitudinal axis X1 which entirely accommodates the overtravel spring 95 for reasons of compactness. The proximal plunger 96 comprises an outer radial shoulder formed at the distal end of the sleeve by which the proximal plunger 96 is axially held against the slide 94. The overtravel spring 95 is a compression spring held in proximal direction X12 against an inner radial shoulder of the proximal plunger 96 formed at the proximal end of the sleeve. The distal plunger 97 slides inside the sleeve. The distal end of the overtravel spring 95 is pressed against the distal plunger 97 in distal direction X11, while the secondary part 89 is pressed against the distal plunger 97 in proximal direction X12.

[0147] In the basic configuration of the overtravel compensation system 5 obtained when the thermostatic actuator 4 is not in an overtravel situation, the distal plunger 97 is held in a distal position relative to the proximal plunger 96 under the action of the overtravel spring 95, for example against the inner radial shoulder of the proximal plunger 96 formed at the distal end of the sleeve. Then, like the secondary part 89 held directly against the slide 94 in proximal direction X12, the overtravel compensation system 5 rigidly transmits the axial position of the slide 94 to the secondary part 89 of the thermostatic actuator 4. To this end, the return spring 90 and the overtravel spring 95 are configured so that the elastic force exerted by the overtravel spring 95 is greater than the elastic force exerted by the return spring 90, to prevent the return spring 90 from being able to overcome the force of the overtravel spring 95 and displace the distal plunger 97 in proximal direction X12 relative to the slide 94 when the thermostatic actuator 4 is not in an overtravel situation.

[0148] In the overtravel configuration of the overtravel compensation system 5 obtained when the thermostatic actuator 4 is in an overtravel situation, by making the spool 2 enter into a distal position against the distal seat 38, the distal plunger 97 moves translationally in the proximal direction X12 with respect to the distal position of the distal plunger 97 against the overtravel spring 95 under the action of the force directed in the proximal direction X12 generated by the thermostatic actuator 4 and transmitted by the secondary part 89 to the distal plunger 97, while the thermostatic actuator 4 is pressed against the containment 10 in the distal direction X11.

[0149] Alternatively, if the overtravel compensation system 5 is not provided, it can be provided that the slider 94 is directly integral with the secondary part 89 of the thermostatic actuator 4 for axial translation to actuate the spool 2 by the thermostatic actuator 4. If the thermostatic actuator is not provided, it can be provided that the slider 94 is directly integral with the spool 2 for axial translation.

[0150] In operation, the spool 2 can be displaced by acting on the control member 6 to adjust the proportion of the mixture of the primary water inflow F1 and the secondary water inflow F2 forming the outflow water flow F3. The translation position of the spool 2 depends on the position of the control member 6, which is transmitted to the spool 2 by the mechanical transmission 7, the overtravel compensation system 5 and the thermostatic actuator 4.

[0151] According to the temperature of the outflow water flow F3, the thermostatic actuator 4 implements a correction of the position of the spool 2, since, according to the temperature of the outflow water flow F3, the primary part 88 and the secondary part 89 move one with respect to the other along the longitudinal axis X1 and, therefore, the primary part 88 translationally moves with respect to the slider 94, displacing the spool 2 accordingly.

[0152] Figure 7 and Figure 8 The embodiment shown relates to the same device as that of Figures 1 to 6 , with the difference that:

[0153] For this embodiment in Figure 7 and Figure 8 , the base 11 comprises only the first teeth 82 (i.e. single teeth), in other words the first teeth have a single first leg 83, the number of teeth being for example two. The base 11 comprises only two cover fins 75, each cover fin 75 receiving one of the two first teeth 82 in the inner free portion 77 of the cover fin. The cover fins 75 and the first teeth 82 do not have any snap means, therefore do not form an axial attachment to axially retain the cover 12 with respect to the base 11.

[0154] For this embodiment in Figure 7 and Figure 8 , the fastener is still formed by the base 11 and the cover 12. The fastener forms a snap system comprising the lugs 101 and the snap stops 102.

[0155] Lug 101 is formed by the cover body 12, and the lug is integrally formed with the rest of the cover body 12. The number of lugs 101 is, for example, two, and the lugs are evenly distributed around a longitudinal axis X1. The lugs 101 are attached, for example, near the distal edge 71, to a second circumferential wall 17. The distal end of each lug 101 extends along the distal direction X11 of a first circumferential wall 16 of the base to cover a corresponding radially outer portion 104 of the first circumferential wall 16. Each radially outer portion 104 is radially recessed to at least partially accommodate the lug 101. Each snap-on stop 102 is formed on the surface of the first circumferential wall 16 within one of the radially outer portions 104 covered by the corresponding lug 101. Preferably, each snap-on stop 102 is received in a corresponding snap-on opening 103 in the corresponding lug 101. The cover 12 is held relative to the base 11 in the proximal direction X12 by the engagement of the snap stop 102 and the snap opening 103.

[0156] for Figure 7 and Figure 8 In this embodiment, device 1 includes a fastener formed by a base 11 and a spacer 13, by which the spacer 13 is attached to the base 11 such that the base 11 is held relative to the spacer 13 in a distal direction X11. This has the advantage that the spacer 13 and the base 11 remain together even before the cover 12 is assembled, which is particularly convenient during the manufacturing process of device 1. Advantageously, this fastener is provided when it is planned to first assemble the base 11 with the spacer 13 and then assemble the cover 12.

[0157] Preferably, the fastener constitutes a hooking system. The fastener comprises, for example, hooks 111 formed by the base 11 and complementary notches 112 formed by the spacer 13. For example, four hooks 111 and four corresponding notches 112 are provided. The hooks 111 can be hooked to the notches 112 to attach the base 11 to the spacer 13. As illustrated, the hooks 111 are advantageously provided to protrude from the proximal edge 34, while the notches 112 are formed by the spacer fin 26, in particular at the second lateral surface 30 of the spacer fin 26. Preferably, the hooks 111 and the notches 112 have opposite orthogonal radial orientations, since the hooks 111 are, for example, open in the indirect direction S30, and the notches 112 are, for example, open in the direct direction S29. Thus, to hook the base 11 to the spacer 13, the inner ring 20 of the spacer 13 is first axially inserted into the proximal opening 35 of the base 11. During this insertion, it is ensured that the spacer 13 is in an assembly orientation relative to the base 11 about the longitudinal axis X1. In this assembly orientation, the spacer 13 is offset relative to its final position about the longitudinal axis X1 in the direct direction S29. Then, the spacer 13 is rotated relative to the base 11 in the indirect direction S30 to move the spacer from the assembly orientation to the final orientation and thus to orthogonally radially engage the hooks 111 and the notches 112 with each other. The spacer 13 is then attached to the base 11 by the cooperation of the hooks 111 and the notches 112.

[0158] Alternatively, it can be provided that the attachment of the base 11 to the spacer 13 comprises a snap lug instead of the aforementioned hooking system.

[0159] Figure 9 and Figure 10 The illustrated embodiment relates to the same device as the device of Figures 1 to 6 with the following differences.

[0160] For the embodiment in Figure 9 and Figure 10 The device 1 comprises a fastener formed by the spacer 13 and the cover 12, by which the spacer 13 is attached to the cover 12 so that the spacer 13 is held relative to the cover 12 in the distal direction X11. This has the advantage that the spacer 13 and the cover 12 are held together even if the base 11 has not yet been assembled, which is particularly convenient during the manufacturing process of the device 1. Advantageously, the fastener is provided when it is planned to first assemble the cover 12 with the spacer 13 and then to assemble the base 11.

[0161] Preferably, the fastener constitutes a snap system. For example, the fastener comprises snap hooks 121 formed by the spacer 13 and snap notches 122 formed by the cover 12.

[0162] Here, the number of snap hook portions 121 is two and the snap hook portions are evenly distributed around the longitudinal axis X1, but a different number of snap hook portions 121 can be provided. Each snap hook portion 121 projects from the proximal face 23 in the proximal direction X12 and opens radially outward, for example.

[0163] Each snap recess 122 is formed in the second circumferential wall 17, for example, the recess opens radially inward to receive one of the snap hook portions 121. Here, each snap recess 122 even extends radially through the second circumferential wall 17. Each snap recess 122 opens radially outward, for example, at the base of one of the cover fins 75.

[0164] Thus, assembling the spacer 13 to the cover 12 involves snapping the snap hook portions 121 into the snap recesses 122. More precisely, when the spacer 13 is assembled into the cover 12 in the proximal direction X12, the snap hook portions 121 are deformed radially inward until the hook portions reach the snap recesses 122 at which the snap hook portions 121 resume the original radially outer shape of the hook portions, thereby hooking into the snap recesses 122 and retaining the spacer 13 relative to the cover 12 in the distal direction X11.

[0165] Alternatively, it can be provided that the cover 12 comprises the hook portions and the spacer 13 has the recesses, to provide a fastener with similar operation.

[0166] Any feature described above in relation to one embodiment or variant can be implemented in relation to other described embodiments and variants, where technically possible.
