Description

Title of the invention: MODULAR MULTI-WAY VALVE Technical field of the invention

[0001] The present invention relates to a multi-way valve configured to allow the circulation of a fluid through several fluid passages. Technical background

[0002] Multi-way valves are commonly used to allow a fluid to be directed through different fluid passages depending on the desired use.

[0003] Typically, multi-port valves consist of a plug mounted for rotation within a main valve body. The main valve body then comprises at least two openings configured to be fluidly connected to each other by a channel formed in the plug.

[0004] Thus, the rotation of the plug within the main body contributes to the formation of the fluid passage of the valve and thus allows the fluid to be directed from one of the openings of the main body to the other opening.

[0005] The bushing then carries fluidic sealing elements so as to seal the fluidic passageway formed between the openings of the main body and its channel.

[0006] However, the positioning of the fluidic sealing elements on the plug presents disadvantages, particularly with regard to the correct positioning of the latter and also with regard to the solidity of this positioning over time.

[0007] Moreover, current multi-way valves do not allow adaptation to different usage needs and thus lack modularity in the configuration of fluid passage paths.

[0008] Thus, there is currently a need for improved sealing and modularity of multi-way valves.

[0009] In fact, the aim of the invention is to provide a multi-way valve whose sealing performance is improved while offering increased modularity in the configuration of the fluid passageways. Summary of the invention

[0010] The invention proposes a multi-way valve comprising at least a main body and a plug, the main body delimiting an internal volume configured to receive the plug,

[0011] the main body forming at least two tubes extending along two distinct axes, each tube comprising an inlet at its axial end external and an outlet at its internal axial end opening into the internal volume of the main body,

[0012] the main body comprising at least two annular ribs extending outside the internal volume, each annular rib extending around at least one of the inlet openings of one of the tubes,

[0013] the valve comprising at least two inserts,

[0014] each insert comprising at least one internal tip configured to fit into one of the tubes,

[0015] each insert comprising an annular structure which includes at least one radial extension configured to be in contact with the annular rib when the inner tip is inserted into the tubing,

[0016] each insert comprising a fluidic sealing element fitted onto the inner tip and configured to be in contact with the plug when the inner tip is inserted into the tubing.

[0017] According to other features of the invention: - the main body comprises at least two annular portions which each extend coaxially around one of the tubing, the first two annular ribs each extending axially in projection from an external crown of one of the annular portions; - the inner tip of each of the inserts includes an end forming a neck, the fluidic sealing element having an annular shape delimited by a peripheral wall and at the end of which extends a sealing lip configured to cover at least part of the neck of the inner tip and so as to be in contact with the plug when the inner tip is lodged in the tubing; - the neck of the internal tip has a concave shape, the sealing lip of the sealing element has a concave shape complementary to the neck; - the inner tip includes peripheral guide ribs and the peripheral wall of the fluidic sealing element includes internal grooves configured to cooperate with the guide ribs, so as to define the angular position of the sealing element on the inner tip; - an angular error-proofing means is formed on an inner lateral surface of each of the annular portions and at least one of the inserts includes a complementary error-proofing element capable of cooperating with the angular error-proofing means so as to define an angular position of the insert relative to the tubing; - each of the inserts delimits a fluid passage channel allowing the passage of a fluid through the tubing when the insert is mounted in the tubing or forms a plug blocking the passage of a fluid through the tubing; - the main body comprises at least two second annular ribs which each extend circularly and coaxially around one of the inlet mouths of one of the tubes and in such a way that each extends into a volume delimited by one of the annular portions; - the second annular ribs are axially offset relative to the first annular ribs, considering the axis of their respective tubing; - the valve includes at least one insert whose radial extension is configured to be in contact with one of the second annular ribs when its internal tip fits into the tubing; - at least the two pipes include their inlet openings which extend in a common plane; - the main body includes a third rib which extends around the periphery of the first annular ribs associated with at least two tubes whose inlet openings extend in a common plane; - the valve includes a fluidic connection piece configured to cover at least the two inlet ports which extend in a common plane, of at least two pipes, the fluidic connection piece including at least one connecting wall which extends in overlap of the third rib.

Detailed description of the invention

[0030] In the description that follows, identical, similar or analogous elements will be designated by the same reference numerals.

[0031] Fig. 1 illustrates a so-called multi-way valve 10 according to a first example.

[0032] The valve 10 includes a main body 12, particularly visible in [Fig.2], delimiting an internal volume 14 configured to receive a plug 16 of the valve 10, visible in [Fig.3].

[0033] More precisely, the main body 12 comprises a main wall 18 whose internal surface delimits the internal volume 14 of the main body 12.

[0034] In relation to [Fig.2], the main wall 18 extends around a first axis RI here of revolution, so as to present a general cylindrical shape.

[0035] Thus, considering [Fig.3], the bushing 16 housed in the internal volume 14 has a peripheral shape complementary to the shape of the main wall 18, that is to say a cylindrical peripheral shape, coaxial with the first axis RI of revolution.

[0036] Furthermore, the bushing 16 has a diameter strictly smaller than an internal diameter of the main wall 18 of the main body 12, such that a non-zero radial distance persists between an external periphery of the bushing 16 and a surface internal of the main wall 18 of the main body 12, thus allowing the rotation of the plug 16 in the internal volume 14 without friction.

[0037] As can be seen in the example of figures 3 and 4, the bushing 16 comprises two internal channels 20 each opening onto two peripheral orifices 22.

[0038] In particular, each of the internal channels 20 allows a fluid to be guided from one of its peripheral orifices 22 to its other peripheral orifice 22.

[0039] The bushing 16, according to the illustrated example, is mounted on a drive shaft 24 configured to rotate said bushing 16 via a drive unit 26, visible in [Fig.1].

[0040] More particularly, the drive unit 26 includes at least one drive motor, not visible, capable of rotating the drive shaft which itself drives the slide 16 to which it is linked in rotation, around the first axis of rotation RI so as to modify the angular position of the slide 16 within the internal volume 14.

[0041] As seen in [Fig.3], the main body 12 of the valve 10 includes a lower axial opening 28, opening into the internal volume 14, and through which the plug 16 is mounted in the internal volume 14 of the main body 12.

[0042] Thus, when the bushing 16 is mounted in the internal volume 14 of the main body 12, the drive shaft 24 extends at least in part through the lower axial opening 28 so as to be linked to the drive unit described above.

[0043] The functionality of the plug 16 within the multi-way valve 10 will be detailed later in the rest of the description.

[0044] In relation to the example of [Fig.2], the main body 12 of the valve 10 comprises four tubes 30, each participating in forming one of the fluid passageways of the valve 10.

[0045] Each of the tubing 30 of the main body 12 opens into the internal volume 14 of the main body 12 of the valve 10.

[0046] More particularly, the four tubes 30 extend circularly around the first axis RI, here of revolution, and are angularly spaced from each other by an angle of equal degree.

[0047] According to the illustrated example, each of the tubes 30 extends around a second axis R2, here of revolution, distinct.

[0048] According to the illustrated example, each of the second axes R2 of revolution is perpendicular to the first axis RI of revolution.

[0049] Considering their respective second axis of revolution R2, each of the tubes 30 extends axially between an inlet 32 ​​and an outlet 34, the outlet 34 being the outlet opening into the internal volume 14 of the main body 12.

[0050] In other words, the inlet mouth 32 of each tube 30 is positioned at an external axial end of its tube 30 and the outlet mouth 34 of each tube 30 is positioned at an internal axial end of its tube 30, considering the respective second axis R2 of revolution of each tube 30.

[0051] As seen in [Fig.2], a first annular rib 36 extends circularly around the periphery of each of the tubing 30.

[0052] It should be considered that, in the following description, the structural environment associated with a single tube 30, such as the first annular rib 36, will be detailed, but that these structural characteristics apply mutatis mutandis to all the tubes of the valve 10.

[0053] Particularly visible in [Fig.2], an annular portion 38 extends coaxially around the inlet mouth 32 of the tubing 30 and outside the internal volume 14 of the main body 12.

[0054] An internal ring 40 of the annular portion 38 is then defined, turned towards the main wall 18 of the main body, and an external ring 42 of the annular portion 38 turned away from the main wall 18, considering the second axis R2 of revolution associated.

[0055] In relation to [Fig.3] and considering the second axis R2 of revolution, we define a first diameter DI of the inlet mouth 32 and a second internal diameter D2 of the annular portion 38, the second diameter D2 being here strictly greater than the first diameter Dl.

[0056] In other words, the annular portion 38 extends at a non-zero radial distance from the circumference of the inlet mouth 32 of the tubing 30.

[0057] Thus and according to the illustrated example of [Fig.2], which is not limiting, a connecting surface 44 extends radially from the circumference of the inlet mouth 32 of the tubing 30 to an inner lateral surface 48 of the annular portion 38 and in such a way that it connects them.

[0058] As can be seen in figures 2 and 6, the first annular rib 36 extends axially in projection from the outer ring 42 of the annular portion 38, considering the second axis R2 of revolution of the associated tubing 30.

[0059] More precisely, the first annular rib 36 extends circularly and coaxially, considering the second axis R2 of revolution, around its tube 30.

[0060] It is then understood that the first annular rib 36 is offset from the inlet mouth 32 of the associated tubing 30, along axial and radial directions considering the second axis R2 of revolution.

[0061] As particularly visible in [Fig.3], an angular error-proofing means 46 projects outward from the inner lateral surface 48 of the annular portion 38.

[0062] According to the illustrated example, the angular error-proofing means 46 comprises two lugs 46a which project outwards from the inner lateral surface 48 of the annular portion and which angularly delimit a receiving space 46b for a complementary error-proofing member 66, visible in [Fig.5].

[0063] The cooperation between the angular error-proofing means 46 and the complementary error-proofing member 66 will be detailed further in the continuation of the detailed description.

[0064] As can be seen in the example embodiment of [Fig.1], the multi-way valve 10 comprises four inserts 50, each configured to fit at least partially into one of the tubing 30 described previously.

[0065] It should be considered that, in the following description, only one of the inserts 50 associated with one of the tubes 30 will be described, but that the structural and functional characteristics of the described insert 50 apply mutatis mutandis to all the inserts of the valve 10.

[0066] The insert 50, 50a here takes the form of a tube which extends coaxially to the second axis R2 of revolution of its associated tubing 30, when it is mounted in the latter.

[0067] In relation to figures 5 and 6, an inner lateral face of the insert 50, 50a delimits a fluid passage channel 52 of the insert 50, 50a.

[0068] The insert 50, 50a according to this example is axially delimited by an internal tip 54 and an external tip 56, the internal tip 54 being configured to fit into the associated tubing 30 and the external tip 56 being configured to extend out of the associated tubing 30 when the insert 50 is mounted in the tubing 30 as seen in [Fig.6].

[0069] It is then understood that the external tip 56 is configured to be fluidically coupled to an auxiliary fluidic connection, not visible here.

[0070] Furthermore, the insert 50, 50a includes an annular structure 58 which extends radially from an external lateral face 60 of the external tip 56 of the insert 50, 50a.

[0071] More particularly, the annular structure 58 is formed at least by a radial extension 62 configured to be axially in contact with the first annular rib 36 described previously, when the insert 50, 50a is mounted in its tubing 30, as seen in [Fig.6].

[0072] In other words, the radial extension 62 is configured to extend radially until it covers the first annular rib 36.

[0073] Thus, it is understood that the contact of the radial extension 62 with the first annular rib 36 forms an axial stop of the insert 50, 50a with respect to the tube 30.

[0074] Furthermore, the contact between the radial extension 62 and the first annular rib 36 creates a welding zone where these two elements can be welded together. Such a welding operation allows, in particular, the insert 50, 50a to be joined to the main body 12, and specifically within its tube 30.

[0075] According to a non-limiting example, the welding between the radial extension 62 and the first annular rib 36 is implemented by laser welding.

[0076] It is understood, moreover, that at least the tubes and inserts are made of a material compatible with a welding operation, for example laser welding.

[0077] Furthermore, according to the example of the insert 50, 50a visible in [Fig.5], the annular structure 58 comprises a set of overthicknesses 64 which extend axially from the radial extension 62 and in such a way that they are positioned axially between the radial extension 62 and the bonding surface 44 described previously, when the insert 50 is mounted on its tube 30, as seen in [Fig.6].

[0078] The set of overthicknesses 64 thus forms a structural reinforcement of the radial extension 62 allowing to limit the risks of deformation when a force is applied to the insert 50, 50a for its introduction into the tube 30, as described previously.

[0079] Moreover, and as can be seen in [Fig.5], the set of overthicknesses 64 forms the complementary error-proofing element 66, configured to cooperate with the angular error-proofing means 46 described previously.

[0080] More particularly, the complementary error-proofing element 66 has a complementary shape with the angular error-proofing means 46.

[0081] More precisely, the additional error-proofing element 66 is here formed by radial clearance zones configured to receive the lugs of the angular error-proofing means and between which extends a radial portion intended to fit in the angular space of the angular error-proofing means.

[0082] Such cooperation between the angular misalignment means 46 and the complementary misalignment member 66 makes it possible on the one hand to define an angular position of the insert 50, 50a relative to the tube 30 and on the other hand to lock said angular position defined before welding of the insert 50, 50a on the first annular rib 36 as described previously.

[0083] Still visible in [Fig. 5], the inner tip 54 of the insert 50, 50a includes a end forming a collar 68, which has a curved shape.

[0084] More precisely, the neck 68 of the internal tip 54 has a shape concave.

[0085] As seen in [Fig.6], the neck 68 of the internal tip 54 is directed towards the bushing 16 housed in the internal volume 14 of the main body 12.

[0086] Thus, it is understood that the neck 68 of the internal end 54 has a complementary shape with the cylindrical-shaped bushing 16 described previously.

[0087] As seen in figures 5 and 6, the insert 50, 50a includes a fluidic sealing element 70.

[0088] According to the illustrated example in figures 5 and 6, the fluidic sealing element 70 is fitted onto the internal end 54 of the insert 50, 50a.

[0089] More precisely, the fluidic sealing element 70 comprises a peripheral wall 72 arranged to cover an outer shell 61 of the inner tip 54, and comprises a sealing lip 74 which extends to the end of the peripheral wall 72 and such that it covers the neck 68 of the inner tip 54.

[0090] Thus, it is understood that when the insert 50, 50a is mounted in its tubing 30, the sealing lip 74 is arranged axially between the neck 68 of the internal end 54 and the plug 16, as seen in [Fig.6].

[0091] Furthermore, the sealing lip 74 is configured to be in contact with the plug 16 in such a way that it ensures fluidic sealing between the fluid passage channel 52 of the insert 50 and the plug 16, once the welding operation of the insert 50 has been carried out.

[0092] It is further understood that the fluidic sealing lip 74 ensures fluidic sealing between the fluidic passage channel 52 of the insert 50 and the internal channel 20 of the plug 16 when one of the peripheral orifices 22 of the plug 16 is positioned opposite the neck 68 of the internal end 54.

[0093] According to a non-limiting example of the invention, at least the sealing lip 74 is made of a flexible material such that it resists compressive forces against the plug 16, defined by the welding operation, while not hindering the rotation of the latter in the internal volume 14, as described above.

[0094] For example, the fluidic sealing element 70 is made of EPDM and PTFE. The advantage of the PTFE material is that it limits the friction of the sealing element against the plug during the operation of the valve 10.

[0095] Furthermore, the fluidic sealing element 70 has a complementary shape with the neck 68 of the internal nozzle 54.

[0096] In other words, it is understood that the fluidic sealing element 70 is configured in such a way that its sealing lip 74 has a concave profile complementary to the cylindrical shape of the plug 16.

[0097] As seen in [Fig. 5], the inner tip 54 includes peripheral guide ribs 76 that project outwards from its outer casing 61, and according to an axial direction considering the second axis R2 of revolution of the associated tubing.

[0098] In addition, the peripheral wall 72 of the fluidic sealing element 70 includes internal grooves 78 configured to cooperate with the peripheral guide ribs 76 formed on the internal end 54.

[0099] It is then understood that the cooperation between the guide ribs 76 and the internal grooves 78 forms a means of error correction ensuring proper angular positioning of the fluidic sealing element 70 on the internal end 54.

[0100] Thus, the cooperation between the guide ribs 76 and the internal grooves 78 allows the angular positioning of the fluidic sealing element 70 on the internal end 54 to be guided and to ensure its correct position.

[0101] Moreover, the cooperation between the guide ribs 76 and the internal grooves 78 ensures that the complementary shapes of the sealing lip 74 and the neck 68 couple adequately, as described previously.

[0102] As seen in [Fig.2], the main body 12 includes a top axial opening 80, axially opposed to the bottom axial opening 28, considering the first axis RI of revolution.

[0103] The upper axial opening 80 is delimited by a peripheral rib 82 extending axially in projection.

[0104] According to the example in [Fig.1], a cap 84 is configured to close the upper axial opening 80.

[0105] More precisely, the cap 84 is configured to rest on the peripheral rib 82.

[0106] Thus, welding the cap 84 over the upper axial opening 80, via the peripheral rib 82, makes it possible to close the upper axial opening 80 in a watertight manner.

[0107] It should also be considered that, in a non-limiting manner, a fifth insert as described above could be inserted into the upper axial opening, the valve plug then having a structure adapted to this fifth insert so as to form another fluid passage between this fifth insert and the other inserts already described.

[0108] The operation of the bushing 16 according to the example of [Fig.1] will now be described in detail by means of [Fig.4].

[0109] As seen in [Fig.4], the bushing 16 has its four peripheral orifices 22 which are distributed in such a way that each one is spaced at an angle of 90° from a circularly adjacent peripheral orifice.

[0110] It is then understood that such an arrangement of the peripheral orifices 22 of the plug 16 allows each of them to cooperate with one of the fluid passage channels 52 of one of the inserts 50, 50a when these are inserted into their tubing 30.

[0111] Thus and according to the non-limiting example illustrated in [Fig.4], the cooperation between the inserts 50 and the plug 16 makes it possible to form two fluidic paths VI, V2 in the multi-way valve 10.

[0112] In particular, each of the VI, V2 channels allows fluidic circulation from one of the fluidic passage channels 52 of one of the inserts 50 to one of the internal channels 20 of the plug and then to the fluidic passage channel 52 of one of the inserts 50 angularly adjacent to the other insert 50.

[0113] It is also understood that the rotation of the plug 16 as described above makes it possible to modify the trajectories of the two fluidic paths VI, V2 of the valve 10 by connecting fluidic passage channels 52 of different adjacent inserts 50.

[0114] According to an example in [Fig.7], the multi-way valve 10 may include a check valve 85 housed in at least one of its inserts 50.

[0115] The non-return valve 85 allows, among other things, the passage of a fluid in only one direction of circulation without risk of return of the fluid in the opposite direction.

[0116] For example, the check valve 85 can be configured to allow the circulation of a fluid in an inward direction, i.e. towards the internal volume of the main body 12 of the valve 10, or in an outward direction, i.e. towards a volume outside the valve 10.

[0117] The non-return valve 85 is here disposed in the fluid passage channel 52 of one of the inserts 50, at least at the level of the external tip 56 of said insert 50.

[0118] According to other examples not illustrated, it can be foreseen that the valve integrates a pressure and / or temperature sensor in one of the fluid passage channels of one of the inserts.

[0119] A second embodiment of valve 10 will now be described by means of figures 8 to 11.

[0120] It should therefore be considered that only the distinct structural and functional characteristics of the first example described in Figures 1 to 7 will be detailed here. For the common characteristics, reference should be made to the first example of the invention in Figures 1 to 7.

[0121] Furthermore, in this second embodiment of the valve 10, several examples of inserts 50 will be described. The insert 50, 50a described in Figures 1 to 7 will be designated as the first example of an insert 50a.

[0122] As can be seen in figures 8 and 9, the main body 12 of the multi-way valve 10 comprises at least two pipes 30 of which at least the inlet ports 32 extend in a common plane.

[0123] For example and without limitation, the common plane of the inlet mouths 32 of the at least two pipes 30 is a radial plane considering the axes R2 of revolution of said at least two pipes 30.

[0124] Thus, the valve 10 of the example illustrated in Figures 8 to 11 is a valve 10 commonly referred to as a "two-stage valve".

[0125] In the illustrated example, the valve 10 comprises, but is not limited to, four pairs 86 of tubing 30, each pair 86 of tubing 30 comprising its inlet ports 32 which extend in a common plane.

[0126] Thus, by pair 86 of tubing 30, we mean two tubing 30s of which at least the inlet mouths 32 extend in a common plane, here a radial plane considering the axes R2 of revolution of the tubing 30 of the pair 86 of tubing 30.

[0127] The pairs 86 of tubing 30 are here and in a non-limiting manner, angularly spaced from each other by an angle of equal degrees.

[0128] According to the illustrated example, the pairs 86 of tubing 30 are spaced from each other at an angle equal to 90°.

[0129] According to another example not shown, the valve may comprise three pairs of tubing, spaced apart from each other at an angle equal to 120°.

[0130] It should also be considered that the valve may comprise more than two pipes whose inlet mouths extend in the same common plane so as to form a three-stage, four-stage or more valve.

[0131] In the illustrated example, the outlet mouths 34 of the pipes 30 of each pair 86 of pipes 30 also extend in a common plane.

[0132] In the following description, only one pair 86 of tubing 30 will be detailed, but it should be considered that the functional and structural characteristics described in relation to the pair 86 of tubing 30 apply mutatis mutandis to all pairs 86 of tubing 30 of the multi-way valve 10.

[0133] As seen in [Fig. 10], an insert 50, 50a according to the first example is mounted in one of the tubes 30 of the pair 86, while an insert 50b according to a second example is mounted in the other tube 30 of the pair 86 of tubes 30.

[0134] The insert 50b according to the second example includes the internal tip 54 which delimits a part of the fluid passage channel 52 and the annular structure 58 having here the form of a solid structure so as to close one end of the internal tip 54.

[0135] It is therefore understood that the annular structure 58 of the insert 50b according to the second example, closes one end of the fluid passage channel 52.

[0136] In other words, the insert 50b according to the second example forms a plug.

[0137] As with the first example of insert 50a, the annular structure 58 of insert 50b according to the second example includes the radial extension 62 which extends radially so that it rests on the first annular rib 36 associated with the tubing 30.

[0138] It is then understood that the insert 50b according to the second example allows the fluid passage channel 52 to be fluidically closed at one end of the internal tip 54 and thus allows the circulation of a fluid to be blocked through the tubing 30 when the insert 50b is mounted in the latter.

[0139] As seen in figures 9 to 11, the main body 12 of the valve 10 includes a second annular rib 88 which extends circularly around each inlet mouth 32 of the tubing 30 of the pair 86 of tubing 30.

[0140] More particularly, each second annular rib 88 extends circumferentially and coaxially around each inlet 32 ​​and in such a way that it is arranged radially between the outer circumference of the inlet 32 ​​and the inner lateral face 48 of the associated annular portion 38, as seen in [Fig.10] and 11.

[0141] It is then understood that each second annular rib 88 extends axially from a radial thickness of the tubing 30.

[0142] Moreover, and as particularly visible in [Fig. 11], the first annular rib 36 and the second annular rib 88 are axially offset from each other so that the second annular rib 88 extends axially between the inlet mouth 32 of the tubing 30 and the first annular rib 36.

[0143] A third example of the insert 50, 50c will now be described in relation to [Fig.11].

[0144] The insert 50c according to this third example, includes the internal tip 54 which delimits the fluid passage channel 52 and the annular structure 58 comprising only the radial extension 62 and through which the fluid passage channel 52 extends.

[0145] It is understood that in this third example of the insert 50c, its annular structure is devoid of the set of overthicknesses 64.

[0146] According to this third example of the insert 50c, the radial extension 62 extends radially in such a way that it rests on the second annular rib 88, as seen in [Fig.11].

[0147] Thus, it is understood that the annular structure 58 of the insert 50c according to the third embodiment has a diameter smaller than the annular structure 58 of the inserts 50a, 50b according to the first and second examples visible in [Fig.10],

[0148] It is also understood that the absence of the set of overthicknesses 64 allows the radial extension 62 to approach axially the second annular rib 88 and in such a way that it rests on the latter.

[0149] Thus, the contact between the radial extension 62 of the insert 50c and the second annular rib 88 allows a welding action to be carried out so as to secure the inserts 50c according to the third embodiment on the main body 12 and in the tubes 30.

[0150] Furthermore, according to this embodiment of the insert 50c, the internal tip 54 includes an annular notch 102 in which the peripheral wall 72 of the fluidic sealing element 70 is housed.

[0151] The sealing lip 74 also extends to the end of the peripheral wall and in such a way that it is in contact with the plug 16 as described previously.

[0152] It should also be considered that, as with the first and second examples of the insert 50a, 50b, the neck of the internal tip of the insert 50c according to the third example has a concave shape and that the sealing lip has a complementary concave shape, as described previously.

[0153] As can be seen in figures 9 to 11, the main body 12 of the valve 10 includes a third rib 90 which extends around the periphery of each pair 86 of tubing 30.

[0154] More precisely, the third rib 90 extends circumferentially around the first annular ribs 36 of the tubing 30 of the pair 86 of tubing 30.

[0155] It is then understood that only one third rib 90 extends simultaneously around the first annular ribs 36 of the pair 86 of tubing 30.

[0156] Thus, it is understood that the third rib 90 has an oblong shape in a radial plane considering the second axes R2 of revolution of the pair 86 of tubing 30.

[0157] As seen in the example in [Fig. 11], the valve 10 includes a fluidic connection piece 92.

[0158] More particularly, the fluidic connecting piece 92 includes a fluidic link channel 94 extended by a connecting skirt 96 configured to overlap the tubes 30 of the pair 86 of tubes 30.

[0159] Thus, the connecting skirt 96 has an oblong shape.

[0160] More precisely, the connecting skirt 96 includes a side wall 98 which extends axially, considering the second axes R2 of revolution of the tubes 30 of the pair 86, and in such a way that it fits between the first annular rib 36 and the second annular rib 88.

[0161] Still visible in [Fig.1 1], a connecting wall 100 extends radially from the side wall 98 of the connecting skirt 96 and in such a way that it extends in overlap at least of the third rib 90 when the fluidic connecting piece 92 is mounted on the pair 86 of tubing 30.

[0162] More precisely, the connecting wall 100 extends radially from the outer periphery of the lateral wall 98 such that it is in contact with the third rib 90 when the fluidic connection piece 92 is installed over the pair 86 of tubing 36.

[0163] Thus, it is understood that the welding of the fluidic connection piece 92 onto the main body 12 of the valve 10 is carried out via the third rib 90.

[0164] Such a weld of the fluidic connecting piece 92 on the third rib 90 ensures the leak-proof connection between said fluidic connecting piece 92 and the main body 12 of the valve 10.

[0165] It is then understood that the inserts 50c according to the third example which are integral with the second annular ribs 88 associated with the pair 86 of tubing 30, allow the positioning of the fluidic connecting piece 92 so that the fluid circulating through their fluidic passage channel 52 opens into the volume delimited by the connecting skirt 92 to end up in the fluidic linking channel 94 of the fluidic connecting piece 92.

[0166] As seen in [Fig.8], according to this example of the valve 10, the upper axial opening 80 receives an insert 50a according to the first example.

[0167] Thus, it is understood that the plug 16 according to this example of the valve 10 is configured to allow the fluidic connection between the different tubing and according to the type of insert 50a, 50b, 50c used.

[0168] We thus take advantage of the multi-way valve as just described according to the different examples, in that it offers optimal modularity for a user by allowing with the same main body and via its set of ribs, the installation of inserts of different shape and function, while guaranteeing the sealing of said multi-way valve.

[0169] Moreover, the structure of the sealing elements as just described makes it possible to ensure their correct angular position relative to the plug and the inserts while improving their retention within the multi-way valve.
