Description

Technical Field

[0001] The present invention relates to a sanitary embedded cylindrical part, which has a cylindrical part housing, which can be embedded in the water outlet of a water pipe or a sanitary outlet fitting, and the cylindrical part housing has at least one water inlet and at least one water outlet, wherein the embedded cylindrical part is assembled from at least two components, the at least two components are abutted against and / or connected to each other, and at least two adjacent components of the at least two components are fixed in their relative positions relative to each other in the circumferential direction by an anti-rotation portion, and wherein at least one of the adjacent components is constructed as an embedded component that can be embedded in the cylindrical part housing or as a shell component of a two-piece or multi-piece cylindrical part housing. Background Art

[0002] Jet regulators that can be mounted on the water outlet of a sanitary outlet fitting have been realized. In order to be able to mount such jet regulators on the water outlet of a sanitary outlet fitting in the simplest possible manner, these jet regulators are usually constructed as an insertable cylindrical part, whose cylindrical part housing is screwed into an internal thread provided in the water outlet using an external thread provided on the circumference of the housing, or can be mounted on the water outlet of the outlet fitting by means of a sleeve-shaped outlet part.

[0003] A jet splitter is provided in the cylindrical housing of this jet regulator, which divides the water flowing through into a large number of single jets. These single jets can be mixed with the ambient air inhaled in the mixing zone of the cylindrical housing located downstream of the jet splitter. Then, the single jets inflated like this are decelerated in the rectifier of the jet regulator and formed into uniform, non-splashing and, if necessary, soft-bubble outlet jets. Here, the rectifier located downstream of the jet splitter of this known jet regulator has a plurality of embedded components in succession, and these embedded components respectively include a grid structure, a lattice structure or similar hole structures with a large number of flow-through openings. In order to allow the hole structures arranged in these embedded components to interact with each other, and in order to allow the water jet flowing through one of the flow-through holes of the embedded component on the inlet side to impact on one of the intersection nodes of the hole structure arranged in the embedded component on the outlet side, it can be advantageous or even necessary to accurately align these adjacent embedded components. Therefore, the unique design of this known jet regulator also includes an anti-rotation feature that is intended to secure the relative position of adjacent inserts in the circumferential direction. This anti-rotation feature can, for example, comprise at least one longitudinal groove provided on the inner circumference of the cartridge housing, into which a corresponding anti-rotation projection provided on the insert engages. However, this anti-rotation feature formed by at least one longitudinal groove can make automated installation of such sanitary insert cartridges particularly difficult.

[0004] Other sanitary inserts are also available, which are designed as backflow prevention valves connected in the water supply line or which have flow regulators or flow restrictors instead of or in addition to the jet regulator. Even with sanitary inserts of the type mentioned at the outset, precise positional alignment of adjacent components in the circumferential direction may be desirable or even necessary. Summary of the Invention

[0005] The object is therefore in particular to create a sanitary insert cartridge of the type mentioned at the outset, which is characterized by a positionally precise mounting of adjacent and / or mutually connected components.

[0006] In the case of an insert sleeve of the type mentioned at the outset, the object is achieved according to the invention in particular in that at least one first component of the at least two adjacent components of the insert sleeve has an end toothing of an axially acting anti-rotation device on the end side facing the at least one adjacent second component, the end toothing having teeth, and

[0007] at least one of the teeth engages in a recess provided on at least one adjacent second component,

[0008] and / or

[0009] At least one projection of the anti-rotation portion, which is arranged at an adjacent end side of at least one adjacent second component and is oriented in the longitudinal direction of the housing, engages in a tooth root between adjacent teeth of the end toothing.

[0010] Embedded tubular part according to the present invention has a tubular part housing, which can be connected in the water pipeline or installed on the water outlet of a sanitary outlet fitting. In order to make the embedded tubular part conform to the functional shaping, adjustment, stop against the flow direction or otherwise affect the water flowing through, the tubular part housing has at least one water inlet and at least one drain. Here, the embedded tubular part is installed by at least two components, and the at least two components are abutted against each other or connected to each other. Therefore, at least one first component can be configured as an embedded part or a housing part, which acts in conjunction with at least one adjacent second component, and this second component itself is also configured as a housing part or an embedded part. Therefore, each adjacent component can form an embedded part / embedded part combination, an embedded part / housing part combination or a housing part / housing part combination. To secure these components in their relative circumferential position relative to one another, at least one first component of the at least two components required for mounting the insert sleeve according to the present invention has an end toothing with an axially effective anti-rotation feature on the end facing the at least one adjacent second component. This end toothing has teeth, wherein at least one projection, provided on the adjacent end of the at least one adjacent second component and oriented in the longitudinal direction of the housing, engages in the tooth base between adjacent teeth of the end toothing. Additionally or alternatively, at least one of the teeth provided on the at least one first insert component can engage in a rotationally secure manner in a recess provided on the adjacent second component. Because the anti-rotation feature forming this end toothing of the insert sleeve according to the present invention eliminates the need for outwardly protruding anti-rotation projections or longitudinal grooves provided on the inner circumference, the insert sleeve according to the present invention can be constructed with a smaller housing diameter without, for example, having to reduce the outlet cross-section of the outlet opening provided on the housing end face of the sleeve housing on the outflow side. Due to the reduced diameter requirement, the insert sleeve according to the present invention is characterized by a more favorable ratio of jet diameter to installation diameter. The self-aligning properties of the end teeth, designed as axially acting anti-rotation features, simplify the installation of the insert-type cylindrical element according to the present invention, allowing it to be easily automated. Because the end teeth also compensate for manufacturing tolerances, more precise angular positioning of adjacent components is achieved. This effect can be combined with other contours of these components to simplify the manufacturing effort required to produce the insert-type cylindrical element according to the present invention.

[0011] According to a simple and advantageous embodiment of the invention, it is provided that at least one of the recesses provided on at least one adjacent second component is designed as a groove.

[0012] If the teeth provided on the at least one first component are arranged radially relative to the longitudinal axis of the housing, the rotational locks provided on adjacent components that are designed to complement each other can be brought into the desired rotational position particularly simply and easily.

[0013] If a plurality of projections spaced apart from one another in the circumferential direction are provided at the end side of the at least one second component adjacent to the at least one first component, self-alignment of the adjacent components relative to one another is simplified.

[0014] If the corresponding contour portion of the anti-rotation portion engages in an end engagement portion provided on the at least one first component, which corresponding contour portion is provided at the adjacent end side of the adjacent second component, the advantages achieved by the anti-rotation portion constructed as an axially acting end engagement portion are additionally promoted.

[0015] According to a preferred refinement of the present invention, the at least one first component and the at least one adjacent second component each have axially intermeshing end teeth as anti-rotation features at their adjacent end sides. The teeth on one of the end teeth of the anti-rotation features form projections that engage in the tooth roots of the adjacent end teeth.

[0016] Therefore, in such an embodiment, it is advantageous if the teeth of the first end toothing provided on the at least one first component engage in the tooth roots of the second end toothing of the anti-rotation part which is arranged on at least one adjacent second component of the insertion sleeve and is provided as a counter-contour.

[0017] According to a preferred improvement of the present invention, the improvement is characterized in that the components adjacent to each other are axially aligned, and it is stipulated that the teeth of the end engagement portion arranged on at least one first component and / or at least one adjacent second component rise radially from the inside to the outside and / or the tooth roots descend radially from the inside to the outside.

[0018] In order to be able to provide such an end engagement on a component constructed as an embedded part, according to a preferred embodiment of the present invention, a central axial end or alignment end oriented parallel to the longitudinal axis of the housing is provided on at least one first component constructed as an embedded part, which has a first end engagement on the end side, and at least one protrusion, corresponding contour or second end engagement is provided at an adjacent end side of at least one adjacent second component.

[0019] However, for this purpose, it is also possible to provide a circumferential outer ring on the outer circumference of the first component of the insert cylinder and / or at least one adjacent second component, which has a first or second end toothing at at least one of its end sides.

[0020] In order to be able to align the housing part of the embedded cylindrical part according to the present invention relative to other adjacent housing parts or relative to the embedded part that can be embedded in the housing part, it is advantageous if at least one second component of the embedded cylindrical part is constructed as a housing part of a multi-piece cylindrical part housing and the at least one protrusion, the corresponding contour part or the end engagement part is arranged on the end side edge of the housing part facing the housing interior space.

[0021] In particular, if the end engagement provided on at least one first component does not interact with the end engagement on the at least one second component, and if at least one protrusion is to be provided on the at least one second component instead, it is advantageous if the at least one protrusion is rounded or angularly configured at its free end.

[0022] According to a preferred embodiment of the present invention, the barrel housing has at least one housing opening on the inlet side as a water inlet, and the at least one housing opening can be closed by a second component configured as a jet splitter with a splitter opening, the jet splitter being lockable and, in particular, releasably lockable to the housing inner circumference of the barrel housing. In the housing interior of such a barrel housing formed by at least two housing components that can be locked to each other, additional insert components can be embedded in an equally simple manner. Advantageously, at least one projection oriented parallel to the longitudinal axis of the housing protrudes from the jet splitter, the projection cooperating with an end engagement portion on an adjacent end side edge of an outer ring of an adjacent component configured as an insert component.

[0023] In order that at least one anti-rotation feature forming an end engagement of the insert-type cylindrical element according to the invention is already effective during installation, and in order that the end engagement on at least one first component can engage in a simple manner with a projection, a corresponding contour or an end engagement on an adjacent second component, it is advantageous if the outer ring of at least one of these insert-type parts is slidably guided in the cylindrical element housing along the inner circumference of the housing.

[0024] The installation of the insert cartridge according to the invention is further simplified by providing an annular shoulder on the housing inner circumference of the cartridge housing, which serves as a sliding stop when at least one component designed as an insert part is slid into the housing interior of the cartridge housing.

[0025] According to a preferred embodiment of the invention, at least one projection, oriented parallel to the longitudinal axis of the housing, projects from the collar, said projection projecting into the tooth base between two adjacent teeth of an end toothing provided on the outer ring of an adjacent insert.

[0026] A preferred application example of the present invention provides that the sanitary embedded cylindrical part is configured as a jet regulator or contains a jet regulator. In particular, in such a jet regulator, the embedded parts required for shaping the water flowing through must be installed with precise position relative to each other in the simplest possible way.

DETAILED DESCRIPTION

[0048] exist Figures 1 to 141 shows different embodiments of sanitary embedded cylindrical parts 101, 104, 107, 110, and 112. Each embedded cylindrical part 101, 104, 107, 110, and 112 comprises a cylindrical part housing 2 that can be connected to a water line or embedded in the water outlet of a sanitary outlet fitting. The cylindrical part housing 2 of each of these embedded cylindrical parts 101, 104, 107, 110, and 112 comprises a water inlet 3 arranged at the housing end on the inlet side and a water outlet 4 arranged at the housing end on the outlet side. Each embedded cylindrical part 101, 104, 107, 110, and 112 is assembled from at least two components 5, 6, 7, 8, 9, and 10, at least two of which are in contact with or connected to one another. At least two of the components 5, 6, 7, 8, 9, or 10 required for mounting the insert sleeves 101, 104, 107, 110, and 112 are secured in their relative circumferential position relative to one another by means of a rotational lock. Of the adjacent components 5, 7; 7, 8; 6, 8; 7, 9, and 8, 10 secured by the rotational lock 1, at least one first component has an end toothing 11 on its end facing at least one adjacent second component as an axially effective rotational lock, comprising teeth 12 arranged radially relative to the longitudinal axis of the housing. A corresponding projection, provided on the adjacent end side of the at least one adjacent second component and oriented in the longitudinal direction of the housing, engages at least one tooth root 13 between adjacent teeth 12 of the end toothing 11. The projection provided on the adjacent end side of the at least one adjacent second component can be configured as a pin-shaped projection 14. It is also possible that a corresponding profile 15 is provided on the adjacent end side of at least one adjacent second component, the projection of which engages in the end engagement portion 11 of the adjacent first component. In the embodiment shown here, the corresponding profile 15 is also configured as an end engagement portion, so that the end engagement portion 11 of the anti-rotation part 1, which is provided on the corresponding first component, and the corresponding profile 15, which is provided on the adjacent end side of the adjacent second component and is also configured as an end engagement portion, engage with each other, so that the teeth 12 of the first end engagement portion 11 provided on the at least one first component engage in the tooth roots 13 of the second end engagement portion arranged on the at least one adjacent second component of the embedded cylindrical part and serving as the corresponding profile 15.

[0049] The teeth 12 of the first and / or second end teeth 11 , 15 form projections which each engage in a corresponding tooth base 13 of the adjacent component.

[0050] In the embodiment shown here (in which the end engagement portion 11 of the first component acts together with a corresponding contour portion 15 on an adjacent second component, which is also constructed as an end engagement portion), the teeth 12 of the end engagement portion provided on at least one first component and / or at least one adjacent second component rise radially from the inside to the outside, and, in addition or alternatively, the tooth roots can descend radially from the inside to the outside relative to this, so that these paired components are always arranged coaxially with each other and are independent and angularly correct to each other in corresponding pitches and / or appropriate tooth slopes / tooth tips.

[0051] Possible, but not shown here, is an embodiment in which a central axial end or alignment end oriented parallel to the longitudinal axis of the housing is provided on at least one first component configured as an embedded part and / or on at least one adjacent second component, which carries a first end engagement portion on the end side, and at least one protrusion, corresponding contour portion or second end engagement portion is provided on the adjacent end side of at least one adjacent second component.

[0052] In contrast, in Figures 1 to 14 As can be seen in FIG, a circumferential outer ring 16 is arranged on the outer circumference of the first components 7 , 8 designed as an insert, which outer ring has one of the end teeth 11 , 15 of the rotation protection 1 on at least one of its end faces.

[0053] exist Figures 1 to 14 The illustrated insert cartridges 101, 104, 107, 110, and 112 have a cartridge housing 2, which, as shown here, is constructed in two parts or can also be constructed in multiple parts. The cartridge housing 2 of the illustrated insert cartridges 101, 104, 107, 110, and 112 has an inlet-side housing part 5 or 9 and an outlet-side housing part 6 or 10. The illustrated insert cartridges 101, 104, 107, 110, and 112 are constructed as jet regulators, and in particular as pneumatic jet regulators. Figures 1 to 14The jet regulator shown has a jet splitter 19 that splits the water flowing in through the water supply line into a large number of individual jets. The jet splitter 19, which is configured as an orifice plate with multiple splitter openings 20, is embedded in the cylindrical parts 101, 104, 107, 110, and 112. The water flowing into the jet regulator is split into individual jets in the splitter openings 20 of the orifice plate and accelerated to generate a negative pressure on the outflow side of the orifice plate. Ambient air is drawn into the cylindrical part housing 2 by this negative pressure and mixes with the individual jets in a mixing zone arranged on the outflow side of the orifice plate. A rectifier is provided downstream of the jet splitter 19, which is configured as an orifice plate, embedded in the cylindrical parts 101, 104, 107, 110, and 112 in the direction of flow. The rectifier is formed by the embedded components 7 and 8. These embedded parts 7, 8 have a grid structure, a lattice structure or a similar hole structure, which is formed by a plurality of groups of webs 22, 23 that intersect with each other at intersection nodes 21. The grid structure of the embedded parts 7, 8 shown here is formed by a group of concentric webs 22, which intersect with a group of radial webs 23 at the intersection node 21. The individual components of the embedded cylindrical parts 101, 104, 107, 110 and 112 can be aligned with each other so that the single jet generated in the orifice plate hits the intersection node 21 of the first embedded part 7 adjacent to the jet splitter 19. At these intersection nodes 19 of the embedded part 7 on the inlet side, the single jets that are also separated and mixed with the ambient air then hit the intersection nodes 21 of the second embedded part 8 located downstream in the through-flow direction, wherein these intersection nodes 21 of the grid structure arranged on the second embedded part 8 are aligned with the through-flow openings on the first embedded part 7 on the inlet side. Figures 1 to 14 In the illustrated embedded cylindrical parts 101, 104, 107 and 112, the jet splitter 19 configured as a perforated plate is integrally formed on the inlet side housing part 5, which also carries the inlet side partial area of ​​the housing peripheral wall. Figure 10 The cylindrical part housing 2 for the insert cylindrical part 110 shown in FIG has a housing part 9 forming the inlet-side housing end and configured as a perforated plate or jet splitter, which can be inserted into a sleeve opening of a second sleeve-shaped housing part 10 arranged on the inlet side, wherein the housing parts 9, 10 can be releasably locked to each other. For this purpose, a latching projection 24 is formed circumferentially on the outer circumference of the housing part 9 configured as a perforated plate or jet splitter 19, which latches into a latching recess 25 on the inner circumference of the sleeve-shaped housing part 10. A grid-like hole structure, shown here only as an example for any outlet structure, is provided on the outlet end of the housing parts 6, 10, consisting of webs 17, 18 arranged at right angles to each other, which define an outlet opening aligned with the through-flow opening of the insert part 8, in particular on the outlet side. In order to fix the relative positions of adjacent components along the circumferential direction of the housing, corresponding anti-rotation portions 1 are provided between the adjacent components 6 , 8 ; 8 , 10 .

[0054] The insert components 7, 8, which are configured as insert cylinders 101, 104, 107, 110, and 112 of the jet regulator, each have an end toothing 11 on both end sides of their outer ring 16. The end sides of the outer ring 16 facing the respective adjacent insert components 8, 7 fix the relative position of the insert components with respect to one another, while the end teeth provided on the inflow-side end edge of the insert component 7 or on the outflow-side end edge of the insert component 8 interact with pin-shaped projections 14 on the inflow-side housing components 5, 9 or with corresponding contours 15 on the inner circumference of the outflow-side housing component 6.

[0055] from Figures 1 to 3 and Figures 4 to 6 The comparison clearly shows that the pin-shaped protrusion 14 protruding from the housing part 5 on the inflow side of the embedded cylindrical member 104 is only provided according to Figures 1 to 3 The half of the pin-shaped protrusion in the embedded cylindrical member 101. Figures 1 to 14 A comparison clearly shows that the pin-shaped projections 14 on the inlet-side housing part 5 or the outlet-side housing part 10 can be rounded at their free ends, but can also be square or arrow-shaped.

[0056] Figure 15 and 16 Three adjacent components 19, 7, 8 are shown, which are joined together to form a single assembly. One of these components on the inlet side is designed as a perforated plate which also serves as a jet splitter 19, while the two downstream components on the outlet side are also designed as inserts 7, 8, which have end teeth 11, 15 on the inlet-side and outlet-side end edges of their outer ring 16. Figure 15 、 16 As is clear from Figures 18 and 18 , the teeth 12 of the end toothing 11 provided on the adjacent first component 7 each engage in a recess 27 provided on the outflow-side end surface circumferential edge of the jet splitter 19 serving as the second component and designed here as a groove.

[0057] Figure 15 and 16 The installation parts 7 , 8 of the illustrated component assembly also have a lattice structure, a mesh structure or a similar hole structure, which is formed by groups of webs 22 , 23 that cross one another at intersection nodes 21 . Figure 15 and 16The lattice structure of the insert parts 7 and 8 shown in FIG is also formed by a set of concentric webs 22, which intersect at a set of radial webs 23 at a cross-junction 21. In order to align the different components 19, 7, and 8 with one another, so that the individual jets formed in the jet splitter 19 impinge on the cross-junction 21 of the first insert part 7 adjacent to the jet splitter 19 and thus precisely on the desired contour of the downstream component, and in order to align the cross-junction 21 of the lattice structure provided on the second insert part 8 with the through-flow openings on the first insert part 7 on the inlet side, rotation locks are provided between the components 19, 7, and 8.

[0058] from Figure 17 、 18 A comparative observation with 19 clearly shows that, in addition or alternatively, a protrusion 14 can also protrude from the end side circumferential edge of the jet splitter 19 serving as the second component on the outflow side, which engages in at least one tooth root 13 between adjacent teeth 12 of the end engagement portion 11 on the adjacent embedded part 7 arranged downstream.

[0059] It goes without saying that adjacent housing parts and / or components of the insert sleeve can be arranged in a rotationally fixed manner relative to one another by means of identical or different orientation elements.
