Abstract

In a jet regulator (101, 104, 107, 110, 112), a housing (2) and an insert part (7, 8) which can be inserted into the jet regulator have complementary engagement parts which engage with one another when the jet regulator is assembled, so that the housing (2) and the insert part (7, 8) are prevented from rotating relative to one another.

Description

Jet regulator with component and anti-rotation part

Technical Field

The invention relates to a sanitary fitting cartridge having a cartridge housing which can be fitted into a water outlet of a water line or a sanitary outlet fitting and which has at least one water inlet and at least one water outlet, wherein the fitting cartridge is assembled from at least two components which rest against one another and/or are connected to one another and at least two adjacent components of which are fixed in their relative position in the circumferential direction with respect to one another by means of rotation-preventing means, and wherein at least one of the adjacent components is designed as a fitting part which can be fitted into the cartridge housing or as a housing part of a two-part or multi-part cartridge housing.

Background

A jet regulator has been realized which can be mounted on the water outlet of a sanitary outlet fitting. In order to be able to mount such jet regulators on the water outlet of the sanitary outlet fitting in the simplest possible manner, these jet regulators are usually designed as a fitting cartridge, the cartridge housing of which is screwed into an internal thread provided in the water outlet by means of an external thread provided on the housing circumference or can be mounted on the water outlet of the outlet fitting by means of a sleeve-like outlet part.

In the cartridge housing of such jet regulators, a jet splitter is provided which splits the water flowing through into a plurality of individual jets. These single jets can be mixed with the intake ambient air in a mixing zone of the cartridge housing downstream of the jet splitter. The single jet thus aerated is then decelerated in the rectifier of the jet regulator and formed into a uniform, splash-free and, if necessary, also bubble-soft outlet jet. The flow straightener of this known jet regulator downstream of the jet splitter has a plurality of successive insert parts, each of which comprises a grid structure, a mesh structure or a similar hole structure with a multiplicity of flow-through openings. In order to be able to interact the hole structures arranged in the insert parts and in order to impinge a water jet flowing through one of the flow-through holes of the insert part on the inflow side onto one of the intersection nodes of the hole structures arranged in the insert part on the outflow side, it can be advantageous or even necessary to align the insert parts adjacent to one another in a positionally precise manner. The individual design of the known jet regulator therefore also has a rotation prevention part which is intended to fix the relative position of the adjacent insert parts in relation to one another in the circumferential direction. The rotation prevention means can have, for example, at least one longitudinal groove arranged on the inner circumference of the cartridge housing, in which at least one rotation prevention projection arranged on the insert part engages. However, such an anti-rotation part formed by at least one longitudinal groove can make particularly automated mounting of such a sanitary installation cartridge extremely difficult.

Other sanitary insert cylinders are also realized, which are designed as backflow-preventing valves intermediately connected in the water supply line or have flow regulators or flow restrictors instead of or in addition to jet regulators. Even in the case of such a sanitary installation cartridge of the type mentioned at the outset, it may be desirable or even necessary for the positions of adjacent components in the circumferential direction to be precisely aligned.

Disclosure of Invention

The object is therefore in particular to provide a sanitary installation cartridge of the type mentioned at the outset, which is distinguished by the fact that adjacent and/or interconnected components are installed in a positionally precise manner.

In the case of a fitting cylinder of the type mentioned at the outset, the solution according to the invention for this object is in particular that at least one first component of at least two adjacent components of the fitting cylinder has an end toothing of an axially acting rotation prevention part at the end side facing at least one adjacent second component, which end toothing has teeth, and that

-at least one of the teeth engages into a recess provided at least one adjacent second member,

and/or

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

The insert cartridge according to the invention has a cartridge housing which can be connected intermediately into the water line or mounted on the water outlet of the sanitary outlet fitting. In order to be able to shape, adjust, stop or otherwise influence the water flowing through the insertion cylinder in a functional manner counter to the direction of flow through, the cylinder housing has at least one water inlet and at least one water outlet. The installation cylinder is thereby assembled from at least two components, which rest against one another or are connected to one another. Thus, the at least one first component can be designed, for example, as a fitting part or housing part, which interacts with at least one adjacent second component, which is also designed as a housing part or fitting part. Each adjacent component can thus form a fitted part/fitted part combination, a fitted part/housing part combination or a housing part/housing part combination. In order to fix these components in the relative position with respect to one another in the circumferential direction, at least one first component of the at least two components required for mounting the installation cylinder according to the invention has, at the end side facing the at least one adjacent second component, an end toothing of an axially acting rotation prevention part having teeth, wherein at least one projection provided at the adjacent end side of the at least one adjacent second component and oriented in the housing longitudinal direction engages into the tooth root between the adjacent teeth of the end toothing. Additionally or alternatively, at least one of the teeth provided on at least one first fitting part may engage in a recess provided on an adjacent second component against rotation. Since the rotation prevention part of the insertion cylinder according to the invention, which forms such an end engagement, makes no longer necessary an outwardly projecting rotation prevention projection or a longitudinal groove provided on the inner circumference, the insertion cylinder according to the invention can also be constructed with a smaller housing diameter without the outlet cross section of the outlet opening, for example, provided on the housing end face on the outflow side of the cylinder housing, therefore having to be reduced. Due to the reduced diameter requirement, the insert cylinder according to the invention is characterized by a more favorable ratio of jet diameter to insert diameter. Due to the self-aligning properties of the end engagement of the rotation prevention part configured to act axially, the mounting of the installation cartridge according to the invention is simplified such that it can also be automated in a simple manner. Since the end engagement also compensates for manufacturing tolerances, a more precise angular positioning of the components adjacent to one another is achieved. This effect can be used in combination with other profiles of these components to simplify the manufacturing effort required to manufacture the installation cylinder according to the invention.

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.

The anti-rotation portions provided on adjacent components that are configured complementary to one another are particularly simple and easy to position in the desired rotational position if the teeth provided on the at least one first component are arranged radially with respect to the housing longitudinal axis.

The self-alignment of adjacent components with respect to one another is simplified 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.

The advantages achieved by the anti-rotation part configured as an axially acting end engagement are additionally also promoted if a corresponding profile of the anti-rotation part engages into an end engagement provided on the at least one first component, which is provided at an adjacent end side of an adjacent second component.

In this case, according to a preferred further development of the invention, it is provided that the at least one first component and the at least one adjacent second component each have, as rotation prevention means, on their mutually adjacent end sides, end engagement means which axially engage with one another. Here, the teeth at one of the end meshes of the anti-rotation portion form projections which engage into the tooth roots of the adjacent end meshes.

In such an embodiment, it is therefore advantageous if the teeth of the first end toothing provided on the at least one first component engage into the teeth roots of the second end toothing of the rotation prevention section which is arranged on the at least one adjacent second component of the installation cylinder and is provided as a corresponding contour.

According to a preferred development of the invention, the development is characterized in that the components adjacent to one another are axially aligned, it being provided that: the teeth of the end toothing provided 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 roots of the teeth fall radially from the inside to the outside.

In order to be able to provide such an end engagement on the component designed as a built-in part, it is provided according to an advantageous embodiment of the invention that a central shaft end or alignment end, which is oriented parallel to the housing longitudinal axis, is provided on the at least one first component designed as a built-in part, which has a first end engagement on the end side, and at least one projection, corresponding contour or second end engagement is provided on the adjacent end side of at least one adjacent second component.

For this purpose, however, it is also possible to provide a circumferential outer ring on the outer circumference of the first and/or at least one adjacent second part of the installation cylinder, which is designed as an installation part, said outer ring having a first or second end engagement on at least one of its end sides.

In order to be able to align the housing part of the installation cylinder according to the invention relative to another adjacent housing part or relative to an installation part that can be installed in the housing part, it is advantageous if the at least one second part of the installation cylinder is designed as a housing part of a multi-part cylinder housing and the at least one projection, for the contour or the end engagement is arranged on an end-side edge of the housing part facing the housing interior.

In particular, if the end engagement provided on the at least one first component does not interact with the end engagement on the at least one second component, and if instead at least one projection is to be provided on the at least one second component, it is advantageous if the at least one projection is rounded or angled at its free end.

According to a preferred embodiment of the invention, it is provided that the cartridge housing has at least one housing opening on the inflow side as a water inlet and that the at least one housing opening can be closed by a second component designed as a jet splitter having a splitter opening, which can be locked and in particular releasably locked on the housing inner circumference of the cartridge housing. In the case interior of such a cylinder case, which is formed by at least two case parts that can be locked to one another, further fitting parts can be fitted in an equally simple manner. Advantageously, at least one projection oriented parallel to the longitudinal axis of the housing projects at the jet splitter, said projection interacting with an end engagement on an adjacent end side edge of the outer ring of an adjacent component designed as a mounting part.

In order for the at least one anti-rotation portion of the fitted cylinder according to the invention, which forms the end engagement portion, to be active already during mounting and for the end engagement portion on at least one first component to engage in a simple manner with a projection, a corresponding profile or an end engagement portion on an adjacent second component, it is advantageous if the outer ring of at least one of the fitted parts is slidably guided in the cylinder housing along the housing inner circumference.

The fitting cylinder according to the invention is also simplified in that an annular shoulder is provided on the housing inner circumference of the cylinder housing, which serves as a sliding stop when at least one component designed as a fitting part slides into the housing interior of the cylinder housing.

In this case, according to a preferred embodiment of the invention, it is provided that at least one projection of the shaft oriented parallel to the longitudinal axis of the housing projects at the collar shoulder, said projection projecting into the tooth root between two adjacent teeth of the end toothing provided on the outer ring of the adjacent insert part.

A preferred application example of the invention provides that the sanitary installation cylinder is designed as or contains a jet regulator. In particular in such jet regulators, the installation of the insert parts required for shaping the water flowing through must be carried out in a positionally precise manner relative to one another in the simplest possible manner.

Detailed Description

In fig. 1 to 14

different embodiments

101, 104, 107, 110 and 112 of the sanitary insertion cartridge are shown. The

insert cylinders

101, 104, 107, 110 and 112 have a cylinder housing 2 which can be connected intermediately into the water line or inserted into the outlet of the sanitary outlet fitting. The cartridge housing 2 of these

insert cartridges

101, 104, 107, 110 and 112 has a water inlet 3 arranged here on the housing end side on the inflow side and a water outlet 4 arranged on the housing end side on the outflow side. The

installation cylinders

101, 104, 107, 110 and 112 are assembled from at least two

components

5, 6, 7, 8, 9, 10, at least two of which rest against one another or are connected to one another. Here, at least two of the

members

5, 6, 7, 8, 9, or 10 required for mounting the

fitting cylinders

101, 104, 107, 110, and 112 are fixed by the rotation preventing portions in their relative positions in the circumferential direction with respect to each other.

Members

5, 7 adjacent to each other and fixed by the rotation preventing portion 1; 7. 8; 6. 8; 7. 9 and 8, 10, at least one first component has, on its end side facing at least one adjacent second component, an end toothing 11 as an axially acting rotation prevention means with teeth 12 arranged radially to the housing longitudinal axis. In at least one root 13 between adjacent teeth 12 of the end toothing 11, a respective projection which is provided on the adjacent end side of at least one adjacent second component and which is oriented in the longitudinal direction of the housing engages. The projection provided on the adjacent end side of at least one adjacent second component may be configured as a pin-like projection 14. It is also possible that on the adjacent end side of at least one adjacent second component a counter profile 15 is provided, the projection of which engages into the end engagement 11 of the adjacent first component. In the exemplary embodiment shown here, this counter-contour 15 is also designed as an end toothing, so that the end toothing 11 of the rotation prevention part 1, which is provided on the respective first component on the one hand, and the counter-contour 15, which is provided on the adjacent end side of the adjacent second component and is also designed as an end toothing, mesh with one another, so that the teeth 12 of the first end toothing 11 provided on the at least one first component engage into the tooth root 13, which is arranged on the at least one adjacent second component of the installation cylinder and serves as a second end toothing of the counter-contour 15.

The teeth 12 of the first and/or

second end toothing

11, 15 form projections which engage in corresponding tooth roots 13 of adjacent components.

In the exemplary embodiment shown here (in which the end toothing 11 of a first component interacts with a corresponding profile 15 on an adjacent second component, which is also designed as an end toothing), the teeth 12 of the end toothing provided on at least one first component and/or on at least one adjacent second component rise radially from the inside to the outside, and in addition or alternatively the tooth roots can also fall radially from the inside to the outside in contrast thereto, so that these components which are assigned to one another in pairs are also always arranged coaxially to one another and are independent of one another in the respective pitch and/or the appropriate tooth pitch/tooth point and are angled correctly relative to one another.

It is possible, but not shown here, to provide an embodiment in which a central axial or alignment end, whose axis is oriented parallel to the housing longitudinal axis, is provided on at least one first component designed as a fitting part and/or on at least one adjacent second component, which carries a first end engagement on the end side, and at least one projection, counter contour or second end engagement is provided on the adjacent end side of at least one adjacent second component.

In contrast, it can be seen in fig. 1 to 14 that a circumferential outer ring 16 is provided on the outer circumference of the

first component

7, 8, which is designed as a fitting part, which outer ring has one of the

end engagement portions

11, 15 of the rotation prevention part 1 on at least one of its end sides.

The

insert cylinders

101, 104, 107, 110 and 112 shown in fig. 1 to 14 have a cylinder housing 2 which, as shown here, is of two-part design or possibly also of multiple-part design. The cartridge housing 2 of the

insertion cylinders

101, 104, 107, 110 and 112 shown here has an inflow-

side housing part

5 or 9 and an outflow-

side housing part

6 or 10. The

installation cylinders

101, 104, 107, 110 and 112 shown here are designed as jet regulators and in particular as aerated jet regulators. The jet regulator shown in fig. 1 to 14 has a jet splitter 19 which splits the water flowing in through the water supply line into a plurality of individual jets. The jet splitter 19 of the

insert cylinders

101, 104, 107, 110 and 112 is designed here as a perforated plate with a plurality of splitter openings 20. The water flowing to the jet regulator is divided into individual jets in the splitter openings 20 of the perforated plate and accelerated in such a way that a negative pressure is generated on the outflow side of the perforated plate. Ambient air is drawn into the cartridge housing 2 by this underpressure, which mixes with the single jet in a mixing zone arranged on the outflow side of the perforated plate. Downstream of the jet splitter 19, which is designed as a perforated plate, of the

insert cylinders

101, 104, 107, 110 and 112 in the flow direction, a flow straightener is provided, which is formed by the

insert parts

7, 8. These insert

parts

7, 8 have a grid structure, a mesh structure or a similar hole structure, which is formed by groups of

webs

22, 23 which cross each other at crossing nodes 21. The lattice structure of the

installation parts

7, 8 shown here is formed by a set of concentric webs 22 which intersect a set of radial webs 23 at the intersection nodes 21. The individual components of the

insert cylinders

101, 104, 107, 110 and 112 can be aligned with one another so that the individual jets produced in the perforated plate impinge on the intersection nodes 21 of the first insert part 7 adjacent to this jet splitter 19. The individual jets which are additionally separated and mixed with the ambient air at the intersection nodes 19 of the insert part 7 on the inflow side then impinge on the intersection nodes 21 of the second insert part 8 located downstream in the flow direction, wherein the intersection nodes 21 of the grid structure arranged on the second insert part 8 are aligned with the flow openings on the first insert part 7 on the inflow side. In the insert-in

tubular parts

101, 104, 107 and 112 shown in fig. 1 to 14, the jet splitter 19 in the form of a perforated plate is integrally formed on the housing part 5 on the inflow side, which also carries a partial region on the inflow side of the housing circumferential wall, while the tubular part housing 2 of the insert-in tubular part 110 shown in fig. 10 has a housing part 9, which forms the housing end side on the inflow side and is in the form of a perforated plate or jet splitter, which can be inserted into a sleeve opening provided on the inflow side of the sleeve-like second housing part 10, wherein the

housing parts

9, 10 can be releasably locked to one another. For this purpose, a latching projection 24, which latches into a latching recess 25 on the inner circumference of the sleeve-shaped housing part 10, is formed circumferentially on the outer circumference of the housing part 9 in the form of a perforated plate or jet splitter 19. On the outlet-side end of the

housing parts

6, 10, a grid-like hole structure is provided, which is formed by

webs

17, 18 arranged at right angles to one another and which are shown here only by way of example for any outlet structure, said webs defining outlet openings which are aligned with the through-flow openings of the insert part 8, in particular on the outlet side. In order to fix the relative positions of the respective adjacent members in the housing circumferential direction, the

adjacent members

6, 8; 8. 10 between which the respective anti-rotation portion 1 is arranged.

The

insert parts

7, 8 of the

insert cylinders

101, 104, 107, 110 and 112 designed as jet regulators each have an end engagement 11 on both end sides of their outer ring 16. The end sides of the outer ring 16 facing the adjacent

fitting parts

8, 7 fix the relative position of the fitting parts with respect to each other, while the end engagement portions provided on the end side edges on the inflow side of the fitting parts 7 or on the end side edges on the outflow side of the fitting parts 8 cooperate with the pin-shaped projections 14 on the inflow-

side housing parts

5, 9 or with the corresponding contour portions 15 on the inner periphery of the outflow-side housing part 6.

As is clear from a comparison of fig. 1 to 3 and 4 to 6, the pin-shaped projections 14 which project out of the housing part 5 on the inflow side of the insertion cylinder 104 are provided only half as much as the pin-shaped projections in the insertion cylinder 101 according to fig. 1 to 3. As is clear from a comparison of fig. 1 to 14, the pin-shaped projections 14 on the inflow-side housing part 5 or on the outflow-side housing part 10 can be rounded, but can also be of a square or arrow-shaped configuration at their free ends.

Fig. 15 and 16 show three

adjacent components

19, 7, 8 joined to one another in an assembly, of which one component on the inflow side is designed as a perforated plate which also serves as a jet splitter 19, while the two components on the outflow side downstream thereof are also designed as

insert parts

7, 8 which have

end engagements

11, 15 on the end-side edges of the inflow and outflow sides of their outer ring 16. As is clear from a joint observation of fig. 15, 16 and 18, the teeth 12 of the end toothing 11, which are provided on the adjacent first component 7, each engage in a recess 27, which is provided on the end-face circumferential edge on the outflow side of the jet splitter 19 serving as the second component and is configured here as a groove.

The

insert parts

7, 8 of the component assembly shown in fig. 15 and 16 also have a lattice structure, a lattice structure or a similar pore structure, which is formed by groups of

webs

22, 23 which cross one another at crossing nodes 21. The lattice structure of the

insert parts

7, 8 shown in fig. 15 and 16 is also formed by a set of concentric webs 22 which intersect a set of radial webs 23 at the intersection nodes 21. In order to align the

different components

19, 7, 8 with one another such that the individual jets formed in the jet splitter 19 impinge on the intersection nodes 21 of the first insert part 7 adjacent to this jet splitter 19 and thus precisely on the desired contour of the downstream component, and in order to align the intersection nodes 21 of the grille structure provided on the second insert part 8 with the flow-through openings on the first insert part 7 on the inflow side, anti-rotation means are provided between the

components

19, 7 and 8.

As is clear from a comparative observation of fig. 17, 18 and 19, a projection 14 can also or alternatively protrude from the outflow-side circumferential edge of the jet splitter 19 serving as the second component, which projection engages in at least one tooth root 13 between adjacent teeth 12 of the end toothing 11 provided on the downstream adjacent insert part 7.

It goes without saying that adjacent housing parts and/or components of the installation cylinder can be arranged rotationally fixed relative to one another by means of uniform or different orientation elements.
