Abstract

The invention relates to a jet regulator ( 1 ) having an annular or sleeve-shaped jet regulator housing ( 2 ), on the outlet end side of which there is held an outlet disc ( 3 ) which can be inserted into the jet regulator housing ( 2 ), which ( 3 ) has a perforated, grid and/or mesh structure with throughflow openings ( 5 ), wherein the outlet disc ( 3 ) bears a manually deformable dimensionally elastic plastics lining ( 4 ), and wherein the plastics lining ( 4 ) is of pot-shaped design. In order to reduce the production expenditure, it is provided according to the invention that the plastics lining ( 4 ), with an upwardly drawn circumferential wall ( 16 ) of its pot shape, provides sealing between the outer circumference of the outlet disc ( 3 ) and the housing inner circumference of the jet regulator housing ( 2 ).

First claim

What is claimed is:

Jet regulator ( 1 , 100 , 101 ) having a ring-shaped or sleeve-shaped jet regulator housing ( 2 ) in which there is provided a jet splitter ( 10 ) dividing inflowing water into a multiplicity of individual jets, and having a manually deformable, dimensionally elastic plastic lining ( 4 ) provided on the outlet end side of the jet regulator housing ( 2 ), said manually deformable dimensionally elastic plastic lining ( 4 ) is cup-shaped and comprises a raised circumferential wall ( 16 ), which seals against an inner circumference of the jet regulator housing ( 2 ), on the outlet end side, there is held an outlet disk ( 3 ) which is insertable into the jet regulator housing ( 2 ) and is pivotable therein, the outlet disk ( 3 ) has a perforated, grate and/or mesh structure with throughflow openings ( 5 ), and the outlet disk ( 3 ) bears the manually deformable, dimensionally elastic plastic lining ( 4 ), the raised circumferential wall ( 16 ), provides a seal between the outer circumference of the outlet disk ( 3 ) and the housing inner circumference of the jet regulator housing ( 2 ), and a central cam is integrally formed on the jet splitter ( 10 ) on the outflow side, said cam, during the pivoting of the outlet disk ( 3 ), is supported on the outlet disk ( 3 ) or on a central cam ( 17 ) integrally formed on the outlet disk ( 3 ) on an upstream side and wherein the outlet disk ( 3 ) and the manually deformable dimensionally elastic plastic lining ( 4 ) are held on one another in a manner secure against rotation and have throughflow openings ( 5 , 7 ) merging into each other.

2. The jet regulator ( 100 ) according to claim 1 , wherein the manually deformable dimensionally elastic plastic lining ( 4 ) is held releasably or non-releasably on the outlet disk ( 3 ).

3. The jet regulator according to claim 1 , wherein the manually deformable dimensionally elastic plastic lining ( 4 ) is held in an interlocking manner on the outlet disk ( 3 ).

4. The jet regulator according to claim 3 , wherein the manually deformable dimensionally elastic plastic lining ( 4 ) is held by a free edge region of the raised circumferential wall ( 16 ) thereof, said edge region faces away from a base of the manually deformable dimensionally elastic plastic lining ( 4 ), in an interlocking manner on the outlet disk ( 3 ).

5. The jet regulator according to claim 4 , wherein the free edge region ( 20 ) of the raised circumferential wall ( 16 ), said free edge region faces away from the base, is angled inward in such a manner that said edge region ( 20 ) engages behind the inflow-side circumferential end edge of the outlet disk ( 3 ).

6. The jet regulator according to claim 5 , wherein an insertion part ( 11 ), an inflow-side cup base of which is configured as a jet splitter ( 10 ), is insertable into the jet regulator housing ( 2 ).

7. The jet regulator according to claim 1 , wherein the manually deformable dimensionally elastic plastic lining ( 4 ) has, on a free edge region of the raised circumferential wall ( 16 ) thereof, said edge region faces away from a base of the manually deformable dimensionally elastic plastic lining ( 4 ), on an inner circumferential side, at least one encircling recessed or projecting retaining molding ( 29 ) which interacts with a projecting or recessed retaining molding ( 28 ) on the outer circumference of the outlet disk ( 3 ).

8. The jet regulator according to claim 1 , wherein positioning aids corresponding with each other in pairs are provided on an inner side of the manually deformable dimensionally elastic plastic lining ( 4 ) and on an outer side of the outlet disk ( 3 ).

9. The jet regulator according to claim 1 , wherein the outlet disk ( 3 ), on the outflow-side end side thereof, has at least one connecting pin ( 26 ), which interacts with at least one connecting opening ( 25 ) interacts with at least one connecting on an end side of the manually deformable dimensionally elastic plastic lining ( 4 ) which faces the outlet disk.

10. The jet regulator according to claim 1 , wherein the manually deformable dimensionally elastic plastic lining ( 4 ), on an inflow-side outer circumference thereof, has at least one encircling sealing lip or sealing lug ( 27 ) which seals with/against the inner circumference of the jet regulator housing.

11. The jet regulator according to claim 1 , wherein the outlet disk ( 3 ) and the manually deformable dimensionally elastic plastic lining ( 4 ) are held pivotably with each other in the jet regulator housing ( 2 ), which is configured as a joint socket.

12. The jet regulator according to claim 1 , wherein the outlet disk ( 3 ) and/or the manually deformable dimensionally elastic plastic lining ( 4 ) have a spherical outer circumference, and the pivoting disk formed in this manner is mounted pivotably in a partial region, which is configured as a mating joint socket ( 6 ), on the housing inner circumference of the jet regulator housing ( 2 ).

13. The jet regulator according to claim 12 , wherein the outlet disk ( 3 ) is insertable into the housing interior of the jet regulator housing ( 2 ) through an inflow-side insertion opening as far as the partial region configured as a joint socket ( 6 ).

14. The jet regulator according to claim 1 , wherein the throughflow openings ( 5 , 7 ) of the outlet disk ( 3 ) and of the manually deformable dimensionally elastic plastic lining ( 4 ) are arranged on concentric hole circles.

15. The jet regulator according to claim 14 , wherein the throughflow openings ( 7 ) arranged on at least one hole circle, and on an outer hole circle, are provided in an encircling ring wall ( 8 ) of the manually deformable dimensionally elastic plastic lining ( 4 ).

16. The jet regulator according to claim 14 , wherein an outflow-side partial region of at least one throughflow opening ( 7 ) and of the throughflow openings ( 7 ) arranged on an inner hole circles is provided in a teat projecting over the manually deformable dimensionally elastic plastic lining ( 4 ) or in a projection.

17. The jet regulator according to claim 1 , wherein the throughflow openings ( 7 ) provided in the manually deformable dimensionally elastic plastic lining ( 4 ) taper conically at least over a partial region of the longitudinal extent thereof in the direction of flow thereof.

18. The jet regulator according to claim 1 , wherein the cam ( 17 ) provided on the outlet disk ( 3 ) is supported on the cams of the jet splitter ( 10 ) during the pivoting of the outlet disk ( 3 ).

19. The jet regulator according to claim 1 , wherein an insertion part ( 11 ) inserted into the jet regulator housing ( 2 ) upstream of the outlet disk ( 3 ) on the upstream side is configured as a pivoting stop for the outlet disk ( 3 ) which is configured as a pivoting disk.

20. The jet regulator according to claim 1 , wherein an insertion part ( 11 ) is held in the jet regulator housing ( 2 ) in a releasable manner and in a frictional and/or interlocking manner.

21. The jet regulator according to claim 1 , further comprising a throughflow quantity regulator ( 21 ) connected upstream of the jet regulator ( 1 , 100 , 101 ) on an inflow side, and the throughflow quantity regulator ( 21 ) is held on the jet splitter ( 10 ) in a releasably connected latchable manner.

22. Jet regulator ( 1 , 100 , 101 ) having a ring-shaped or sleeve-shaped jet regulator housing ( 2 ) in which there is provided a jet splitter ( 10 ) dividing inflowing water into a multiplicity of individual j
