Abstract

A sanitary fitted element ( 1 ) which can be inserted into the water outlet of a sanitary outlet fitting and is held releasably there. A characteristic feature of the fitted element ( 1 ) according to the invention is that said fitted element has an adjusting device for changing the clear sectional area of flow of the fitted element ( 1 ) and/or the discharge rate, which adjusting device is actuable via at least one control element ( 8 ) which is arranged actuably on the inflow side of the fitted element ( 1 ) and/or on the outflow side thereof. The fitted element ( 1 ) according to the invention can be used in a versatile manner in order to reduce the outlay on production and stock.

First claim

The invention claimed is:

1. A sanitary installation element ( 1 , 2 , 3 , 4 , 5 , 6 , 7 ) which can be inserted into a water outlet of a sanitary outlet fitting, comprising an adjustment device for varying at least one of a clear throughflow cross section of the installation element or a volume flow, said adjustment device is actuatable by at least one operating element ( 8 ) arranged such for actuation on at least one of an inflow side of the installation element or on an outflow side of said installation element, wherein the adjustment device has a regulating element ( 9 ) and, interacting therewith, an adjustment element ( 10 ), a relative position of which can be varied by the at least one operating element ( 8 ) in order to vary the throughflow cross section or a throughflow rate, the at least one operating element ( 8 ) is mounted so as to be rotatable but immovable in a longitudinal direction, the adjustment element is guided so as to be displaceable in the longitudinal direction and rotationally fixed, and a rotational movement at said operating element ( 8 ) is convertible into a longitudinal movement of the adjustment element, wherein the adjustment device is in the form of a throughflow rate regulator ( 18 ) which has an annular throttle body ( 19 ) comprised of elastic material that delimits a control gap ( 22 ) between itself and a regulating profiling ( 21 ) provided on at least one of an adjacent inner or outer circumferential wall ( 20 , 56 ), said control gap ( 22 ) is variable in terms of its clear throughflow cross section by the throttle body ( 19 ) which deforms under pressure of fluid flowing through.

2. The installation element ( 2 , 3 , 4 , 5 , 6 , 7 ) as claimed in claim 1 , wherein at least one of the inner or the outer circumferential wall ( 20 , 56 ), at least in partial region which has the regulating profiling ( 21 ), or the regulating profiling ( 21 ), widen in terms of a clear cross section in the longitudinal direction.

3. The installation element ( 2 , 3 , 4 , 5 , 6 , 7 ) as claimed in claim 2 , wherein a support ( 23 ) for the throttle body ( 19 ), or at least one of the inner or outer circumferential wall ( 20 , 56 ) which has the regulating profiling ( 21 ), is designed as the adjustment element ( 10 ) which interacts with at least one of the inner or outer circumferential wall ( 20 , 56 ) which is designed as the regulating element ( 9 ) or with the support ( 23 ).

4. The installation element ( 2 , 3 , 4 , 5 , 6 , 7 ) as claimed in claim 3 , wherein the adjustment device can be releasably fastened on the inflow side of a jet regulator ( 11 ) or similar sanitary installation part.

5. The installation element ( 2 , 3 ) as claimed in claim 3 , wherein the adjustment device has a sleeve-shaped housing ( 26 ), in a housing interior of which the support ( 23 ) which serves as a regulating element ( 9 ) is arranged so as to be immovable in the longitudinal direction.

6. The installation element ( 2 , 3 ) as claimed in claim 3 , wherein the adjustment element ( 10 ) is formed as the inner circumferential wall ( 20 ), which bears a regulating profiling ( 21 ), of a profile ring.

7. The installation element ( 2 , 3 ) as claimed in claim 6 , wherein the support ( 23 ) which bears the throttle body ( 19 ) protrudes into the ring opening of the profile ring.

8. The installation element ( 2 , 4 , 7 ) as claimed in claim 7 , wherein the housing ( 26 ) of the adjustment device bears an internal thread on a housing inner circumference thereof, and on the outer circumferential wall of the adjustment element ( 10 ), at least one external thread, a sliding peg or projection protrudes into the internal thread.

9. The installation element ( 2 ) as claimed in claim 8 , wherein the support ( 23 ) is held on the operating element ( 8 ).

10. The installation element ( 3 ) as claimed in claim 9 , wherein the sleeve-shaped housing of the adjustment device which bears at least one ramp ( 30 ) on a housing inner circumference, the adjustment element ( 10 ) is formed as the inner circumferential wall, which bears a regulating profiling ( 21 ), of an annular adjustment element ( 10 ) which rests on the at least one ramp ( 30 ), and a rotational movement at the at least one operating element ( 8 ) can be converted by the at least one ramp ( 30 ) into a longitudinal movement of the adjustment element resting on the at least one ramp ( 30 ).

11. The installation element ( 2 , 3 , 7 ) as claimed in claim 10 , wherein at least one driver or drive peg protrudes from the operating element ( 8 ), said driver or drive peg engages into an associated driver or coupling opening on the adjustment element.

12. The installation element ( 4 ) as claimed in claim 11 , wherein the filter or upstream screen ( 14 ) formed as the operating element ( 8 ) is of pot-shaped form, the filter or upstream screen ( 14 ) is mounted with a pot edge region thereof in a rotatable manner on the inflow side of the installation part ( 11 ), the filter or upstream screen ( 14 ) has, on a pot inner circumference of the pot shape, a thread or a helical groove ( 35 ) into which protrudes a counterpart threat or at least one sliding piece or similar projection on an outer circumference of the support ( 23 ) formed as the adjustment element ( 10 ), which support a profile ring is provided which is held in a rotationally fixed manner on the installation element ( 4 ) and the inner circumferential wall ( 20 ) of which, formed as the regulating element, bears the regulating profiling ( 21 ), and the support ( 23 ) is wheel-shaped and is guided with spokes of the wheel shape in guide grooves or openings of the profile ring in a rotationally fixed manner but so as to be displaceable in the longitudinal direction.

13. The installation element ( 5 ) as claimed in claim 3 , wherein a threaded peg or a threaded sleeve protrudes from the support ( 23 ) designed as the adjustment element ( 10 ), said threaded peg or sleeve is guided in a rotationally fixed but displaceable manner in the installation element ( 5 ) and interacts with a counterpart thread of a threaded sleeve or of a threaded peg whose outflow-side sleeve or peg end region, which protrudes beyond the installation element ( 5 ), is designed as the operating element, and the regulating profiling is provided on the inner circumferential wall ( 20 ), designed as the regulating element ( 9 ), of the installation element ( 5 ).

14. The installation element ( 6 ) as claimed in claim 3 , wherein the support ( 23 ) is designed as the adjustment element ( 10 ) and is guided on the housing inner circumference of the housing ( 26 ) of the adjustment device so as to be displaceable in the longitudinal direction of the adjustment device.

15. A sanitary installation element ( 1 , 2 , 3 , 4 , 5 , 6 , 7 ) which can be inserted into a water outlet of a sanitary outlet fitting, comprising a housing having a throughflow cross-section, a perforated plate extending across the throughflow cross-section of the housing, the perforated plate including a plurality of throughflow holes defined therein through which a flow of water is directed, an adjustment device for varying at least one of the clear throughflow cross-section of the installation element or a volume flow, said adjustment device is actuatable by at least one operating element ( 8 ) arranged for actuation on at least one of an inflow side of the installation element or on an outflow side of said installation element, wherein the adjustment device has a regulating element ( 9 ) and, interacting therewith, an adjustment element ( 10 ), a relative position
