Abstract

A sanitary insert part includes an insert housing, which includes in a housing interior thereof a functional element that controls throughflow and that has at least one throughflow orifice. At least one throughflow opening is delimited by a peripheral wall, the shape of which can be changed against a restoring force as a result of the pressure of the inflowing water in such a manner that the at least one throughflow orifice has a variable orifice cross section which can be changed, in dependence on the pressure of the inflowing water, between an open position and a minimized position having a reduced orifice cross section by comparison.

First claim

The invention claimed is:

1. A sanitary insert part ( 1 , 100 , 101 ) comprising an insert housing ( 2 ), the insert housing ( 2 ) has in a housing interior thereof a functional element ( 3 ) that controls throughflow and that has a plurality of throughflow orifices ( 4 ), the throughflow orifices ( 4 ) delimited by a peripheral wall, a shape of which is changeable against a restoring force as a result of pressure of inflowing water such that the throughflow orifices ( 4 ) each have a variable orifice cross section which is changable, in accordance with the pressure of the inflowing water, between an open position and a minimum position having a reduced orifice cross section by comparison, wherein the functional element ( 3 ) is formed at least in two parts and comprises at least one functional part ( 5 ), comprising the at least one peripheral wall delimiting the throughflow orifices ( 4 ), and a support part ( 6 ) bearing the at least one functional part ( 5 ), the support part ( 6 ) comprising a plurality of insert orifices ( 8 ) each one individually coaxial with one of the throughflow orifices ( 4 ) and wherein the sanitary insert part ( 1 , 100 , 101 ) is formed as a jet regulator for a consolidated complete jet at the water outlet of a sanitary outlet fitting.

2. The insert part as claimed in claim 1 , wherein the support part ( 6 ) is produced from a material that is at least one of dimensionally stable compared with the functional part ( 5 ) on an inflow side or has an at least partly higher component part stiffness by comparison.

3. The insert part as claimed in claim 1 , wherein a water pressure acting on an inflow side of the functional element ( 3 ) at least in a region of the at least one throughflow orifice ( 4 ) in a throughflow direction causes a height reduction of the functional element ( 3 ) that is convertible into a radial constriction movement of the at least one peripheral wall delimiting the at least one throughflow orifice ( 4 ).

4. The insert part as claimed in claim 1 , wherein a water pressure acting on an inflow side of the functional element ( 3 ) at least in a region of the at least one throughflow orifice ( 4 ) in the throughflow direction causes a change in shape of the functional part ( 5 ) or a material displacement at the functional part ( 5 ) that is convertible into a radial constriction movement of the at least one peripheral wall delimiting the at least one throughflow orifice ( 4 ).

5. The insert part as claimed in claim 4 , wherein the change in shape or material displacement caused by the water pressure is an at least partial thickness reduction, cross section reduction, height reduction or compression of the functional part.

6. The insert part as claimed in claim 1 , wherein the at least one peripheral wall delimiting one of the throughflow orifices ( 4 ) has a shaping that converts an application of pressure, caused by the water pressure, in an axial direction into a radial constriction movement of said peripheral wall.

7. The insert part as claimed in claim 6 , wherein to convert an application of pressure in the axial direction into a radial constriction movement, the at least one peripheral wall delimiting the throughflow orifice ( 4 ) either has, on an outer periphery at a free end region thereof as oriented in the throughflow direction, a run-on bevel that cooperates with a mating bevel ( 9 ) on the support part ( 6 ), or has a constriction ( 10 ) with a peripheral bending zone ( 31 ) protruding into the throughflow orifice ( 4 ).

8. The insert part as claimed in claim 1 , wherein the at least one peripheral wall delimiting the at least one throughflow orifice ( 4 ) is formed as a nozzle-shaped formation ( 7 ) of the functional part ( 5 ).

9. The insert part as claimed in claim 8 , wherein the at least one nozzle-shaped formation ( 7 ) of the functional part ( 5 ) dips into an insert orifice ( 8 ) in the support part ( 6 ).

10. The insert part as claimed in claim 9 , wherein the at least one insert orifice ( 8 ) tapers in the throughflow direction such that an axial feed movement of the nozzle-shaped formation ( 7 ) is convertible into a radial constriction movement in the region of the formation ( 7 ).

11. The insert part as claimed in claim 8 , wherein the at least one nozzle-shaped nozzle ( 7 ) has a shaping that is flexible in the axial direction such that an axial compression of the nozzle shaped formation ( 7 ) is convertible into a radial constriction movement in a region of the formation ( 7 ).

12. The insert part as claimed in claim 10 , wherein a relative movement, convertible into the radial constriction movement of the at least one peripheral wall delimiting the at least one throughflow orifice ( 4 ), between the functional part ( 5 ) and the support part ( 6 ) of the functional element ( 3 ) is delimited by at least one stop.

13. The insert part as claimed in claim 9 , wherein an inflow-side end edge ( 12 ) of the insert orifice ( 8 ) in the support part ( 6 ) delimits a pressure-induced axial relative movement of the functional part ( 5 ).

14. The insert part as claimed in claim 9 , wherein the functional part ( 5 ) has a plurality of the nozzle-shaped formations ( 7 ) on the outflow side and the outflow side of the functional part ( 5 ) and an adjacent flat side of the support part ( 6 ) are matched to one another in terms of their shape.

15. The insert part as claimed in claim 1 , wherein the functional element ( 3 ) of the insert part ( 1 , 100 , 101 ) formed as the jet regulator is formed as a jet splitter that controls a throughflow rate.

16. The insert part as claimed in claim 15 , wherein the sanitary insert part ( 1 , 100 , 101 ) is formed as an aerated jet regulator, and at least one aeration opening ( 32 ) is provided on an outflow side of the jet splitter on a housing periphery of the insert housing ( 2 ) and connects a housing interior of the insert housing ( 2 ) to the ambient air.

17. The insert part as claimed in claim 1 , wherein a gap ( 22 ) provided between the functional part ( 5 ) and the support part ( 6 ) is connected via at least one ventilation channel to ambient air and the at least one ventilation channel penetrates the support part ( 6 ) and has a channel opening ( 20 ), which is provided on an outflow side of the support part ( 6 ).

18. The insert part as claimed in claim 1 , wherein the functional part ( 5 ) rests, via an outer peripheral edge region ( 33 ) thereof, on an adjacent peripheral edge region ( 34 ) of the support part ( 6 ).

19. The insert part as claimed in claim 9 , wherein the at least one insert orifice ( 8 ), in its conically tapering orifice portion, has slide formations that are distanced from one another in a peripheral direction and are acted on by a free end region of the nozzle-shaped formation ( 7 ) of the functional part ( 5 ).
