Abstract

A sanitary insert, which is arranged in a water line, is provided. The sanitary insert includes a mixing device with at least one throttling or closing element, which can be moved under the pressure of the inflowing water from a mixing or open position into a throttling or closed position against a restoring force. The mixing device offers a relatively large clear flow cross section when the at least one throttling or closing element in the mixing or open position, and, by contrast thereto, a reduced clear flow cross section when the at least one throttling or closing element is in the throttling or closed position. The installation element always offers an optimum flow cross section both in low and high pressure ranges.

First claim

The invention claimed is:

1. A sanitary installation element ( 106 , 115 , 117 ) which is arranged in a water line that is embodied as a jet regulator, comprising a jet splitter ( 2 ), having a plurality of openings which divide an inflowing water flow into a multiplicity of individual jets, and having an admixing device ( 4 ) with at least one throttling or closing element ( 5 , 5 ″), the at least one throttling or closing element ( 5 , 5 ″) can move, under pressure of the inflowing water, from an admixing or open position into a throttling or closed position counter to a restoring force, with the admixing device ( 4 ), in the admixing or open position of the at least one throttling or closing element ( 5 , 5 ″), providing a clear throughflow cross section, and in the throttling or closed position of the at least one throttling or closing element ( 5 , 5 ″), providing a reduced clear throughflow cross section in relation thereto, and the at least one throttling or closing element ( 5 , 5 ″), in its throttling or closed position, closes off at least one bypass duct ( 12 ) which bypasses the jet splitter ( 2 ) of the jet regulator, a funnel-shaped filter sieve ( 14 , 14 ′) is positioned upstream of the jet regulator in a flow direction, and a funnel opening of the funnel-shaped filter sieve ( 14 , 14 ′), which is at a downstream side of the filter sieve, is embodied as a duct opening ( 13 ) of the at least one bypass duct ( 12 ) of the admixing device ( 4 ), and said duct opening ( 13 ) has a clear opening cross section which is larger in relation to filter openings ( 15 ) of the filter sieve ( 14 , 14 ′).

2. The sanitary installation element ( 115 , 117 ) of claim 1 , wherein the bypass duct ( 12 ) is coplanar with the openings ( 8 ) of the jet splitter.

3. The sanitary installation element ( 115 , 117 ) of claim 1 , wherein the at least one throttling or closing element ( 5 ″), is circular having an open center portion and an L-shaped cross section.

4. The sanitary installation element ( 115 ) of claim 3 , wherein the filter sieve ( 14 ′) has an open center portion that generally corresponds to an outer shape of the at least one throttling or closing element ( 5 ″).

5. The sanitary installation element ( 115 ) of claim 4 , wherein the open center portion of the sieve ( 14 ′) is covered with a covering cap ( 23 ), configured to prevent water from flowing directly onto the at least one throttling or closing element ( 5 ″) and through the open center portion.

6. The sanitary installation element ( 115 ) of claim 1 , wherein the filter sieve ( 14 ′) comprises a portion ( 24 ) configured to secure the closing element ( 5 ″) in place.

7. The sanitary installation element ( 115 , 117 ) of claim 1 , wherein the throttling or closing element ( 5 ″) sealingly covers a center hub portion ( 18 ) of the jet splitter ( 2 ), in such a way that the bypass duct ( 12 ) is closed off.

8. The sanitary installation element ( 106 , 115 , 117 ) of claim 1 , wherein the admixing device ( 4 ) is provided upstream of the jet splitter ( 2 ) at an inflow side.

9. A sanitary installation element ( 116 ) which is arranged in a water line that is embodied as a jet regulator, comprising a jet splitter ( 2 ), which is embodied as a diffuser which divides inflowing water flow into a plurality of individual jets, the jet splitter ( 2 ) comprising wall apertures ( 6 ), which are circumferentially spaced apart from one another in a peripheral wall ( 7 ) with at least one throttling or closing element ( 5 ″), and a flow restrictor ( 19 , 20 , 21 ) coaxially arranged upstream of the jet splitter ( 2 ), the at least one throttling or closing element ( 5 ″) is seated on a center portion of the flow restrictor and can move, under pressure of the inflowing water, from an open position into a throttling or closed position counter to a restoring force, where in a throttling or closed position, the at least one throttling or closing element ( 5 ″) closes off at least one bypass duct ( 12 ′) which is coaxial between a central portion of the jet splitter ( 2 ) and a central portion of the flow restrictor ( 20 ) and bypasses the flow restrictor ( 19 , 20 , 21 ) of the jet regulator.

10. The sanitary installation element of claim 9 , wherein the at least one throttling or closing element ( 5 ″), is circular having an open center portion and an L-shaped cross section.

11. The sanitary installation element of claim 10 , further comprising an ancillary or filter sieve ( 14 ) is positioned upstream of the jet regulator in a flow direction.

12. The sanitary installation element of claim 9 , wherein the flow restrictor ( 19 , 20 , 21 ) is bypassed at low pressure.

13. A sanitary installation element ( 106 , 115 , 117 ) which is arranged in a water line that is embodied as a jet regulator, comprising a jet splitter ( 2 ), having a plurality of openings which divide an inflowing water flow into a multiplicity of individual jets, and having an admixing device ( 4 ) with at least one throttling or closing element ( 5 , 5 ″), the at least one throttling or closing element ( 5 , 5 ″) can move, under pressure of the inflowing water, from an admixing or open position into a throttling or closed position counter to a restoring force, with the admixing device ( 4 ), in the admixing or open position of the at least one throttling or closing element ( 5 , 5 ″), providing a clear throughflow cross section, and in the throttling or closed position of the at least one throttling or closing element ( 5 , 5 ″), providing a reduced clear throughflow cross section in relation thereto, and the at least one throttling or closing element ( 5 , 5 ″), in its throttling or closed position, closes off at least one bypass duct ( 12 ) which bypasses the jet splitter ( 2 ) of the jet regulator, a filter sieve ( 14 , 14 ′) is positioned upstream of the jet regulator in a flow direction, and a funnel opening of the filter sieve ( 14 , 14 ′), which is at a downstream side of the filter sieve, is embodied as a duct opening ( 13 ) of the at least one bypass duct ( 12 ) of the admixing device ( 4 ), and said duct opening ( 13 ) has a clear opening cross section which is larger in relation to filter openings ( 15 ) of the filter sieve ( 14 , 14 ′).

14. The sanitary installation element ( 115 , 117 ) of claim 13 , wherein the bypass duct ( 12 ) is coplanar with the openings ( 8 ) of the jet splitter.

15. The sanitary installation element ( 115 , 117 ) of claim 13 , wherein the at least one throttling or closing element ( 5 ″), is circular having an open center portion and an L-shaped cross section.

16. The sanitary installation element ( 115 , 117 ) of claim 13 , wherein the filter sieve ( 14 ′) comprises a portion ( 24 ) configured to secure the closing element ( 5 ″) in place.

17. The sanitary installation element ( 115 , 117 ) of claim 13 , wherein the throttling or closing element ( 5 ″) sealingly covers a center hub portion ( 18 ) of the jet splitter ( 2 ), in such a way that the bypass duct ( 12 ) is closed off.
