Abstract

A sanitary unit ( 1 ) is provided, which is configured for insertion into a discharge fitting. The sanitary unit ( 1 ) includes an upstream sieve ( 2 ) and a throughflow regulator ( 3 ), which includes a control gap ( 10 ) and a throttle body ( 8 ) that deforms under pressure to regulate throughflow varying the control gap ( 10 ). The sanitary unit ( 1 ) also includes a jet fractionating plate ( 4 ), having a plurality of axial openings ( 20 ) in a throughflow direction positioned downstream, in a flow direction, from the throughflow regulator ( 3 ) and the sieve, the throughflow regulator ( 3 ) is arranged within an interior space ( 6 ) between the sieve ( 2 ) and the jet fractionating plate.

First claim

The invention claimed is:

1. A sanitary unit ( 1 ), configured for insertion into a discharge fitting, comprising:
a conical upstream sieve ( 2 ) having an inner surface and an outer surface;
a throughflow regulator ( 3 ), immediately adjacent the sieve ( 2 ), comprising a control gap ( 10 ) and a throttle body ( 8 ) that deforms under pressure to regulate throughflow varying the control gap ( 10 );
a jet fractionating plate ( 4 ), immediately adjacent the throughflow regulator ( 3 ), comprising a plurality of openings ( 20 ) in a throughflow direction positioned downstream, in a flow direction, from the throughflow regulator ( 3 ) and the sieve, wherein the throughflow regulator ( 3 ) is contained within an interior space ( 6 ) of the unit ( 1 ) defined between the sieve ( 2 ) and the jet fractionating plate ( 4 ) and wherein the throughflow regulator ( 3 ) has the same general slope as the inner surface of the sieve ( 2 ).

2. The sanitary unit of claim 1 , wherein the throughflow regulator ( 3 ) is arranged in the interior space ( 6 ) such that it sits on the jet fractionating plate ( 4 ) and is displaceable in an axial throughflow direction.

3. The sanitary unit of claim 2 , wherein axial displacement of the throughflow regulator ( 3 ) within the interior space ( 6 ) is limited by the sieve ( 2 ), which is connected to the jet fractionating plate ( 4 ).

4. The sanitary unit of claim 1 , wherein the throughflow regulator ( 3 ) is kept in place by the sieve ( 2 ), which is connected to the jet fractionating plate ( 4 ) by a press fit.

5. The sanitary unit of claim 1 , wherein a ratio of an overall height of the sanitary unit ( 1 ) to a height of the interior space ( 6 ) is in a range of approximately 3:1 to 4:1.

6. The sanitary unit of claim 1 , wherein the sanitary unit ( 1 ) has an overall height that is 3 to 4 times greater than a maximum height of the interior space ( 6 ).

7. The sanitary unit of claim 1 , wherein the sanitary unit ( 1 ) has an overall height that is 3 times greater than a maximum height of the interior space ( 6 ).

8. A jet regulator ( 1 ), configured for insertion into a discharge fitting, comprising a conical upstream sieve ( 2 ) having and inner surface and an outer surface; a throughflow regulator ( 3 ) immediately adjacent the sieve ( 2 ), comprising a throttle body ( 8 ) and control gap ( 10 ) defining a passage leading to a jet fractionating plate ( 4 ), comprising a plurality of axial openings ( 20 ) in a downstream direction, positioned downstream in a flow direction from the sieve, wherein the throughflow regulator ( 3 ) is contained within an interior space ( 6 ) of the unit defined by an area delimited by the sieve in an upstream direction and the jet fractionating plate ( 4 ) in a downstream direction, the throughflow regulator ( 3 ) is kept in place by the sieve ( 2 ), which is connected the jet fractionating plate ( 4 ) by a press fit wherein the throughflow regulator ( 3 ) has the same general slope as an inner surface of the sieve ( 2 ).

9. The jet regulator ( 1 ) of claim 8 , wherein the throughflow regulator ( 3 ) is arranged on the jet fractionating plate ( 4 ) and is prevented from axial movement by the sieve ( 2 ).

10. The jet regulator ( 1 ) of claim 8 , wherein a ratio of an overall height of the jet regulator ( 1 ) to a maximum height of the interior space ( 6 ) is in a range of approximately 3:1 to 4:1.

11. The jet regulator ( 1 ) of claim 8 , wherein the jet regulator ( 1 ) has an overall height that is 3 to 4 times greater than a maximum height of the interior space ( 6 ).

12. The jet regulator of claim 8 , wherein the jet regulator ( 1 ) has an overall height that is 3 times greater than a maximum height of the interior space ( 6 ).
