Abstract

A sanitary insertion unit includes an insertion housing in which at least one closing valve having an annular channel is provided. An annular valve body composed of elastic material is arranged in the annular channel, the valve body deforms under the pressure of the incident fluid in such a way that the valve body tightly closes the annular channel. The annular channel of the closing valve has a profile on an inner and outer channel wall. Via the profile, better controllability of the closing valve during the closing process of the valve body of the closing valve can be achieved and disturbing noises and vibrations are effectively avoided.

First claim

What is claimed is:

1. A sanitary insert unit ( 1 ) having an insert housing ( 2 ), with a single flow path, in which at least one closing valve ( 3 ) having an annular channel ( 4 ) is provided in said housing ( 2 ), said annular channel ( 4 ) defined by an inner channel wall (I) and an outer channel wall (O), the annular channel ( 4 ) having an annular valve body ( 5 ) made of resilient material is arranged therein, which deforms under pressure of an inflowing fluid such that the valve body ( 5 ) tightly closes the annular channel ( 4 ), wherein the single flow path is maintained upstream of the valve body ( 5 ) and wherein the annular channel ( 4 ) of the at least one closing valve ( 3 ) has profiling ( 6 ) on both the inner channel wall (I) and the outer channel wall (O), the inner and outer walls (I, O) facing each other with the single flow path and arranged annular channel ( 4 ) between them.

2. The sanitary insert unit as claimed in claim 1 , wherein the profiling ( 6 ) is configured in an encircling manner on the inner and outer channel walls (I, O).

3. The sanitary insert unit as claimed in claim 2 , wherein the profiling ( 6 ) is formed from alternate indentations ( 7 ) and protuberances ( 8 ).

4. The sanitary insert unit as claimed in claim 3 , wherein at least one of the indentations ( 7 ) or the protuberances ( 8 ) have a rounded, semicircular, cross-sectional contour.

5. The sanitary insert unit as claimed in claim 3 , wherein each indentation ( 7 ) is configured as a region arranged between two protuberances ( 8 ) that immediately adjoin one another.

6. The sanitary insert unit as claimed in claim 1 , wherein the outer channel wall (O) is connected to the inner channel wall ( 1 ) of the at least one annular channel ( 4 ) via radially oriented connecting webs ( 9 ), and the valve body ( 5 ) of the at least one closing valve ( 3 ) bears on the connecting webs ( 9 ) arranged on an outflow side of the at least one annular channel ( 4 ).

7. The sanitary insert unit as claimed in claim 1 , wherein the insert unit ( 1 ) has at least two closing valves ( 3 ), which are provided concentrically with one another in the insert housing ( 2 ).

8. The sanitary insert unit as claimed in claim 1 , wherein the insert unit ( 1 ), in addition to the at least one closing valve ( 3 ), further comprises at least one of: a flow rate regulator or a jet regulator in the insert housing ( 2 ).

9. The sanitary insert unit as claimed in claim 1 , wherein the at least one closing valve ( 3 ) is connected upstream of a jet regulator and a jet splitter of the jet regulator in a flow direction or is connected alongside the jet regulator.
