Abstract

A sanitary insert part ( 1 ), including a main body ( 2 ) which provides a radially oriented outer surface ( 3 ), and an elastic regulating body ( 4 ), wherein the base body ( 2 ) forms a regulating core ( 5 ) having a regulating profile ( 6 ) and a regulating gap ( 7 ) is formed between the regulating body ( 4 ) and the regulating profile ( 6 ), such that an opening cross section ( 8 ) of the regulating gap ( 7 ) can be varied by a pressure-dependent loading of the regulating body ( 4 ), characterized in that the main body ( 2 ) forms a radially outwardly open receptacle ( 9 ), the regulating body ( 4 ) is arranged in the receptacle ( 9 ), and an external diameter ( 10 ) of the regulating body ( 2 ) is matched to an outer diameter ( 11 ) of the outer surface ( 3 ).

First claim

The invention claimed is:

1. A sanitary insert part ( 1 ), comprising:
a main body ( 2 ) which provides a radially oriented outer surface ( 3 ), and forming a regulator core ( 5 ) with a regulating profile ( 6 );
an elastic regulating body ( 4 );
a sealing element ( 15 ), which is elastically deformable radially inward, adjacent to the outer surface ( 3 );
a regulating gap ( 7 ) formed between the regulating body ( 4 ) and the regulating profile ( 6 ) such that an opening cross section ( 8 ) of the regulating gap ( 7 ) is variable by a pressure-dependent loading of the regulating body ( 4 );
the main body ( 2 ) forms a radially outwardly open receptacle ( 9 ), the regulating body ( 4 ) is arranged in the receptacle ( 9 ), and an outer diameter ( 10 ) of the regulating body ( 2 ) is matched to an outer diameter ( 11 ) of the outer surface ( 3 ).

2. The sanitary insert part ( 1 ) as claimed in claim 1 , wherein the outer diameter ( 10 ) of the regulating body ( 4 ) is smaller than the outer diameter ( 11 ) of the outer surface ( 3 ).

3. The sanitary insert part ( 1 ) as claimed in claim 1 , wherein the receptacle ( 9 ) is radially outwardly open in an axial portion ( 12 ) taken up by the regulating body ( 4 ).

4. The sanitary insert part ( 1 ) as claimed in claim 1 , wherein the outer surface ( 3 ) is formed on a wall ( 13 ) of the main body ( 2 ), and the outer diameter ( 10 ) of the regulating body ( 4 ) is larger than an inner diameter ( 14 ) of the wall.

5. The sanitary insert part ( 1 ) as claimed in claim 1 , wherein the outer diameter ( 11 ) of the outer surface ( 3 ) defines a maximum radial outer dimension of the main body ( 2 ).

6. The sanitary insert part ( 1 ) as claimed in claim 1 , wherein a cross section of the main body ( 2 ) has a round main shape.

7. The sanitary insert part ( 1 ) as claimed in claim 1 , wherein the regulating body ( 4 ) is annular.

8. The sanitary insert part ( 1 ) as claimed in claim 1 , wherein the main body ( 2 ) is assembled from at least two parts ( 17 , 18 ) that are connected to one another in at least one of a form-fitting, force-fitting, or integrally bonded manner so as not to be releasable without being destroyed.

9. The sanitary insert part ( 1 ) as claimed in claim 8 , further comprising a connecting portion ( 19 ) between the at least two parts ( 17 , 18 ) that extends through the regulating body ( 5 ).

10. The sanitary insert part ( 1 ) as claimed in claim 8 , wherein the at least two parts ( 17 , 18 ) have outer dimensions that describe a common cylinder surface.

11. The sanitary insert part ( 1 ) as claimed in claim 1 , further comprising an at least partially axially acting sealing surface ( 22 ) formed on an outflow side ( 20 ).

12. The sanitary insert part ( 1 ) as claimed in claim 1 , wherein an outer diameter ( 11 ) of the outer surface ( 3 ) is 8 mm or less.

13. A method of controlling a flow, comprising:
inserting the sanitary insert part as claimed in claim 1 , into a tubular portion ( 23 ) that carries a water flow, and
forming a radially outer closure of the receptacle ( 9 ) of the regulating body ( 4 ) using an inner wall ( 24 ) of the tubular portion ( 23 ).

14. The method as claimed in claim 13 , further comprising sealing the outflow side with an at least partially axially acting sealing surface ( 22 ) between the insert part ( 1 ) and the tubular portion ( 23 ) provides a seal on the outflow side with respect to the receptacle ( 9 ), with the sealing surface ( 22 ) lying against a radially inwardly protruding collar ( 25 ) on the tubular portion ( 23 ).

15. The sanitary insert part ( 1 ) as claimed in claim 1 , wherein the outer diameter ( 10 ) of the regulating body ( 4 ) is at most 20% smaller than the outer diameter ( 11 ) of the outer surface ( 3 ).

16. The sanitary insert part ( 1 ) as claimed in claim 1 , wherein the sealing element ( 15 ) comprises an integrally formed sealing lip ( 16 ).

17. The sanitary insert part ( 1 ) as claimed in claim 1 , wherein the main body ( 2 ) is formed integrally, with the receptacle ( 9 ) being at least partially open axially on an end side.
