Abstract

A sanitary outlet insert ( 1 ) which can be mounted on the water outlet of a sanitary outlet fitting, comprising a flow rate regulator ( 2 ) or a flow limiter that has an adjusting element ( 3 ) which regulates or limits the flow area in cooperation with a counter element ( 3 ′). The aim of the invention is to easily adapt said outlet insert to the prevailing on-site water pressure and/or to the corresponding application in a simple manner. According to the invention, this is achieved in that the flow area of the flow rate regulator ( 2 ) or the flow limiter can be preselected or varied by an axial change of the relative position of the adjusting element ( 3 ) and the counter element ( 3 ′); in that additionally a handle is provided on the outlet end face ( 7 ) of the outlet insert ( 1 ), said handle being designed as a pushbutton; and in that an adjusting movement on the handle can be converted into a relative axial movement of the adjusting element ( 3 ) and the counter element ( 3 ′) by means of a pushbutton mechanism.

First claim

2. The outlet insert as claimed in claim 1 , wherein the pushbutton mechanism has a thruster sleeve ( 10 ), by which the relative position of the adjusting element ( 3 , 4 , 6 , 38 ) and the counterelement ( 3 ′, 4 ′, 6 ′, 38 ′) can be changed and the thruster sleeve ( 10 ) has at least one sliding tooth ( 12 ) with an oblique surface ( 13 ), said oblique surface ( 13 ) interacts with a circumferential stepped set of teeth ( 16 ), such that a pressing movement applied to the pushbutton ( 9 ) counter to a restoring force is converted into an axial sliding/turning movement of the sliding tooth ( 12 ), which, during this process, slides into a next step of the stepped set of teeth ( 16 ).

3. The outlet insert as claimed in claim 2 , wherein the stepped set of teeth ( 16 ) is of two- or multi-step design.

4. The outlet insert as claimed in claim 3 , wherein in one step of the two- or multi-step stepped set of teeth ( 16 ), the adjusting element ( 3 , 4 , 6 , 38 ) is arranged outside an operative position provided in a region of the counterelement ( 3 ′, 4 ′, 6 ′, 38 ′).

5. The outlet insert as claimed in claim 2 , wherein the thruster sleeve ( 10 ) is guided in a guide sleeve ( 17 ), which bears the circumferential stepped set of teeth ( 16 ) at one end edge of the sleeve or on an inner circumference of the sleeve.

6. The outlet insert as claimed in claim 5 , wherein an outflow-side end wall ( 19 ) of the insert unit ( 1 , 5 , 8 , 11 , 14 , 50 ) has a grille, net or hole structure and the guide sleeve ( 17 ) is formed integrally or secured on the end wall ( 19 ) or on a front end jet divider.

7. The outlet insert as claimed in claim 2 , wherein the restoring force is generated by a restoring spring ( 44 ).

8. The outlet insert as claimed in claim 5 , wherein the pushbutton ( 9 ) is guided movably in the guide sleeve ( 17 ).

9. The outlet insert as claimed in claim 1 , wherein a jet regulator ( 22 ) is arranged downstream of the flow rate regulator ( 2 ) or the flow limiter ( 2 ′).

10. The outlet insert as claimed in claim 9 , wherein the flow rate regulator ( 2 ) is arranged in the insert unit ( 1 , 5 , 11 , 14 ) between the outflow-side jet regulator ( 22 ) and an inflow-side screen attachment ( 21 ).

11. The outlet insert as claimed in claim 10 , wherein the restoring spring ( 44 ) is supported on at least one of the thruster sleeve ( 10 ) or in the screen attachment ( 21 ).

12. The outlet insert as claimed in claim 9 , wherein the jet regulator has a jet divider which divides the inflowing water into a multiplicity of individual jets.
