Abstract

The invention relates to a jet regulator ( 1 ) with a sleeve-shaped jet regulator housing ( 2 ), which ( 2 ) can be mounted on the water outlet of a plumbing outlet armature, and with a sealing ring ( 5 ) made of elastic material, which ( 5 ) seals in an axial direction against an adjoining annular flange at the water outlet of the outlet fixture. On the front inner peripheral area ( 6 ) of the jet regulator housing ( 2 ) on the inflow side, there is provided at least one housing undercut ( 7 ), which secures, on the jet regulator housing ( 2 ), the sealing ring ( 5 ), inserted into the housing interior ( 8 ) of the jet controller housing ( 2 ). In the jet controller ( 1 ) according to the invention, the sealing ring ( 5 ) is effectively secured against unintended loss, for example, during transport or storage.

First claim

The invention claimed is:

1. A jet regulator ( 1 ) comprising a sleeve-shaped jet-regulator housing ( 2 ), with external threads for attachment of the jet regulator ( 1 ) to a water outlet of a sanitary outlet fitting, and having a sealing ring ( 5 ) comprised of an elastic material, which has a rectangular cross section with approximately parallel longitudinal walls and which seals in an axial direction against an adjacent annular surface on the water outlet of the outlet fitting, at least one housing undercut ( 7 ) is provided on an inner circumference on an inlet-side end-edge region ( 6 ) of the jet-regulator housing ( 2 ), by which the sealing ring ( 5 ), which is inserted into a housing interior ( 8 ) of the jet-regulator housing ( 2 ), is secured on the jet-regulator housing ( 2 ), and the housing undercut ( 7 ) is formed into the elastic material of the sealing ring ( 5 ) in such a manner that the sealing ring ( 5 ) is retained in the housing interior ( 8 ) immovable in the axial direction.

2. The jet regulator as claimed in claim 1 , wherein the sealing ring ( 5 ), which is inserted into the jet regulator housing ( 2 ), protrudes beyond an inflow side of the jet-regulator housing ( 2 ).

3. The jet regulator as claimed in claim 1 , wherein proceeding from an inflow side of the jet regulator housing ( 2 ), at least one insert part ( 9 ) is insertable into the housing interior ( 8 ) as far as an insertion stop ( 11 ), and the at least one insert part ( 9 ) is secured in the housing interior ( 8 ) by the sealing ring ( 5 ).

4. The jet regulator as claimed in claim 3 , wherein the at least one insert part ( 9 ) is retained in the housing interior ( 8 ) between the insertion stop ( 11 ) and the sealing ring ( 5 ).

5. The jet regulator as claimed in claim 3 , wherein the at least one insert part ( 9 ) has a perforated structure, grate structure, or mesh structure.

6. The jet regulator as claimed in claim 1 , wherein the jet-regulator housing ( 2 ) includes, on a housing outer circumference thereof, an external thread ( 3 ) for screwing into an internal thread provided in the water outlet of the outlet fitting.
