Abstract

A sanitary outlet armature having a water outlet with an outlet opening bounded by an inner circumferential wall of the outlet armature, at which inner circumferential wall an internal thread or similar receptacle is provided, in which a sleeve-shaped outlet orifice having an external thread or similar mating receptacle can be threaded in or attached, an insert cartridge being inserted and/or threaded into the outlet orifice, said cartridge including a jet regulator. The outlet orifice supports at least one sealing ring on the circumferential wall thereof, this ring radially or axially sealing between the outer circumferential wall of the outlet orifice and the inner circumferential wall of the outlet armature. The outlet armature allows a reduced production effort and easier maintenance, without sacrificing functionality and seal tightness in the area of the outlet opening.

First claim

What is claimed is:

1. A sanitary outlet armature ( 7 ) comprising a water outlet, which has an outlet opening ( 6 ) defined by an inner circumferential wall ( 4 ) of the outlet armature ( 7 ), an inner thread ( 3 ) being provided on said inner circumferential wall ( 4 ), a sleeve-shaped outlet orifice ( 5 , 8 , 11 , 14 , 17 ), which can be screwed or fastened into a receptacle by an outer thread ( 2 ), and an insert cartridge ( 9 ), which can be at least one of inserted or screwed into the outlet orifice ( 5 , 8 , 11 , 14 , 17 ), said insert cartridge ( 9 ) having a jet regulator, wherein the outlet orifice ( 5 , 8 , 11 , 14 , 17 ) carries on a circumferential wall thereof at least one ring seal ( 18 ), which, in a functional position, at least one of radially or axially seals between an outer circumferential wall ( 1 ) of the outlet orifice ( 5 , 8 , 11 , 14 , 17 ) and the inner circumferential wall ( 4 ) of the outlet armature ( 7 ), the outlet orifice ( 5 , 8 , 11 , 14 , 17 ), in the functional position, protrudes beyond the outlet armature via a partial region on an outflow side, at least one tool engagement surface ( 32 ) for a rotary tool is provided on the partial region of the outlet orifice ( 5 , 8 , 11 , 14 , 17 ) protruding beyond the outlet armature ( 7 ) in the functional position, and the tool engagement surface is formed as a two-sided spanner engagement surface, wherein the outlet armature ( 7 ) has an armature body ( 12 ), which carries the outlet opening ( 6 ) in an outer circumference thereof, and the outlet opening ( 6 ) has at least one of a constant or shoulder-free clear opening cross section, discharging into an inner cavity ( 13 ) of the outlet armature ( 7 ).

2. The outlet armature as claimed in claim 1 , wherein a circumferential groove ( 19 ) is provided in an outer circumference of the outlet orifice ( 5 , 8 , 11 , 14 ,) and the ring seal ( 18 ), is held in said groove.

3. The outlet armature as claimed in claim 1 , wherein the insert cartridge ( 9 ) is held in the outlet orifice ( 5 , 8 , 11 , 14 , 17 ), so as to be secured on either side in an axial direction.

4. The outlet armature as claimed in claim 1 , wherein the insert cartridge ( 9 ) is insertable into the outlet orifice ( 5 ) from an inflow side thereof as far as an insertion stop ( 20 ).

5. The outlet armature as claimed in claim 4 , wherein the insert cartridge ( 9 ) is held in the outlet orifice ( 5 ) so as to be axially secured between the insertion stop ( 20 ) and a retainer ( 21 ) that is releasably fastened to an inner circumference of the outlet orifice ( 5 ).

6. The outlet armature as claimed in claim 4 , wherein a ring seal ( 25 ) is provided between the insert cartridge ( 9 ) and the retainer ( 20 ) and seals a region between the insert cartridge ( 9 ) and the inner circumference of the outlet orifice ( 5 ).

7. The outlet armature as claimed in claim 1 , wherein the insert cartridge ( 9 ) can be inserted into the outlet orifice ( 8 , 11 , 14 , 17 ) from the outflow side thereof as far as an insertion stop.

8. The outlet armature as claimed in claim 7 , wherein the insertion stop ( 16 ) is formed as an annular shoulder or annular flange arranged on the inner circumference of the outlet orifice.

9. The outlet armature as claimed in claim 8 , wherein the insertion stop ( 16 ) designed as an annular flange is arranged in a transverse plane to the outlet orifice ( 8 , 11 , 17 ) on the inflow side.

10. The outlet armature as claimed in claim 1 , wherein the outlet orifice ( 8 , 11 , 14 , 17 ) carries on an inner circumference thereof an inner thread ( 28 ), into which an outer thread ( 29 ) provided on an outer circumference of the cartridge housing or of an intermediate retainer can be screwed.

11. The outlet armature as claimed in claim 7 , wherein a ring seal ( 40 ) is provided between the insert cartridge ( 9 ) and the insertion stop ( 16 ) and axially seals a region between the insert cartridge ( 9 ) and an inner circumference of the outlet orifice ( 8 , 17 ).

12. The outlet armature as claimed in claim 1 , wherein at least one ring seal ( 30 ) is provided on the cartridge housing of the insert cartridge ( 9 ) and radially seals a region between the insert cartridge ( 9 ) and an inner circumference of the outlet orifice ( 11 , 14 ).
