Abstract

A sanitary fixture is provided having an upstream end and a downstream end, the sanitary fixture includes a mounting housing having a thread which is matingly engagable with a thread provided on a water outlet of a sanitary outlet fitting. The mounting housing has a downstream housing end side with flow-through holes. At least one insertion part can be inserted into the mounting housing as far as an insertion stop. The fixture includes an aerated jet regulator which is configured such that a circumferential wall of the mounting housing includes at least one aeration duct at least in a subregion of at least a double-walled configuration. The at least one aeration duct, which is arranged towards the downstream housing end side, opens out in at least one aeration opening leading into a housing interior of the mounting housing.

2. The fixture according to claim 1 , wherein an outermost periphery of the diffuser ( 23 ) is secured to an outer periphery of the diffuser ring ( 26 ).

3. The fixture according to claim 1 , wherein the diffuser ring ( 26 ) is insertable into the mounting housing ( 9 ) as far as the insertion stop ( 31 ), and wherein the diffuser ( 23 ), is insertable into the diffuser ring ( 26 ) as far as an insertion stop ( 32 ) of the diffuser ring ( 26 ).

4. The fixture according to claim 1 , wherein the thread ( 10 ) provided on the mounting housing ( 9 ) is an external thread which is arranged on an outer circumference of the housing ( 9 ) and interacts with an internal thread ( 11 ) which is located on an inner circumference of the water outlet ( 70 ) provided in the form of a mating thread ( 11 ).

5. The fixture according to claim 1 , wherein the downstream housing end side ( 12 ) comprises tool engagement surfaces for a rotation tool which can matingly engage with the tool engagement surfaces.

6. The fixture according to claim 1 , wherein the jet splitter has a multiplicity of flow-through openings ( 22 , 41 ) for dividing the stream of water into the multiplicity of individual jets.

7. The fixture according to claim 1 , further comprising a sieve ( 38 ), connected upstream of the throughflow regulator ( 34 ) in the flow direction.

8. The fixture according to claim 1 , further comprising an annular seal ( 33 ) for axial sealing between the fixture and an annular step located in the water outlet ( 7 ).

9. A sanitary fixture ( 1 , 2 , 4 , 5 , 6 , 7 ), having an upstream end and a downstream end, the sanitary fixture ( 1 , 2 , 4 , 5 , 6 , 7 ) comprising a mounting housing ( 9 ) having a thread ( 10 ) which is matingly engagable with a thread ( 11 ) provided on a water outlet ( 70 ) of a sanitary outlet fitting ( 8 ), wherein the mounting housing ( 9 ) has a downstream housing end side ( 12 ) with flow-through holes ( 13 ), and wherein a jet regulator ( 16 ) is insertable into the mounting housing ( 9 ) as far as an insertion stop, the fixture ( 1 , 2 , 4 , 5 , 6 , 7 ) comprises an aerated jet regulator which is configured such that a circumferential wall of the mounting housing ( 9 ) comprises at least one aeration duct ( 14 ), which is arranged towards the downstream housing end side ( 12 ), adjacent the thread ( 10 ) of the mounting housing ( 9 ), at a double walled portion of the housing ( 9 ), the aeration duct ( 14 ) opens out in at least one aeration opening ( 15 ) leading into a housing interior of the mounting housing ( 9 ) and wherein the fixture further comprises a throughflow regulator ( 34 ) which is connected to and upstream of the jet regulator ( 16 ) and wherein the jet regulator ( 16 ) comprises a diffuser ( 23 ) and a diffuser ring ( 26 ), the throughflow regulator ( 34 ) having an outermost periphery which is secured within an outer periphery of the diffuser ( 23 ).

10. The fixture according to claim 9 , wherein the at least one aeration duct ( 14 ) is defined between an inner circumferential wall ( 18 ) and an outer circumferential wall ( 17 ) of the mounting housing ( 9 ).
