Jet regulator

Abstract

A jet regulator ( 1 ) having a jet regulator housing ( 4 ) including a housing part ( 5 ) having a sleeve-shaped housing wall ( 7 ), the sleeve interior of the housing part ( 5 ) being integrally connected to a jet fractionater ( 8 ) oriented transverse to the flow direction and including a plurality of flow-through openings ( 9 ) for dividing the inflowing water flow into a plurality of individual streams, a screen ( 11 ) being releasably supported in the sub-region ( 10 ) of the sleeve interior separated by the jet fractionater ( 9 ) on the inflow side. The jet regulator ( 1 ) according to the invention is characterized in that an external thread ( 12 ) is provided on the external circumference of the section ( 7 ) of the housing wall ( 7 ) bounding the inflow side sub-region ( 10 ) of the sleeve interior. This external thread ( 12 ) is provided in a section of the jet regulator housing ( 4 ) that is not particularly exposed to the water pressure and therefore can be designed having relatively thin walls, and in which no further insertion parts that could further constrict the flow-through cross-section are to be received as a rule in the jet regulator housing ( 4 ).

1 . A jet regulator ( 1 ) comprising a jet regulator housing ( 4 ) which has a housing part ( 5 ) with a sleeve-shaped housing wall ( 7 ), said housing part ( 5 ), in a sleeve interior thereof, is integrally connected to a jet fractionater ( 8 ) which is oriented transversely with respect to a direction of flow and has a plurality of flow-through openings ( 9 ) for dividing an incoming water flow into a plurality of individual jets, an external thread ( 12 ) is provided on an outside circumference of a portion ( 7 ′) of the housing wall ( 7 ) defining an upstream part region ( 10 ) of the sleeve interior. 
     
     
         2 . The jet regulator as claimed in  claim 1 , wherein at least one of an attachment screen ( 11 ) or a flow regulator ( 30 ) is held in the upstream part region ( 10 ) of the sleeve interior which is divided up by the jet fractionater ( 8 ). 
     
     
         3 . The jet regulator as claimed in  claim 2 , wherein the upstream part region ( 10 ) of the sleeve interior is dimensioned for complete accommodation of the at least one of the attachment screen ( 11 ) or the flow regulator ( 30 ) in such a manner that an upstream end circumferential edge ( 13 ) of the jet regulator housing ( 4 ) forms an upstream closure of a unit formed of the jet regulator ( 1 ) and the at least one of the attachment screen ( 11 ) or the flow regulator ( 30 ). 
     
     
         4 . The jet regulator as claimed in  claim 1 , wherein the jet regulator ( 1 ) has at least one of an axial or at least one radial annular seal ( 17 ;  18 ,  19 ) for sealing a space provided between the jet regulator outer circumference and an inner circumference of a sanitary outlet fitting. 
     
     
         5 . The jet regulator as claimed in  claim 1 , wherein at least one groove ( 16 ) for accommodation of a sealing ring ( 17 ) is provided on an outer circumference of the jet regulator housing ( 4 ). 
     
     
         6 . The jet regulator as claimed in  claim 1 , wherein a sealing ring ( 18 ;  19 ), which seals between the jet regulator ( 1 ) and an annular shoulder ( 20 ) provided on an inner circumference of a sanitary outlet fitting ( 3 ), is provided for axial sealing. 
     
     
         7 . The jet regulator as claimed in  claim 1 , wherein an axially effective sealing ring ( 18 ) rests on an upstream end circumferential edge ( 13 ) of the jet regulator housing ( 4 ). 
     
     
         8 . The jet regulator as claimed in  claim 1 , wherein an axially effective sealing ring ( 18 ) is supported in the upstream sleeve interior and projects over an upstream end circumferential edge ( 13 ) of the jet regulator housing ( 4 ). 
     
     
         9 . The jet regulator as claimed in  claim 1 , wherein at least one tool contact surface for a rotary tool ( 21 ) is provided on at least one of a downstream end edge, the outer circumference of the jet regulator housing ( 4 ) or a downstream end face of the jet regulator housing ( 4 ). 
     
     
         10 . The jet regulator as claimed in  claim 1 , wherein housing moldings ( 22 ,  22 ′), which serve as tool contact surfaces for a rotary tool ( 21 ), are provided on the outer circumference of the jet regulator housing ( 4 ).
