Jet regulator

Abstract

A jet regulator ( 1 ) which can be inserted with its jet regulator housing ( 4 ) into the water outlet ( 2 ) of a sanitary outlet fitting ( 3 ) from a direction of the outlet end side and which, in the use position, is releasably fastened or fixed in the water outlet ( 2 ). The jet regulator is releasably latched in the water outlet ( 2 ). The latching device for fixing the jet regulator in the water outlet ( 2 ) is not visible from the outside and therefore also do not have an objectionable appearance.

1 . A jet regulator ( 1 ) comprising a jet regulator housing ( 4 ) which can be inserted into a water outlet ( 2 ) of a sanitary outlet fitting ( 3 ) from a direction of an outlet end side and which, in a use position, can be releasably fastened or fixed in the water outlet ( 2 ) by a latching part. 
   
   
       2 . The jet regulator of  claim 1 , wherein the latching part comprises at least one spring arm ( 5 ,  6 ) integrally formed on a housing outer periphery of the jet regulator housing ( 4 ), the at least one spring arm ( 5 ,  6 ), in the use position, engages with a free arm end ( 7 ) behind an undercut ( 8 ) on an inner periphery of the water outlet ( 2 ). 
   
   
       3 . The jet regulator of  claim 2 , wherein the free arm end ( 7 ) of the at least one spring arm ( 5 ,  6 ) is spaced apart from the housing outer periphery of the jet regulator housing ( 4 ) in such a way that a release and/or removal tool ( 9 ) can be inserted into a free space between the at least one spring arm ( 5 ,  6 ) and the housing outer periphery. 
   
   
       4 . The jet regulator of  claim 3 , wherein the at least one spring arm ( 5 ,  6 ) is aligned in a flow direction of a water jet emerging from the outlet fitting. 
   
   
       5 . The jet regulator of  claim 3 , wherein the at least one spring arm ( 5 ,  6 ) can, via a pulling movement on the release and/or removal tool ( 9 ) which can be applied to the outer side of the spring arm ( 5 ,  6 ), be acted on with pressure in an outlet direction such that the free arm end ( 7 ) which is arranged opposite at the outflow side can be deflected inward. 
   
   
       6 . The jet regulator of  claim 3 , wherein a tool stop ( 10 ) is provided at an outside on the free arm section of at least one spring arm ( 5 ,  6 ), which tool stop ( 10 ) interacts with the release and/or removal tool ( 9 ) in such a way that a pulling force on the release and/or removal tool ( 9 ) can be transmitted to the spring arm ( 5 ,  6 ) and to the jet regulator housing ( 4 ) which is connected thereto. 
   
   
       7 . The jet regulator of  claim 3 , wherein a run-on bevel ( 11 ) which tapers counter to a pulling direction is provided, for the release and/or removal tool ( 9 ), upstream of the tool stop ( 10 ) at an inflow side on an outside of the at least one spring arm ( 5 ,  6 ). 
   
   
       8 . The jet regulator of  claim 3 , wherein at least one molded-out or molded-in portion ( 13 ) with at least one axially aligned guide wall ( 14 ,  15 ) is provided on the housing outer periphery of the jet regulator housing ( 4 ), which at least one molded-out or molded-in portion ( 13 ) interacts with a counterpart guide surface ( 16 ,  17 ) on the release and/or removal tool ( 9 ). 
   
   
       9 . The jet regulator of  claim 8 , wherein the at least one molded-in portion ( 13 ) with the at least one axially aligned guide wall ( 14 ,  15 ) is provided on the housing outer periphery of the jet regulator housing ( 4 ), and the molded-in portion ( 13 ) interacts with counterpart guide surfaces ( 16 ,  17 ) provided at both sides on the release and/or removal tool ( 9 ). 
   
   
       10 . The jet regulator of  claim 9 , wherein the at least one spring arm ( 5 ,  6 ) is provided in a region of the at least one molded-in portion ( 13 ). 
   
   
       11 . The jet regulator of  claim 2 , wherein there are at least two of the spring arms ( 5 ,  6 ) that are connected to one another by a common tool stop ( 10 ). 
   
   
       12 . The jet regulator of  claim 2 , wherein the at least one spring arm ( 5 ,  6 ) has an L-shape, and a run-on bevel ( 11 ) is provided in a region of a transverse web of the L shape. 
   
   
       13 . The jet regulator of  claim 12 , wherein the L-shaped spring arms ( 5 ,  6 ) are assigned to one another in pairs and are of mirror-symmetrical design with respect to one another. 
   
   
       14 . The jet regulator of  claim 1 , wherein the jet regulator ( 1 ) has a non-circular profile. 
   
   
       15 . The jet regulator of  claim 4 , wherein the free arm end ( 7 ) is aligned in the flow direction. 
   
   
       16 . The jet regulator of  claim 1 , wherein the jet regulator ( 1 ) has an elongate profile. 
   
   
       17 . The jet regulator of  claim 1 , wherein the jet regulator ( 1 ) has a rectangular profile.
