Jet regulator

Abstract

A jet regulator for fluids includes a housing wall and a deflecting device arranged at least partially within the housing wall. The deflecting device deflects a centrally inflowing fluid oppositely to its inlet direction. The deflecting device and the housing wall define a flow path.

1 . A jet regulator for fluids including
 a housing wall,   a deflecting device arranged at least partially within the housing wall wherein the deflecting device deflects a centrally inflowing fluid oppositely to an inlet flow direction of the fluid, and   wherein the deflecting device and the housing wall define a flow path.   
     
     
         2 . A jet regulator as claimed in  claim 1 , wherein the distance between the deflecting device and the housing wall in the peripheral direction is substantially constant. 
     
     
         3 . A jet regulator as claimed in  claim 1 , wherein the deflecting device has a preferably central impingement surface, which limits the inflow of the fluid. 
     
     
         4 . A jet regulator as claimed in  claim 1 , wherein the deflecting device has a preferably circular inner wall, which laterally defines the flow path of the fluid. 
     
     
         5 . A jet regulator as claimed in  claim 4 , wherein the inner wall is of continuous construction. 
     
     
         6 . A jet regulator as claimed in  claim 1 , wherein the deflecting device has a convexly domed outer wall. 
     
     
         7 . A jet regulator as claimed in  claim 1 , wherein the deflecting device has an upper overflow edge, which is flat. 
     
     
         8 . A jet regulator as claimed in  claim 1 , wherein the flow path between the deflecting device and the housing wall initially narrows in the flow direction of the fluid and then widens again. 
     
     
         9 . A jet regulator as claimed in  claim 1 , wherein the deflecting device has a rearward, central peg. 
     
     
         10 . A jet regulator as claimed in  claim 9 , wherein the peg tapers towards its free end. 
     
     
         11 . A jet regulator as claimed in  claim 9 , wherein the peg defines with the housing wall, at least in sections, a first annular space. 
     
     
         12 . A jet regulator as claimed in  claim 9 , wherein the peg extends beyond the housing wall, when viewed laterally. 
     
     
         13 . A jet regulator as claimed in  claim 9 , further comprising a flow straightener, which is preferably constructed in the form of a screen and is fixed in position between the housing wall and the peg. 
     
     
         14 . A jet regulator as claimed in  claim 1 , further comprising an inlet device for the fluid, through which the fluid is conducted centrally onto the deflecting device. 
     
     
         15 . A jet regulator as claimed in  claim 14 , wherein the inlet device defines the housing wall. 
     
     
         16 . A jet regulator as claimed in  claim 14 , wherein the inlet device defines with the deflecting device a second annular space. 
     
     
         17 . A jet regulator as claimed in  claim 16 , wherein the fluid flows in the second annular space oppositely to the inlet flow direction of the fluid. 
     
     
         18 . A jet regulator as claimed in  claim 14 , wherein the inlet device is constructed in the form of a flow rate controller or limiter. 
     
     
         19 . A jet regulator as claimed in  claim 1 , wherein the deflecting device includes a fastening device for fastening the deflecting device to an inlet device. 
     
     
         20 . A jet regulator as claimed in  claim 19 , wherein the fastening device is arranged centrally on the deflecting device and permits fastening of the deflecting device from above. 
     
     
         21 . A jet regulator as claimed in  claim 19 , wherein the fastening device is constructed in the form of a preferably circular groove. 
     
     
         22 . A jet regulator as claimed in  claim 19 , wherein the fastening device is constructed in the form of a peg receptacle for receiving a peg on an inlet device. 
     
     
         23 . A jet regulator as claimed in  claim 1 , wherein all the components of the jet regulator comprise a metal. 
     
     
         24 . A method of forming a water jet, wherein
 water is introduced into a jet regulator in a first flow direction;   the water is conducted in the jet regulator initially radially outwardly and then oppositely to the first flow direction; and wherein   the water is then conducted in the jet regulator again radially outwardly and then in the first flow direction.   
     
     
         25 . A method as claimed in  claim 24 , wherein the flow of the water oppositely to the first flow direction occurs at least partially in a second annular space in the jet regulator. 
     
     
         26 . A method as claimed in  claim 24 , wherein the water flows in the radial direction through a vertical annular space before it discharges out of the jet regulator in the first flow direction. 
     
     
         27 . A method as claimed in  claim 24 , wherein the water is initially accelerated in the first flow direction and then decelerated again before it discharges from the jet regulator.
