Patent ID: 8672244

Claim:
A jet former ( 1 ), which can be fitted in the water outlet ( 2 ) of a sanitary outlet fitting, the jet former comprising at least one homogenizing device ( 3 ) with a multiplicity of throughflow holes ( 4 ) which are delimited in each case by flow-guiding walls ( 5 ), the jet former ( 1 ) in a plane defined transverse to a throughflow direction at an outlet end has a greater jet width ( 1 ) in comparison to a jet depth (t) for producing a flat water jet band, a flow guide ( 6 ), which tapers in a nozzle-like manner in a throughflow direction at least in one section, is connected upstream or downstream of the at least one homogenizing device ( 3 ), and the flow guide ( 6 ) has a greater longitudinal extent in a direction of the jet width in comparison to a depth thereof in the plane defined transverse to the throughflow direction at the outlet end, wherein on both sides of the longitudinal extent, edge regions ( 7 , 8 ) of the flow guide ( 6 ) are provided with a larger throughflow cross section in the plane defined transverse to the throughflow direction in comparison to a throughflow cross-section of a longitudinal middle region ( 9 ) of the flow guide ( 6 ).
