Abstract:
1. A jet regulator ( 1 ) comprising a jet fractionating device ( 2 ) for dispersing an incoming water flow into a multitude of individual jets, of which at least one of the individual jets impinges at least one nodal point ( 3 ) of criss-crossing grid bars ( 4 , 5 ), having a downstream surface located in and defining a single plane, of a grid network ( 6 ) arranged downstream from the jet fractionating device that is provided as a separate construction part in a jet regulator housing of the jet regulator, with the at least one nodal point ( 3 ) comprising a recess of the grid network ( 6 ) at an incoming side thereof located above the single plane, and the jet regulator ( 1 ) being an aerated jet regulator ( 1 ) with the jet regulator housing ( 7 ) being provided at a housing perimeter with a plurality of circumferentially separated aeration openings ( 8 ) and at an interior housing circumference in a flow direction below the aeration openings, a deflection projection is located to keep the water jets away from the aeration openings ( 8 ), the deflection projection extending inwardly encircling an inner circumference of an outer wall of the separately constructed grid network ( 6 ).
