Water fitting for sanitary installations
First Claim
1. Water fitting, particularly for domestic sanitary installations, having a flow duct, having a turbine wheel arranged in this flow duct and acted on by flowing water and having an electrical generator driven by the turbine wheel and sealed against the flow duct, wherein a wall part (58) in a non-magnetizable material and separating the flow duct (22) from the generator (20) is provided, wherein a first coupling part (28) connected to the turbine wheel (240 is arranged on one side of the wall part (48) and a second coupling part (30) connected to the generator is arranged on the other side, the coupling parts (28, 30) being magnetically coupled with one another, wherein the turbine wheel is supported on a shaft, one end of which is rotatably supported on the partition element, which is fixed to the cylindrical casing part after the introduction of the first coupling part, turbine wheel and shaft into the casing part.

Abstract
The water fitting (10) has a substantially tubular casing (12) which is closed at one end by the partition element (16). The turbine wheel (24) which is acted upon in the axial direction by the water supplied through the inlet connection (14), is rotatably supported within the casing (12). The first coupling part (28), which has an annular permanent magnet (62), is rotationally solidly connected to the turbine wheel (24). The second coupling part (30), which is seated on the rotor shaft (70) of the direct current generator (20), is provided on the other side of the partition element (16). The second coupling part (30) also has an annular permanent magnet (62). The rotational motion of the turbine wheel (24) is transmitted magnetically to the rotor (74) of the direct current generator (20) by means of the two coupling parts (28, 30), this direct current generator supplying the electricity for charging the storage element (32) of the electrical control arrangement (36). The valve (38) is opened and closed by means of the control arrangement (36).
