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).
