Abstract
The turbine wheel (30) in the flow duct (28) of the water fitting (10) is subjected to water flowing in the flow direction (S). The turbine wheel (30) drives the rotor (64) of the generator (16) via the common shaft (32). The rotor (16) is surrounded by the beaker-shaped sealing element (66) which is fed through the gap between the stator (80) and the rotor (64) and is connected in a leak-tight manner to the casing (12). The rotor (64) therefore rotates within the water-filled sealing element (66).
