摘要： The present invention is directed to a rotary joint that includes a power slip ring and an electric signal slip ring, both for passing electricity between a stator and a rotor The system includes a plurality of slip rings (21,31) and a plurality of circumferentially extending fluid flow annular passages (12, 13, 14) formed in axially aligned relaation between the stator and the rotor. Water passages are constituted by some of the annual passages (12,13) and one of the annular passages (14), typically the lowest one, is used an air passage for air under pressure or an air-filled drain so that water leakage can be absorbed into the air passage or drain and does not penetrate into the region of the slip rings. The slip ring (21) with collector rings (22) is used for power and slip rings (31) are used for signals. Water passages are constituted by the annular passages, other than one of the annular passages located towards the power slip ring and the electric signal slip ring.
