Hydraulic rotary motor for rotation of electrical load mounted on a vehicle, e.g. an excavator, has electrical supply leads for latter fed through stationary head of motor

摘要

The hydraulic rotary motor has working pressure chambers (27) supplied with a hydraulic fluid for providing rotation of an output shaft (26) for rotation of an electrical load, e.g. an electromagnet, supplied via electrical leads (19,20) fed through the stationary head (9) of the motor, with a slip-ring device (2,3,4,5,6,7,8) between the stationary head and the output shaft. An independent claim for a mobile vehicle with a hydraulic rotary motor for rotation of an electrical load is also included.
