PISTON MOTOR WITH IMPROVED STARTING CHARACTERISTICS

摘要

hydraulic piston motor having a rotary actuator (28) in abutment against a fixed orifice plate (46), and a head with a start-up load device (78) used to provide a hydrostatic pressure confined between the orifice plate (46) and cy rotary lindre (28), so as to reduce the friction to start and improve the starting torque.
