hitachi — TRAVEL MOTOR

COMPONENT OPERATION / Travel Device 1. Pressure oil in valve plate (1) flows to port A, en- ters into one side in rotor (2), and pushes plunger (3). 2. This force and inclination of swash plate (5) make shoe (4) slide on swash plate (5) in order to rotate rotor (2) and output shaft (6). 3. As rotor (2) rotates, when plungers (3) reach port B, oil is routed to the hydraulic oil tank. 4. Whether pressure oil is supplied to port A or port B determines the travel direction.
