Abstract
PURPOSE:To prevent the engine stall by interposing a torque converter between an engine and a gear pump as hydraulic pump for a hydraulic actuator. CONSTITUTION:In a prime motive part, a constant capacity type gear pump P1, gear pump P2, and a gear pump P3 are connected with an engine E through a torque converter 20. As each load of the hydraulic actuators C1-C5 increases, the power of the engine E is transmitted to gear pumps P1-P3 by the action of the torque converter 20, and the low speed revolution having a high torque is automatically realized, and the engine stall is prevented, and the gear pump is put into the high speed revolution state having a low torque, as the load lowers.
