Abstract

PURPOSE: To reduce the power consumption and the cost, by providing means for combining the exhaustions from each pump and supplying for the cooling of hydraulic retarder and for the lubrication of transmission, means for releafing the excessive oil and means for circulating to transmission oil pan.
CONSTITUTION: Exhausted oil q1 from steering pump 16 is separated to steering flow Q1 and the remainder by steering demand valve 1. At low rotation of engine where q1<Q1, the operating oil is supplied from operating machine pump 15 to steering side to assure Q1. During steering operation Q1 flows to the steering 29, but when it isn't operating q1+ q2 flows to hoist control valve 2. The exhausted oil from torque converter pump 17 contributes to the circulation of torque converter 14 and the control of torque converter then combined with the oil q1+q2 from valve 2 and flows through hydraulic retarder 3→oil cooler 4→transmission lubrication 34.
