Abstract

PURPOSE: To miniaturize and lighten the whole body of the regulator by a method wherein an oil cooler is arranged on the actuator oil returning pipe lane of a control valve of hydraulic actuator to cool only the actuator oil returning to the actuator oil tank and to minimize the capacity of the oil cooler.
CONSTITUTION: A control valve 4 is connected with a rotary oil joint 109 consisting of a part of the oil pressure actuator 103 through the intermediary of the oil pressure piping, and the control valve 4 is controlled by a control signal S from a control unit 5. An actuating oil returning pipe 6 and an actuating oil supply pipe 7 are connected with the control valve 4, and the actuator oil supply pipe 7 is equipped with a pump 8 and a relief valve 9 in turn like this from its upstream side. An oil cooler 10 is arranged on the actuator oil returning pipe 6. Therefore, only the actuator oil returning from the control valve 4 to an actuator oil tank 11 is cooled. Supply of the actuator oil to the oil pressure actuator 103 is easier because of no resistance of the oil cooler 10 on the side of the supply pipe lane 7 to the control valve 4.
