Abstract
PURPOSE: To minimize the capacity of a filter and decrease loss of pressure by a method wherein a filter is arranged at the inlet of control valve, a relief valve arranged at the upstream side of the filter, and only the dust in an actuating oil to enter the control valve is filtered.
CONSTITUTION: A control valve 4 is connected with the rotary oil joint 109 composing 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 the control unit 5. An actuating oil returning pipe 6 and an actuator oil supply pipe 7 are connected with the control valve 4, and a pump 8, a relief valve 9 and a filter 10 are arranged on the actuator oil supply pipe 7 in turn from its upstream side. Only the dust in the actuator oil to enter the control valve 4 is filtered, the dust in the actuator oil to return to the actuating oil tank 11 is not filtered, and only the dust in the necessary minimum quantity of actuating oil is always filtered so that capacity of the filter 10 may be smaller.
