Abstract
PURPOSE:To prevent plural actuators from being operated by external force by providing a differential valve to stop the operation of the plural actuators caused by an oil flow through the plural actuators when a directional control valve is in a neutral position. CONSTITUTION:When a directional control valve 3 is in a neutral position A0 and external force is applied to an actuator 4, a pressure is generated on a bottom 4B so as to shift a differential change-over valve 101 to a position B2. A differential change-over valve 201 is shifted to a position C1 due to said shift. In this case, since outlet ports 106, 206 of a pipeline 9 to a bottom chamber 5B within one actuator 5, are connected/disconnected respectively to/from inlet ports 102, 202 in positions B1, C1 of differential change-over valves 101, 202, oil on the bottom 4B of the other actuator 4 can not flow into the bottom 5B of said actuator 5.
