Abstract

PURPOSE: To freely and easily carry out a control of an actuator, by communicating a back pressure chamber of each check valve constituting a control valve with an auxiliary valve through a reducing valve whose pressure setting can be varied by an operation lever.
CONSTITUTION: A control valve 2 is constituted with a combination of the first, second, third and fourth check valves 41, 42, 43, 44. The back pressure chamber of each of the check valves 41, 42, 43, 44, is communicated with an auxiliary pump 5 via reducing valves 7, 8 whose pressure settings can be varied by an operation lever. By such an arrangement, the pressures of the back pressure chambers of the check valves 41, 42, 43, 44 can be selectively raised in response to the tilting direction and angle of the operation lever 9. Consequently, by suitably selecting the manipulation direction and angle of the operation lever 9, it is possible to control the actuation direction and speed of an actuator 3, resulting in a free and easy control of the actuator.
