Abstract
PURPOSE: To improve the responding property of control of operating speed and position of an actuator and reduce the shock at the time of starting, by controlling a change-over valve of a fluid circuit by pilot pressure based on the on-off control of solenoid valves.
CONSTITUTION: The poppet-valve-type solenoid valves 16, 30 conduct the pilot pressure from the upstream sides of valve elements 12, 25 into pilot pressure chambers 13, 26. The unload port 10 of a first valve 2 of a fluid supply system is closed by the valve element 12. The relief port 24 of a second valve 21 of a fluid return system is closed by the valve element 25. The solenoid valves 16, 30 are opened or closed by a controller to operate the valves 2, 21 to control the operating speed and position of the actuator 6. Thereby, the starting shock and travel end shock of the actuator 6 can be reduced.
