御装置。 Poppet valves 3 and 5 are interposed between the hydraulic pump 2 and the actuator 1, between the actuator 1 and the hydraulic pump 2, or between the hydraulic pump 2 and the tank to open and close a flow path; In order to control the opening and closing of the poppet valve 5, the closing side chambers of the poppet valves 3 and 5 communicated with the upstream side via a throttle and the poppet valve 3.
.
When overstroke is achieved by 0, the space 12 between the valve body 7 of the pilot valve 6 and the solenoid 10 is opened by the stroke of the pilot spool 8 to a notch 14 that communicates with the port communicating with the closed side chamber of the poppet valve. A hydraulic control device characterized in that:
