Claims

[Scope of utility model registration request]

second and third switching valves that control the actuator;
In the remote position control device for an actuator, the actuator includes a first switching valve that is located upstream of the pair of switching valves and distributes pressure fluid to one of the switching valves, and the second and third switching valves are in the normal position. , the supply port and the return port are short-circuited when the pump is connected to the pump, and a first switching valve is connected to the upstream side of the second switching valve, and the first switching valve is connected to the pump port directly connected to the pump. , a tank port directly connected to the tank, an outflow port connected to the supply port of the second switching valve, an inflow port connected to the return port of the second switching valve, and a third switching valve.
forming a relay port connected to the supply port of the switching valve, and communicating the downstream side of the relay port with the pilot chamber of the first switching valve;
When the first switching valve is in the normal position, the pump port and the outflow port are connected to each other, and when the first switching valve is in the switching position due to the pressure action of the pilot chamber, the actuator is configured to short-circuit the pump port and the relay port. Position control device.
