圧制御回路。 a poppet valve that is interposed in a flow path connecting one side of the actuator and the tank, has a spring that normally acts to close the flow path, and opens and closes the flow path by alternately applying pressure to a pair of opposing cylinder chambers; and the actuator. A cylinder port on one side connected to one side of the cylinder chamber that closes the poppet valve upon application of pressure, and a cylinder port on the other side connected to the other cylinder chamber are connected to a hydraulic source and a tank. Hydraulic control circuit consisting of a 4-port switching valve that is exclusively connected.
