圧力制御弁。 A poppet 20 is provided in the valve body 1 with its outer circumference located at the primary port 11 connected to the load side and its tip located at the secondary port 12 connected to the tank side. 20 is biased in the valve closing direction by a compression spring 4 housed in the spring chamber 1b;
Further, a metering pin 30 is provided in the spring chamber 1b, and one end of the metering pin 30 is fitted into the poppet 20 with a slit, and the slit between the metering pin 30 and the poppet 20 is used as a diaphragm. The next port 11 communicates with the inside of the spring chamber 1b, and the other end of the metering pin 30 abuts against the end plate 13 that is accurately attached to the valve body 1, and the poppet 20
In this flow rate pressure control valve, the opening and closing of the poppet 20 is controlled by controlling the pressure in the spring chamber 1b with the pilot valve 5, while positioning the metering pin 30 with respect to the metering pin 30. The slit between the poppets 20,
A flow rate pressure control valve comprising a slit 21 provided in a poppet 20 and a land 31 provided on a metering pin 30 facing the slit 21.
