御弁。closing a valve port between an inlet and an outlet with a piston valve, forming a pilot hole in the piston valve that communicates a pilot chamber inside the piston valve with the outlet through the valve port;
This pilot hole is closed with a pilot valve, and when the valve is opened, the pilot valve is separated from the pilot hole to open the pilot hole, and the pressure in the pilot chamber that occurs due to this opening is reduced, which causes the piston valve to be separated from the valve port. 1. A pilot type flow control valve which opens a valve port by moving the piston valve in a direction in which the piston valve is moved in a direction to open the valve port, wherein the piston valve is elastically biased in a direction away from the valve port by a spring.
