量制御弁。 A spool and a cylindrical member are installed in series in the valve hole formed in the valve body, and a spring is applied to the outer end of the spool. Normally, the spool comes into contact with the tip of the cylindrical member to open a bypass passage. A fixed orifice is formed in the cylindrical member to communicate the inflow port and the outflow port, and the cylindrical member is provided with a plunger that moves according to the differential pressure before and after the fixed orifice for flow control. In the valve, a variable orifice port separate from the fixed orifice is formed in the cylindrical member, and when the plunger is in a normal position, the variable orifice port is blocked, and the plunger is moved by a pressure difference before and after the fixed orifice. A flow control valve configured to open the variable orifice port when the variable orifice port is opened.
