。 A pipe whose insertion depth can be adjusted arbitrarily is installed in an orifice drilled at the tip of the connector on the spool valve side, with one end opening into the pressure chamber and the other end opening into the discharge passage communicating with the actuator. A flow control valve characterized in that a restriction passage is formed on the spool valve side of the connector to provide flow resistance to the hydraulic oil flowing from the introduction part of the spool hole toward the pressure chamber.
