量制御ロジツク弁。 A supply port to which pressure oil is supplied, an output port to discharge pressure oil, a poppet that connects and disconnects these supply ports and the output port, a control room that controls the movement of this poppet, and a control room that controls the movement of this poppet. A pilot flow rate is controlled by comprising a passage communicating between a control chamber and the output port, and a pilot spool interposed in the passage for opening the passage in response to pilot pressure and controlling the pressure in the control chamber. A pilot type flow control logic valve for controlling the flow rate of pressure oil discharged from the output port by means of a pilot type flow control logic valve, characterized in that a damper device for regulating the movement of the poppet is provided in the control chamber. .
