Ｊ　ＩＪ−フ弁内蔵型流量制御弁装置。A movable spool valve is provided which communicates with the pump discharge port and bypasses the surplus flow of the pump discharge liquid to the pump suction port side so as to keep the pressure difference before and after the orifice constant, and the orifice is connected to one end of the spool valve. A pressure chamber is formed having an inlet in an end wall into which the pressure liquid after passing is introduced, and a spring is interposed between the end wall and the spool valve, and the liquid pressure in the pressure chamber is lowered to a set value or less. In the flow control valve device with a built-in pressure relief valve, the pressure relief valve is provided inside the spool valve, and the pressure fluid inlet is covered with the end wall of the pressure chamber, and the pressure relief valve is provided with a pressure relief valve inside the spool valve. Pressure I characterized in that a small diameter filter is pressed by the spring.
J IJ-Flow control valve device with built-in valve.
