Beschreibung
Zusammenfassung:	[Object] To provide a flow control valve in which the force exerted by the differential pressure to be applied to a valve member is reduced effectively.[Solution] A flow control valve 1 includes a bottomed cylindrical base member 10 having a valve chamber 13, and a valve member 6 placed in such a manner as to face a valve port 15 formed in a bottom wall portion 12 of the base member 10. A back pressure chamber 23 separated from the valve chamber 13 is formed outside the base member 10. The base member 10 includes a base body 11 having an inflow port 19 that is open on a valve chamber 13. The bottom wall portion 12 of the base member 10 has a flow channel 16 that is continuous with the valve port 15, and a pressure equalizing hole 17 through which the flow channel 16 is connected to the outside of the base member 10. When viewed in a facing direction in which the valve member 6 and the valve port 15 face each other, the pressure equalizing hole 17 is shifted from a position that is on a center line M of the inflow port 19 and that is opposite the inflow port 19.
