る流量制御装置。 a housing having an inner hole in which an inlet communicating with a discharge port of the pump and a bypass port communicating with a suction chamber or a reservoir of the pump are opened; a pressure chamber that communicates with the inlet and an outlet formed at one end of the inner hole through an orifice; and a spring that is tensioned at one end, the other end of which is locked to the other end of the inner hole. and a spool valve forming a back pressure chamber with which the working fluid on the outlet side of the orifice communicates via a fluid passage, and the pressure difference between the pressure chamber and the back pressure chamber causes the A flow rate control device in which a spool valve is moved within the inner hole to open and close communication between the bypass port and the pressure chamber to control the flow rate delivered from the outlet, and the orifice is positioned at the axis of the inner hole. 1. A flow rate control device, characterized in that the inlet is formed on the inner hole, and the axial center of the inlet is shifted from the axial center of the inner hole.
