In a variable displacement vane pump, the discharge amount of the pump is made variable by rotating the cam ring by the actuator to change the amount of eccentricity between the inner periphery of the cam ring and the rotor, and an orifice is provided in the discharge passage of the pump. The actuator is actuated by the differential pressure across the orifice, and the orifice is a variable orifice whose opening area changes according to the differential pressure across the orifice. −
