Equipped with an actuator that rotates and adjusts the
In a variable displacement oil pump, the cam ring is rotated by the actuator to change the amount of eccentricity between the inner periphery of the cam ring and the rotor, thereby controlling the discharge amount of the pump relative to the pump discharge pressure. A variable capacity oil pump in which the vane is swingably held by a plurality of groove-shaped fulcrums provided on the outer periphery. (2) The variable displacement oil pump according to claim (1), further comprising a sliding ring that is close to the outer end of the vane and close to the inner peripheral surface of the cam ring.
