容量形ベーンポンプ。A rotor having a large number of vanes is housed inside a movable ring that is movable in the radial direction within the inner hole of the pump housing, and the movable ring is biased to one side by a spring member that is in contact with the outer periphery of the movable ring. a fluid chamber formed between the inner circumference of the inner hole of the pump housing and the outer circumference of the movable ring and between the inner circumference of the movable ring and the outer circumference of the rotor. In a variable displacement vane pump having a discharge port communicating with a discharge area of a pump chamber and a discharge hole communicating with the outside, the movable ring is inserted between the discharge port and the discharge hole in the inner hole of the pump housing. A seal portion is provided in close contact with the peripheral wall in a fluid-tight manner, and an orifice is formed in a recess provided on the opposite side of the inner hole peripheral wall of the pump housing to the outer periphery of the movable ring. A variable displacement vane pump characterized in that a gap adjusting member configured to reduce the opening degree of the orifice in accordance with the displacement of the movable ring is attached to the outer circumference of the movable ring through a spring member so as to be movable toward and away from the outer periphery of the movable ring.
