量形ベーンポンプ。A movable ring is housed in the inner hole of the pump housing so as to be movable in the radial direction, a rotor having a large number of vanes is rotatably housed within the movable ring, and a spring is provided to press the movable ring in the radial direction. , a circumferential space between the inner hole of the pump housing and the outer surface of the movable ring is used as a pressure fluid flow path, and the movable ring is moved against the spring by the fluid pressure of the flow path. In a positive displacement vane pump, the movable ring is placed in direct contact with the inner hole of the pump housing by the spring to determine the maximum eccentricity of the movable ring, and the contact portion between the movable ring and the pump housing is A variable displacement vane pump in which a notch for securing the flow path is formed in either the outer surface of the movable ring or the inner hole of the pump housing.
