Claims

[Claims for Utility Model Registration] A housing having an oil suction passage and an oil discharge passage, and a cylindrical interior that forms a space in the center of the housing and on both sides that are in contact with two opposing parallel inner wall surfaces within the housing. a ring having a circumferential surface; a rotor whose both side surfaces contact the inner wall surface within the space and is rotationally driven around an axis eccentric to the center line of the ring; and a rotor that is slidable in the radial direction around the outer circumference of the rotor. a plurality of vanes provided in the ring, the opposite ends of which are in sliding contact with the inner wall surface, and the radially outer ends of which are in sliding contact with the cylindrical inner circumferential surface of the ring, the oil suction passage and the oil discharge passage being in the space; The suction and discharge port portions communicating with each other are concave grooves formed in an arch shape along the outer periphery of the rotor on the inner wall surface of the housing, and the concave grooves are formed on the side end surfaces of the vanes. an inclined surface that slopes in a direction in which the width of the vane decreases radially outward in a range facing the groove; and a flat surface that extends parallel to the inner wall surface of the housing in a radially inward direction from the contact range. A vane pump characterized by being formed with.
