Claims

[Scope of utility model registration request]

(1) An /X housing having an oil suction passage and an oil discharge passage, both side surfaces in contact with two opposing parallel inner wall surfaces within this housing, and a cylindrical inner peripheral surface forming a hollow space in the center of this housing. a rotor having both side surfaces in contact with the inner wall surface in the space and rotationally driven around an axis eccentric to the center line of the ring; a plurality of vanes, each of which is provided with a plurality of vanes whose opposite ends are in sliding contact with the inner wall surface and whose radial outer ends are in sliding contact with the cylindrical inner circumferential surface of the ring; On one side, an oil passage is formed that communicates the oil discharge passage with a pump chamber surrounded by the cylindrical inner circumferential surface, the inner wall surface of the housing, and the rotor and partitioned by the vane, and the oil passage is The groove has a shape in which the cross-sectional area gradually increases from the vicinity of the position where the volume of the pump chamber is maximum toward the oil discharge path, and the vane is formed on the side surface where the groove is formed in the axial direction of the ring. A vane pump characterized in that the vane pump is biased radially outwardly by spring means at a position offset in a direction opposite to the vane pump.

(2) The vane pump according to claim 1, wherein the ring is made of a sintered alloy.

(3) The vane pump according to claim 1 or 2, wherein the ring is pivotally supported to be swingable about the center line of the ring.
