Claims

[Scope of utility model registration request]

(1) A rotating shaft, a rotor rotated by the rotating shaft,
A large number of vanes are retractably fitted into vane receiving holes formed approximately in the radial direction of the rotor, a cam ring houses the rotor with the vanes attached, and a pump is mounted on the inner periphery of the cam ring. It has a front body and a rear body that form a chamber, and rotates the rotor.The vane fitted into the vane receiving hole of the rotor slides while being pressed against the inner peripheral surface of the cam ring. Due to the volume change between each vane, oil in the oil tank is guided into the pump chamber through the suction passage and suction port. In a vane pump configured to pressurize and discharge to the outside through a discharge port and a discharge passage, a ring-shaped side plate fitting portion is provided on four surfaces of the front body on the cam ring side, and the fitting portion A side plate, which is an annular plate as a whole and has a pair of discharge ports at substantially opposite positions in the diametrical direction, is fitted to the side plate to form a discharge passage between the front side body and the side plate. is provided with a convex portion near the discharge port to reduce the inner diameter fitting clearance with the front body, and a recessed portion that opens only on the inner diameter side on the cam ring side of the convex portion, and the front body and side A vane pump characterized in that a discharge pressure introducing groove is formed to introduce discharge pressure to the base end of the vane by using a fitting gap with the plate.

(2) The vane pump according to claim 1, wherein the side plate is formed of a sintered member.
