ーンポンプ。 By rotationally driving a rotor having vanes within the pump body, a pump chamber formed in a cam ring that houses the rotor is moved from a pump suction side passage that opens on the upstream side in the rotational direction to the downstream side in the rotational direction. In a vane pump that sucks and discharges pressurized fluid into an open pump discharge side passage, an open end is connected to the pump suction side passage that opens into the pump chamber, and the pressure fluid flows from the passage in the direction of rotation by the rotor of the pump chamber. A vane pump characterized in that the opening of the passageway is inclined at an end face along a line.
