特徴とするベーンポンプ。 In a vane pump in which a cam ring is sandwiched between a pump housing that forms a supply port and a discharge port, and a cover plate that forms a suction port, a pressure plate is installed inside the cover plate, which is the contact surface with the cam ring. A high pressure area is defined on the back side of this pressure plate, and high pressure on the discharge side is applied to this high pressure area, while a seal is fitted on either the pressure plate or the cover plate to define the high pressure area. A vane pump characterized in that a seal groove is formed, and the seal groove is formed by intersecting a plurality of circular grooves.
