ルポケツトを形成したことを特徴とする２枚羽根
式油圧ベーンポンプ。 Two vanes are removably inserted into each vane groove provided in the rotor at an angle opposite to the rotational direction,
The surfaces of the vanes facing each other are formed with oil passages reaching from the bottom to the tip of the vane, and the suction pressure is applied to the bottom of the vane groove in the suction area, while the oil passage is applied to the bottom of the vane groove in the discharge area and intermediate area. In this two-blade hydraulic vane pump, each side plate is provided with an arcuate groove for guiding discharge pressure, and a recess is formed at the bottom of the rear surface of each vane on the side opposite to the rotational direction within each vane groove. A two-blade hydraulic vane pump characterized in that an oil pocket that opens toward the bottom of the vane groove is formed by the side wall of the vane groove and the side wall of the vane groove.
