。 A pump housing, a cam ring housed in the pump housing, a pair of side plates arranged on both sides of the cam ring and each having a suction port and a discharge port formed on the surfaces facing the cam ring, and a pair of side plates that slide on the cam surface of the cam ring. A rotor that holds a plurality of contacting vanes on the circumference,
an end cover having a receiving surface facing the back surface of the one side plate and fixed to one end of the pump housing; two ring grooves are formed on the back surface of the one side plate;
In a vane pump in which a pressure introduction hole is formed in the side plate to insert a ring and introduce discharge fluid into a pressure action chamber formed between the O-ring, the side plate, and the end cover, the axis line is always attached to the side plate at the center. A relief hole penetrating in the direction is formed, a discharge groove in which the relief hole and the suction port communicate with each other is formed in a side plate or an end plate, and the O-ring is arranged in a semicircular shape on both sides of the discharge groove. Features a vane pump.
