Double-acting double pump principle: when the motor drives the rotor along the rotation, the blade under the dual action of centrifugal force and pressure oil at the bottom of the blade extends outwardly, the top of which is close to the inner surface of the stator. The four blades on the four concentric arcs, the outer surface of the rotor, the inner surface of the stator and the two valve plates respectively form four sealed working oil cavities. The oil chamber with the rotation of the rotor, sealing oil chamber produced from small to large or from large to small changes, can be through the valve plate oil suction window (connected with the oil suction port) or oil discharge window (connected with the oil discharge port) the oil suction or pressure out. In the process of each rotation of the rotor, each working oil chamber to complete two oil suction and pressure, so called double-acting vane pump, because the high and low pressure chamber symmetrical symmetry, axial force balance, for unloading type.
