The stator and rotor are concentric. The four oil distribution windows on the oil distribution pan communicate with the suction and pressure ports, respectively.
When the rotor rotates clockwise, the blade embedded in the rotor slot (which can be flexibly slid) is under the action of centrifugal force and pressure oil, and the top is tightly attached to the inner surface of the stator. In this way, the stator, the rotor, the slidable blades, and the oil distribution plate constitute a plurality of closed working chambers with variable volumes. In the upper right corner and the lower left corner, the volume of the sealed working chamber gradually increases, which is an oil suction area; in the lower right corner and the upper left corner, the volume of the sealed working chamber gradually decreases, which is an oil pressure region.
