The inner surface of the stator is composed of two large arcs, small arcs and four transition curves (1,2,3,4). The stator and the 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 and lower left corners, the volume of the sealed working chamber gradually increases, which is an oil suction area; in the lower right and upper left corners, the volume of the sealed working chamber gradually decreases, which is an oil pressure region.
An oil sealing area between the oil suction area and the oil pressure area separates them. Each time the rotor rotates once, each blade slides back and forth twice, and the volume of each closed working chamber is circulated twice, and it is enlarged and reduced twice , Complete the role of the pump, called a double-acting vane pump. In addition, the pump’s two oil inlet chambers and outlet pressure oil chambers are radially opposed, so the rotor is hydraulically balanced, and the bearings are not subject to hydraulic loads. This ensures long life.
The rotor rotates once, the oil is sucked twice between the two blades, and the oil is drained twice, each time the volume is M; when the number of blades is z, the displacement of all the blades of all the leaves in a week is 2Z M volumes. This value is exactly twice the ring volume.
