Parker hydraulic cylinder

Under the action of centrifugal force and pressure oil, the tips of Parker hydraulic cylinder blades are tightly attached to the inner surface of the stator. The working volume formed by the two blades and the inner surfaces of the rotor and stator first absorbs oil from small to large, and then discharges oil from large to small. When the blades rotate once, they complete two oil suction and discharge operations.

Parker hydraulic cylinderComposed of rotor 1, stator 2, blades 3, oil distribution plate, and end cap. The inner surface of the stator is a cylindrical hole. There is eccentricity between the rotor and stator. The blades can slide flexibly in the slots of the rotor. Under the centrifugal force during rotor rotation and the pressure oil flowing into the root of the blades, the top of the blades is tightly attached to the inner surface of the stator, forming sealed working chambers between two adjacent blades, oil distribution plate, stator, and rotor. When the rotor rotates counterclockwise, the blades on the right side of the figure extend outward, and the volume of the sealed working chamber gradually increases, creating a vacuum. Therefore, oil is sucked in through the suction port 6 and the window on the oil distribution plate 5. And on the left side of the picture. The blades retract inward, and the volume of the sealing chamber gradually decreases. The oil in the sealing chamber is squeezed out through another window of the oil distribution plate and the pressure port 1 and output into the system. This type of pump is called a single acting pump because it absorbs oil and pressurizes oil once during each rotation of the rotor. The rotor is subjected to radial hydraulic unbalance force, so it is also known as an unbalanced pump, and its bearing load is relatively high. Changing the eccentricity between the stator and rotor can change the displacement of the pump, so these pumps are all variable displacement pumps.
