PV7

The centrifugal force resulting from the rotation of the shaft pushes the blades in the grooves of the rotor outward and keeps them in contact with the surface of the rim. In the first half revolution of the shaft, the space between the rotor and the cam ring increases. Increasing the volume of the gap causes pressure to decrease and create suction, which causes the fluid to flow towards the pump inlet duct. In the second half cycle, the blades gradually return to the groove following the surface of the cam ring, and due to the reduction in volume, the fluid is pushed towards the outlet channel. If the eccentricity between the axis of the rotor and the cam ring reaches zero, there will be no more current at the outlet. Some vane pumps, whose eccentricity can be adjusted by a mechanism, are known as variable displacement pumps (such as Rexroth's PV7 pump). In such pumps, the amount of eccentricity can be adjusted by moving the cam ring by manual adjustment or pressure compensating mechanism.
