! VANE PUMP
The vane pump consists of a rotor, a cam ring, and ten vanes.
When the rotor rotates, the vane movably fitted in each slot of the rotor is radially moved out by
centrifugal force and pressed against the inside wall of the cam ring. Since the inside of the cam
ring is oval-shaped, the fluid from the suction port is confined and pressurized in the chamber
formed between two adjacent vanes as the rotor rotates and is delivered through the discharge
port. The pressurized fluid circulates through the hydraulic circuit.
