ABSTRACT:
In a vane pump a hollow cylindrical rotor (7) is mounted for rotation about its axis within a housing (1) and is arranged to be driven by a belt driven pulley (54) mounted on one end (19) of the rotor. Extending eccentrically within the rotor (7) is a shaft (11) which has its opposite ends (10) and (24) fixed in passages (9) and (23) respectively in the end portions (5) and (15) of the housing (1) so that the shaft (11) is not rotatable. The vanes (27) of the pump are rotatably mounted on the shaft (11) so that they extend axially of the shaft and project radially through axially extending openings in the cylindrical wall of the rotor (7). The vanes (27) are thereby rotated on the shaft (11) when the rotor is driven, and the portions of the vanes projecting through the cylindrical wall of the rotor sweep a pump chamber (13) surrounding a portion of the rotor to convey fluid from an inlet to an outlet of the pump.
