摘要： A vane pump comprising vanes, a rotor carrying the vanes and which is rotatable about an axis, a housing, means defining a vane running path along which the vanes move, means defining a region of said path to be of non-constant radius relative to said axis and which varies the radius swept by the vanes as they pass along said region, an inlet port communicating with an inlet zone, an outlet port communicating with an outlet zone, a forward pumping zone between the inlet and outlet zones, a return pumping zone between the outlet and inlet zones, and means for varying the angular position of an end of one of the pumping zones in and relative to the area axially subtended by said region whereby to vary the displacement of the pump.
