ABSTRACT:
A rotary vane pump is provided which comprises a cylindrical housing, and a cylindrical rotor mounted within the housing. The rotor includes a number of radial guide slots extending axially along the length of the rotor, with each slot having a depth along at least a portion of its axial length which extends to the axis of the rotor. A blade is slideably disposed in each slot, and has a height which generally corresponds to the depth of the slot. This arrangement permits the rotor to be compact in size, and yet able to provide an adequate area of contact between the blades and rotor slots in the extended position of the blades.
