A rotary vane pump comprising a stator (10) having a cylindrical outer surface (23); a rotor (2) which is substantially annular and positioned around the stator to define a fluid chamber (24) between the rotor and the stator, the rotor being rotatable about a longitudinal axis and having a number of radially extending slots (12) therein; a vane (11) slidably mounted in each slot and biased towards the fluid chamber and into engagement with the outer surface of the stator, the vanes reciprocating in their respective slots as the rotor rotates about the stator; a fluid inlet connecting with the fluid chamber; and a fluid outlet connecting with the fluid chamber. Improved efficiency and quieter design. <IMAGE> |
