Abstract (en)

[origin: WO9638654A1] A motor/pump (10) comprises a housing (12) defining a cavity (18) between sealed ends (14 and 16). Rotor (24) having a substantially hollow body (26) is supported by the housing (12) for rotation within the cavity (18) about a rotation axis (28) which is parallel to but offset from longitudinal axis (30) of the cavity (18). A plurality of vanes (32) are retained by the rotor (34) for movement radially of the rotation axis (28). The vanes (32), rotor (24) and housing (12) are juxtaposed so that a substantially sealed chamber is formed between adjacent vanes (32), inner surface (34) of housing (12) and outer circumferential surface (36) of the rotor body (26). First and second ports (20, 22) are formed in the housing (12) and located so as to be disposed in different chambers. A split sleeve (122) is disposed within the rotor (24) for biasing the vanes (32) radially outwardly from the rotation axis (28) wherein axially opposite ends of said vanes (32) are disposed inboard of opposite first and second ends of said rotor body so that in use only a length of said axially opposite ends of each vane which extend beyond an outer peripheral surface (36) of said rotor body can slidingly contact respective adjacent ends of said housing (46, 56).
