Abstract

A vane pump (1) is provided comprising a housing (6, 30) having an inlet (7) and an outlet (8) with a hollow rotor and vane mechanism (9) therebetween. The vanes (12) are confined to movement radially in an out of the rotor (10) according to a cam and cam follower assembly associated with the housing and vanes. A fluid inlet (26) is provided for operatively connecting a supply of fluid of fluid under pressure to the interior (11) of the rotor. Preferably, the cam and cam follower assembly is arranged such that a vane remains at a substantially fixed degree of extension from the rotor during substantially the entire pumping 'stroke'. Also preferably, the outer edge of a vane cooperates with the surface of a wear resistant insert (22) fitted into an accommodating recess in the housing and the rotor has each of its two ends confined to rotational movement by means of wear resistant bushes (25). The pump preferably has an electric motor (28) and gearbox (29) assembly with the axis of rotation of the electric motor extending radially with respect to a drive shaft (27) of the rotor.
