Abstract
A sliding vane pump is provided including a pump assembly having a housing with a fluid inlet and a fluid outlet formed therein, a lining member received in the housing defining a substantially cylindrical inner surface and a rotor arranged inside the lining member, defining a substantially cylindrical outer surface. The inner surface of the lining member and outer surface of the rotor define a working space therebetween. The pump assembly also comprises a plurality of vanes received in slots formed about the rotor outer surface. Each vane is arranged to slide in the radical direction with respect to the rotor such that an outer edge of the vane contacts the lining member inner surface, thereby dividing the working space into working chambers. Rotation of the rotor draws fluid from the fluid inlet working into the working chambers, which is ejected into the fluid outlet.
