ABSTRACT:
A rotary sliding vane fluid pump having an open rotor and radially extended arms forming slots that support the radially extending vanes. The relative position of the vanes and the inlet and discharge ports provide sealing by the vanes to the pump housing whereas the surface of the rotor does not seal to the pump housing so that radial rotor clearance is not critical. The rotor can be manufactured and assembled at lower cost. The rotor shape uses a minimum of material so that it is lower in weight and gives good pressure loading of the vanes. The open rotor is without closed voids to allow quick draining of the pump.
