A rotary pump of the stationary single vane type wherein the vane is arranged to automatically accommodate for the direction of rotor rotation to provide for the flow of fluid through the pump in a single direction regardless of the direction of rotor rotation, the vane also being operable to automatically relieve excessive pressures in the pumping chambers.


A rotary pump comprising: a housing having an inner peripheral surface defining a cavity; a rotor having an outer peripheral surface disposed in said cavity; means for rotating said rotor in said cavity, said rotor and cavity defining between said inner and outer peripheral surfaces a rotating pump chamber having a volume which increases and decreases as said rotor is driver; a fluid inlet passageway comminicating with said cavity; a fluid outlet passageway communicating with said cavity; and single vane means normally sealingly engaging the entirety of ...
