Abstract
A rotary device for use with a fluid, having a housing, a rotor, and a vane having a respectively associated wiper. The housing has a tubular surface defining in part a tubular volume, the tubular volume segregated into at least a pumping zone and a working zone. The rotor is mounted for rotation and has a body mounted within the tubular volume and a plurality of slots. Each slot extends at least generally radially from the axis. Each vane is mounted at least partially within each slot. As the rotor rotates, each vane rotates within the tubular volume and extends and retracts within the tubular volume. The wiper contacts the tubular volume of the housing while the respectively associated vane rotates through the pumping zone, and wherein the wiper does not contact the tubular volume of the housing while the respectively associated vane rotates through the working zone.
