Abstract
A rotary device for use with a fluid includes a housing, a rotor, a ring, and at least one vane. The housing includes a tubular surface defining, in part, a tubular volume. The housing is segregated into at least a pumping zone positioned between first and second working zones. The first working zone is configured to receive a fluid and the second working zone is configured to output the fluid. The rotor is mounted for rotation about a rotation axis. The rotor includes a body mounted within the tubular volume. The body includes a plurality of slots. The ring is at least indirectly coupled to the housing by way of a bearing. The at least one vane is associated with one slot of the plurality of slots. The at least one vane is connected at least indirectly to the ring and configured to rotate within the tubular volume.
