ABSTRACT:
A two-stage rotating vane device comprising an outer stator defining a plurality of ports and an elliptically or cylindrically shaped interior cavity surface, with an inner stator defining a plurality of ports, the inner stator either being elliptically shaped or configured in a predetermined shape and located in the elliptically or cylindrically shaped interior cavity. A rotor is disposed in the elliptically or cylindrically shaped interior cavity between the interior cavity surface of the outer stator and the inner stator, the rotor defining a plurality of slots. A plurality of slidable vanes are situated in the plurality of slots for spanning between the interior cavity surface of the outer stator and the inner stator, and wherein a first stage is defined between the inner stator and the rotor, and a second stage is defined between the interior cavity surface of the outer stator and the rotor, the first and second stages communicating with each other. The present invention can be configured as a two-stage compressor, expander, or turbine engine, or combinations of these.
