Apparatus defining an expansible/contractible chamber includes a housing having a first housing portion and a second housing portion. A rotor rotates within the first housing portion in one direction while a block rotates in the second housing portion in an opposite direction. A vane disposed on the rotor registers with a recess in the block and defines with the block the chamber. The apparatus can function as an engine, a turbine, a pump, a compressor, or a vacuum pump. An associated method includes the steps of introducing a fluid into the chamber, rotating the rotor and associated vane in order to vary the volume of the chamber and performing work relative to the fluid in the chamber. |
