ABSTRACT:
At least two rotors are mounted in a chamber and rotate synchronously to compress and/or transport fluid. The chamber has the shape of partially overlapping circles with each circle intersecting the center of the adjacent circle. The rotors are non-eccentric and have curved sides with the same radius as the circles. In exemplary embodiments, the rotors are trochoidal and the chamber is epitrochoidal. Also provided are compressors, pumps, actuators, and engines incorporating the rotary machine.
