A rotary drive mechanism for use as a motor, pump or compressor. The mechanism includes a housing having a chamber defined by a peripheral wall. A rotor is rotatably mounted in the chamber and has two longitudinal seal edges in contact with the wall. The rotor is mounted for rotation about a rotation axis and for sliding movement relative to the axis in a direction generally perpendicular thereto. The axis is offset from the center of the chamber. |
