Abstract: Described herein is a mechanism including: a driving shaft comprising an eccentric crank and an arm part extending radially from the driving shaft, the arm part of the driving shaft comprising a piston housing; a piston in the piston housing; an eccentric lever bushing comprising an arm part extending radially therefrom, a cylindrical outer surface and a cylindrical hole, wherein the cylindrical hole is rotatably attached to the eccentric crank, wherein an axis of the cylindrical hole and an axis of the cylindrical outer surface are parallel and offset; wherein the piston is configured to apply a torque on the eccentric lever bushing by pushing the arm part of the eccentric lever bushing. The driving shaft may further comprise a channel configured to apply fluid pressure on the piston. This mechanism may be used in a device such as a star scroll compressor.

Abstract: An apparatus has a housing having a prismatic interior chamber with a base of a shape of two partially overlapping circles; a first rotor and a second rotor rotatably fit in the prismatic interior chamber. The first rotor and the second rotor are configured to rotate in the same direction. The first rotor and the second rotor are prismatic in shape and the base of the first rotor has a first circular arc and a second circular arc. The first circular arc and the second circular arc are concentric. The first circular arc has a smaller radius than the second circular arc. The first circular arc and the second circular arc have the same central angle. The apparatus may function as a compressor or a pump.
