Abstract

A reciprocating opposed piston mechanism having at least one cylinder assembly mounted to oscillate in rotary relation to a block about a central axis, two opposing pistons reciprocally mounted within the cylinder, each of the pistons having an eccentric bearing mounted in its rear portion with an eccentric rotatably mounted in each eccentric bearing, each eccentric fixedly mounted to an eccentric shaft. Each eccentric shaft is mounted to the engine block and rotatable about an eccentric shaft axis equally spaced in opposite directions from the central cylinder oscillation axis. Timing mechanisms in force transmission relation to each of the eccentric shafts is provided to maintain the eccentrics in each cylinder assembly 180.degree. out of rotary phase. An even number of such cylinder assemblies, adjacently 180.degree. out of phase, may be assembled to form the mechanism of this invention. The mechanism is useful as an internal or external combustion engine, compressor or prime mover.
