Patent ID: 8322316

Claim:
An engine having an output shaft for providing rotary motion, the engine comprising: first and second mounting plates; a camwheel rotatably mounted to the output shaft for supplying rotary motion thereto, the camwheel being disposed between the first and second mounting plates; a plurality of cylinders straddling the guiderail, the plurality of cylinders being interposingly coupled between the first and second mounting plates in a static circular plane about the camwheel such that a radius of the circular plane and the camwheel are coplanar; and a corresponding plurality of pistons disposed within each of the plurality of cylinders, each of the corresponding plurality of pistons including: a connecting shaft for coupling a drive bearing thereto, the drive bearing for engaging and maintaining contact with the camwheel, and opposingly mounted journals on the connecting shaft, the opposingly mounted journals for ensuring the drive bearing maintains its position, wherein the rotary motion is obtained by transferring displacement of the plurality of pistons from respective top dead center positions and bottom dead center positions to the camwheel, thereby rotating the camwheel.
