Technical Examples

An Internal Combustion Engine including a plurality of reciprocating pistons disposed about the periphery of a central housing, and a pair of drive cams responsive to the displacement of the pistons for driving one or more output drive shafts. A piston rod cross member engages cam raceways of a pair of drive cams. Each raceway comprises a plurality of lobes defining power and compression stroke surfaces. Axial displacement of the cross member within the raceway effects rotation of the drive cams and output drive shafts which are rotational coupled to each drive cam. The drive cams and output drive shafts may rotate in the same or opposite directions, delivering high torque at low rotational speeds and, in one embodiment providing a torque-balanced output. Furthermore, the drive cams may include peripheral teeth for driving a timing gear which is timed relative to the output drive shafts for driving auxiliary equipment.
