Abstract
A cylinder body has a bore and an annular recess in communication with the bore. A piston is mounted for reciprocation within the bore, the piston having an annular skirt which reciprocates within the recess. A connecting rod has one end pivotally connected to the piston and the opposite end pivotally connected to a crankshaft for turning movement about an axis. A drive roller is rotatably carried by the crankshaft for turning movement about an axis. The drive roller is disposed in a cam groove in a flywheel which is drivingly connected to an output shaft. The two axes oscillate along two parallel arcs during reciprocation of the piston.
