An improved crankshaft-driven internal combustion engine of the type having pistons reciprocable along an axis parallel to the crankshaft axis is described. Communication is effected, between the suction and exhaust ports of the engine and successive ones of the cylinders in which the pistons are mounted, by means of an apertured member supported for rotation on a crank having an axis parallel to and displaced from the crankshaft axis. The apertured member has opposed planar faces in engagement with the respective suction and exhaust ports and with the cylinders. A planetary gearing arrangement is associated with such apertured member and with the housing of the engine for orbiting the apertured member about the crankshaft axis as it rotates about its own axis. Compensating weights are suitably disposed on portions of the piston operating assembly, which assembly includes a wobble member mounted on a crank forming an acute angle to the crankshaft axis, and a connecting rod and ball joint assembly interconnecting the wobble member to each piston.
