Abstract
An internal combustion engine has means for stabilizing the position of a yoke and piston during the reciprocating movement. A pressure source transmits a force to one side of yoke to maintain the yoke in constant contact with a bearing surface on the wall of the crankcase, at the same time, the pressure source causes lubrication to be continually transmitted to a sliding block within the yoke at all positions of the crankshaft to lubricate the bearing between the crank throw and sliding block and the bearings between the sliding block and yoke to minimize wear during extended use. The yoke and piston are further stabilized in their reciprocating motion by a peg and ring configuration, one of which is mounted to the crankcase and the other mounted to the yoke. Twist of the yoke and piston about the cylinder axis is prevented by channels in the crankcase wall within which the yoke edges slide.
