The crankshaft of a crank mechanism has a projecting crank pin which is connected to an eye at the big-end of a connecting rod. An eye at the little-end of the connecting rod is connected to a gudgeon pin attached to the piston, being slidable axially of the gudgeon pin and being kept centered relative to the piston by resilient means. The eye at the big-end of the connecting rod is defined by a bush which is rotatably connected with the crank pin and has a pair of diametrically-opposing pins. The end of the connecting rod associated with the big-end is fork-shaped, and the arms of the fork are each articulated to one of the pins about a pivot axis which is perpendicular to both the axis of the crank pin and the longitudinal axis of the connecting rod. |
