Abstract
Abstract In an engine having at least one cylinder block which comprises a plurality of radially extending cylinders with a respective piston (130) reciprocally mounted in each of the cylinders, means for interconnecting the pistons in such a manner as to provide a substantially vibration-free engine having no flywheel comprise a crank bearing ring (117), to which connecting rods (119) for the pistons (130) are pivotally connected by pins (118). The crank bearing ring (117) is arranged to drive a crank (106) and is mounted for relative rotation with respect to the crank. Gearing (121, 122, 123, 124) is arranged between the crank (106) and the crank bearing ring (117) and the ratio of the gearing is such that the ring (117) and crank (106) rotate at the same speed but in opposite directions. <IMAGE>
