In machines incorporating reciprocating pistons or the like and rotating crankshafts, the above two components are conventionally coupled by a rigid link, conventionally termed a "connecting rod". This connecting rod is conventionally designed so that it is symmetrically shaped, in the plane of rotation, about an axis which passes through the central axis of the piston/cylinder and through the crankpin axis. This connecting rod axis is analogous to its thrust axis. In this proposal, the shank of the connecting rod is offset, in the plane of rotation, progressively towards its crankpin end. This results in its thrust axis also being offset from the conventional central/symmetrical position, and in the thrust axis consequently lying either within or outside the crankpin centre trajectory at different parts of the rotational cycle. The resultant geometry confers significant benefits in that an increased mechanical advantage is imparted at certain parts of the cycle, and an improved thrust angularity similary. These factors confer a significant increase in power and torque, and improved economy of operation. The sense of the offset (advanced or retarded) and the timing of the above benefits will depend upon the application - driving machines such as internal combustion engines, or driven machines such as pumps or compressors.
