An equal diameter cam is mounted on the output shaft of an internal combustion engine or drive shaft of a piston-type compressor. A piston is joined by a connecting rod to a frame carrying two equal diameter follower rollers engaging the surface of a cam and located at diametrically-opposite points on a line through the center of rotation of the cam. A control arm can be used to control the position of a follower roller. The rotational axis of each follower roller is spaced by the cam surface from the rotational axis of the drive output shaft to transmit torque by converting reciprocating motion impressed by the follower rollers on the cam surface according to the equation:
