Abstract
The motion translation mechanism of the invention includes a crankshaft having a crank arm with an integral eccentric pin. A circular linkpiece is provided which has an opening positioned eccentric to the center axis of the circular linkpiece and positioned within the circular linkpiece eccentric opening. A displacement member with flat bearing surfaces is mounted for reciprocating motion and has a circular opening. A first thrust converting means secured to the circular linkpiece, as well as, second and third thrust converting means that come into consecutive contact with the first thrust converting means. The circular linkpiece is positioned within the circular opening of the displacement member, whereby reciprocating motion transmitted to the displacement member is converted to rotary motion of the crankshaft via the apparatus just enumerated.
