A piston machine with at least one axially movable piston in a cylinder is designed with a force conversion mechanism implying sinusoidal piston movement by rotation of the power input or power output shaft of the machine, depending on its application, as the pistons of the machine are fastened perpendicularly to crosshead yoke (5) at their preferably light, cylindrical piston-rods (2, 2'), in which two crosshead slides (14, 14') each are provided on a crank pin journal (7, 7'; 8, 8') which is synchronized to perform rotation with mutual opposite directions of rotation (indicated as arrows), which causes that the crosshead slides longitudinally in the yoke are moved in exact mutual opposition and both reverse their direction of movement on the exact same time, whereby it is achieved that the lateral pressure on pistons is completely eliminated and that without any addition of any extra balancing mechanism there may be achieved a complete outbalancing of the reciprocating and rotating masses in the machine. |
