ABSTRACT:
A free piston engine having a pair of opposed power cylinders and pistons on a common longitudinal axis with an energy absorbing device, such as a compressor piston, being directly connected to one of the power pistons and indirectly connected to the other power piston by means of a motion reversing, synchronizing and counterbalancing mechanism on said axis. The cylinders are arranged to be fired simultaneously and due to the face that the forces from the power pistons acting on the reversing mechanism are balanced, the forces on the bearings in the mechanism are substantially reduced over those occurring in machines having cylinders that fire 180.degree. out of phase, which results in a minimum of wear and higher efficiency due to the reduced friction. The engine can also have a bounce chamber therein which gives better control and more stable operation of the power pistons than found in engines with alternately acting pairs of power pistons which do not require power piston returning means.
