ABSTRACT:
A compact free piston engine of the unsymmetrical type including a structure with a cylinder detachably supported therein, said cylinder having a pair of pistons with a combustion chamber therebetween and each piston having a rod extending through the adjacent end of the cylinder and having motion reversing means at one end of said cylinder and extending between said rods. Preferably, the structure is of strong but lightweight construction. It may have a skeleton type of housing with bolt type columns spaced around the cylinder. Portions of the reversing means lie along the side of the cylinder while another major portion thereof lies beyond one end of the cylinder. An energy absorbing device or devices may be connected to one only or to each of the rods, and each rod will be driven simultaneously in an opposite direction to the other by both pistons.
