ABSTRACT:
In a free piston engine pump means are provided for obtaining a variable energy rate output and for controlling acceleration and deceleration of the piston masses. In particular a second high output work rate phase is obtained at the end of the power stroke helping to decelerate the piston masses, and a high input work rate phase is provided at the beginning of the return compression stroke to accelerate the piston masses while maintaining the total input energy of the return stroke relatively constant from cycle to cycle and substantially independent of the total output energy of the power stroke.
