ABSTRACT:
A free piston engine has a pair of opposed cylinders on opposite sides of a fluid pumping assembly. An inner piston assembly includes a pair of inner pistons, one each in a respective one of the cylinders, with a push rod connected therebetween. The push rod forms a fluid plunger. An outer piston assembly includes a pair of outer pistons, one each in a respective one of the cylinders, with a pull rod connected therebetween. The pull rod forms a fluid plunger. The movement of the inner and outer piston assemblies during engine operation will cause the fluid plungers to pump fluid from a low pressure container into a high pressure chamber as a means of storing the energy output. A hydraulic coupler synchronizes the inner and outer piston assemblies.
