Abstract
A free piston engine pump which utilizes plural hydraulic piston areas or hydraulic pressures, with suitable valving to properly "phase" these areas or pressures during the engine stroke, to generate plural hydraulic work rates in order to smooth out the energy or work rate of the free piston engine and minimize the inertia-storage of energy required.
