The energy conversion system of the subject invention converts the energy from a source of pressurized fluid, such as a free-piston engine and a storage accumulator, to a work system at various pressure levels. This is accomplished by providing power modifying units which act to efficiently reduce the pressure level of the fluid from the source of pressurized fluid to the various pressure levels. A control arrangement monitors the operating pressures in the actuators and selects the path of pressurized fluid having the lowest pressure level needed to perform the task. Additionally, exhausted fluid containing energy is utilized by regenerating the fluid back to the inlet of the actuator or by directing it through the appropriate power modifying unit to amplify the pressure therein and supplement or recharge the source of pressurized fluid.
