Abstract
A power system has a piston pump that is driven by high pressure gas from a high pressure gas source that alternatingly pressurizes a first gas chamber and a second gas chamber to drive a first piston and a second piston such that the piston pump pressurizes hydraulic fluid from a hydraulic reservoir into a hydraulic accumulator. The expanded high pressure gas from the piston pump is expelled to a low pressure gas outlet and the pressurized hydraulic fluid is used as a motive fluid to perform work.
