摘要： Systems, methods and devices are described providing a selective hydraulic or electrically powered prime mover that is a (bi-directional power unit) PU system, including movement within a device or system used to compress and/or expand a fluid and provide fluid movement within the same device or system. The use of a (hydraulic power unit) HPU is involved and comprises at least a pump or other hydraulic fluid moving device often referred to as a “prime mover”, one or more first set of selective control valves delivering pressurized fluid to the device(s), and one or more second set of selective control valves returning unpressurized fluid from the device(s), a reservoir comprising a compensator tank, a port allowing for operation at ambient pressure, and a pressure measuring device measuring ambient pressure allowing for unbalanced flow to and from the mechanical (user) device as well as thermal expansion or compression.
