Abstract

See full text

The invention relates to systems and methods for rapidly and isothermally expanding gas in a cylinder. The cylinder is used in a staged hydraulic-pneumatic energy conversion system and includes a gas chamber (pneumatic side) and a fluid chamber (hydraulic side) and a piston or other mechanism that separates the gas chamber and fluid chamber while allowing the transfer of force/pressure between each opposing chamber. The gas chamber of the cylinder includes ports that are coupled to a heat transfer subassembly that circulates gas from the pneumatic side and exchanges its heat with a counter flow of ambient temperature fluid from a reservoir or other source.
