ABSTRACT:
A heat-actuated heat pump is disclosed having liquid pistons which displace the working gas and transmit power between expanding gas and compressing gas. Power output from expanding sections is transmitted to compressing sections without intervening mechanical shafts or levers, and the phasing of the various pistons is self-regulated, thereby eliminating the need for phase control mechanisms, such as crankshafts. The engine and heat pump operate in a thermally regenerated cycle without valves, closely approximating a Stirling cycle.
