·
OSTI ID:6906335
A method is described of operating a hot gas engine comprising a cylinder having one end thereof connected to the other end thereof through at least two separate closed heat exchanger assemblies. Each comprises heated heat exchanger means and cooled heat exchanger means serially arranged, the hot end of each such closed heat exchanger assembly is attached to the same end of the cylinder. Each closed heat exchanger assembly is equipped with valve means at each end thereof, the cylinder accommodating a double-acting reciprocating piston means. The piston means cyclically displaces and is displaced by a volume of gas for each such closed heat exchanger assembly. The volumes of gas are alternately confined in and released from the closed heat exchanger assemblies by the valves.
