Coolant penetrating cold-end pressure vessel

摘要: An improvement is provided to a pressurized close-cycle machine that has cold-end pressure vessel and of the type having piston undergoing reciprocating linear motion within cylinder containing working fluid heated by conduction through heater head heat from an external thermal source. The includes exchanger for cooling fluid, where disposed vessel. may be directly coupled welding or other methods. A coolant tube used convey exchanger.
