A Stirling type thermal engine is disclosed in which the engine is sealed within an outer shell enclosure which maintains the engine components in an axially compressed state to thereby simplifying construction of the engine while maintaining a sealed atmosphere of working fluid about the engine thereby minimizing leakage seal problems and also providing a containment enclosure about the engine in the event of explosive failure of the same.

In a thermal machine of the type including a machine body having a main axis extending between a thermal end and a work end, a working fluid at relatively high pressure in a working fluid chamber defined in said body and a displacer element reciprocable in said chamber for displacing the working fluid between a hot space and a cold space of said working fluid chamber for subjecting the fluid to a thermodynamic cycle in cooperation with a work piston, the improvement comprising outer shell means enclosing said machine body for maintaining at atmosphere of said working fluid about said machine body at a pressure substantially lower than in said working fluid chamber.
