A Metal Bellows Expansion Engine
In 1954 Long and Simon  constructed a metal bellows expansion engine for cryogenic service. The two major factors which limited the further development of this engine were the early failure of the bellows from fatigue, and the difficulty in properly filling the clearance volume inside the convolutions of the bellows. Recent advances in the construction of welded metal bellows have opened the possibility of significant progress in the development of such an engine.
