STIRLING ENGINE WITH HERMETICALLY SEALED CHAMBERS Russian patent published in 2004 - IPC

FIELD: heat power engineering. SUBSTANCE: proposed engine contains displacement and actuating cylinders with hermetically sealed chambers connected by main line passing through thermal converters and motion transformer. Sealed chambers in displacement and actuating cylinders are interconnected by at least two main lines with gas-distributing mechanism making it possible to admit in turn hot gas into sealed chamber of actuating cylinder from gas main lines sealed chambers proper are made to change their volume, being made, for instance, in form of corrugations welded up of flat rings and provided with bottoms, bellows, packets, or made of elastic material. They are installed in liquid-filled cylinders to act onto motion transformer. Control over gas-distributing mechanisms is provided by electric, pneumatic, hydraulic or combination mechanism. Mechanical coupling with motion transformer is made either in form of rigid coupling-pusher, rod or rigid tie-rod, or hydraulic, or flexible, in form of cable, chain, cord, tape, belt, flexible pusher or combination one. EFFECT: optimization of gas flows, provision of hermetically sealed gas circuit for high pressure. 18 cl, 2 dwg
