EXTERNALLY HEATED ENGINE Russian patent published in 2003 - IPC

FIELD: mechanical engineering. SUBSTANCE: proposed invention makes it possible to increase efficiency of Stirling engines owing to complete elimination of leaks through rods of working pistons at absolute sealing of cylinders and engine. Externally heated engine contains at least one cylinder with heater, regenerator, cooler and lines connecting said units, and also working and displacement pistons and mechanism to convert translational motion rotation. Each cylinder is installed for translational displacement inside magnet or electromagnet and is coupled with mechanism converting translational motion into rotation. Each cylinder is installed in guides, and lines are furnished with bellows. Generator coupled with electromagnets by power cables is installed on one axis with crankshaft. EFFECT: increased efficiency of Stirling engines. 5 cl, 2 dwg
