ENGINE WITH EXTERNAL SUPPLY OF HEAT Russian patent published in 2003 - IPC

FIELD: mechanical engineering. SUBSTANCE: invention relates to heat machines using for their operation principle of Stirling thermodynamic cycle. Said engine with external supply of heat contains sealed housing accommodating mechanism with cylinders, pistons and connecting rods. Said mechanism contains two cylinder blocks, namely, expansion and compression ones. Expansion cylinder block is located in non-heat insulated sealed chamber whose temperature is equal to ambient temperature, and compression cylinder block is located in heat insulated chamber. Cylinder blocks of compression and expansion chambers contains rocking plate mechanisms. Synchronization of rotation of said mechanisms is provided electrically by two electrical machines rotating in synchronism, namely, generator made to superconductivity technology rotated by rocking plate mechanism in heat insulated chamber and yielding main part of energy to consumer, and electric motor placed in non-heat insulated expansion chamber and rotating shaft of rocking plate mechanism. Sealed chambers are filled up with mixture of helium and power - like ice (snow) under pressure, helium in heat insulated chamber being in cryogenic state. EFFECT: increased efficiency of cycle . 2 cl, 1 dwg
