ENGINE WITH EXTERNAL SUPPLY OF HEAT Russian patent published in 2000 - IPC

Abstract RU 2157459 C1

FIELD: mechanical engineering; external heating machines. SUBSTANCE: invention relates to heat machines operating to thermal Stirling cycle, i.e. isotherm- isochore-isotherm-isochore in ideal case. Proposed engine with external supply of heat consists of three chambers A, B, and C connected to form hermetically sealed system. Chambers A and B are heat insulated. Chamber C with wall featuring high thermal conductivity is exposed to ambient temperature. All three chambers are filled with hydrogen of different phase states. Chambers B is loaded additionally with metal hydride powder. Chamber C is located higher than chamber A. Chamber A is constantly filled with liquid hydrogen. Chamber B id initially filled with liquid hydrogen which changes into gaseous state in process of plant operation. Heat power plant mechanism is arranged in chambers A and C. It is formed by shaft passing through chamber A and C and expansion and compression cylinder blocks with pistons and connecting rods. Each pair of coaxial cylinders in blocks is connected by short pipelines with built-in regenerators. Compression cylinder block is kept in liquid hydrogen in chamber B, and expansion cylinder block is kept at temperature of ambient medium in chamber C. Working medium inside cylinders is hydrogen in gaseous state. Phase shift between connecting rod and piston groups of coaxial cylinders is 90 degrees which approximately provides realization of Stirling thermodynamic cycle. Invention provides self- contained fuelless ecologically clean power plant highly compatible with internal combustion engines. EFFECT: enlarged operating capabilities. 13 cl, 4 dwg
