STIRLING ENGINE Russian patent published in 1994 - IPC

FIELD: engine engineering. SUBSTANCE: pipes 12 of a heater of a working wheel enclose differential hot cylinder 3 and are coupled to expanding space 10 through first 13 and second 14 rows of radial passages made on cupola-shaped part 4 of differential cylinder 3. Combustion chamber 17 encloses pipes 12 of the heater and is adjacent to a case of regenerator 15 which encloses middle part of cylinder 3. Nozzles 18 are arranged over periphery of combustion chamber 17 in a region where it is abutted on case of regenerator 15. A space for an additional heater of working medium 20 is formed between the wall of heat cylinder 3 and cover 8 of displacement piston 7. The space is connected to regenerator 15 through third 21 row of the radial passages. The flowing section of the passages is in the range 25-35% of area of pipes 12 of the heater. . EFFECT: increased surface of the heater and adding additional heat to the engine cycle. 1 dwg
