Abstract

The invention makes it possible to increase the power of the Stirling engine. The engine comprises a stanina 1, a hot 2 and a cold 3 cylinders, a crank mechanism 4, a working 7 and a pushing 8 pistons located in the cylinders and forming in them the first cavity 9 compression, the second a compression cavity 10 and an expansion cavity 12, a main 14 connecting the compression cavities to a regenerator 15, made in the form of a gap between the cylinder 2 and the piston 8 and communicating the cavities 10 and 12, the heater 16 and the air-cooled cooler 17. With the burner 18 lit, located under the heater 16, heat is supplied to the working fluid. When the piston 7 is in the TDC, the main mass of the working fluid concentrates in the hot cavity 12, the temperature and pressure of the working fluid are maximum — the expansion process starts. When the piston reaches 7 NMT, the expansion process ends and starts the compression process, which proceeds with heat extraction in the cooler 17 The displacer piston 8 does not perform work, but carries out the distribution of the working fluid across the engine cavities in the processes of compression and expansion. The rotation of the shaft of the crank mechanism and the movement of the piston 7 create additional convection of the air washing the cooler, due to which there is more intensive cooling and, as a result, an increase in engine power. 2 Il. w fe

Claims (1)

Claim A Stirling engine containing a bed, hot and cold cylinders mounted on it, a crank mechanism with a crankshaft and a flywheel fixed to the bed, connected to the working and displacement pistons located respectively in the cold and hot cylinders, with the formation of the first compression cavity in the cold cylinder and with the separation of the hot cylinder into a second compression cavity enclosed between. the bottom and the piston, and the expansion cavity enclosed between the cylinder cover and the piston, a line connecting between 4744293 are cavities, compressions, a regenerator installed in a hot cylinder and communicating the second cavity with a compression cavity and an expansion cavity, a heater adjacent to the expansion cavity, and an air cooling cooler adjacent to the second compression cavity, characterized in that, in order to increase power due to intensification of heat removal from the cooler by creating additional convection of air, the bed is made in the form of two plates perpendicular to the axis of the crankshaft. 'the cold cylinder is located on the lateral 5 surfaces, and the combustible-ator surfaces of the plates, and the crank mechanism is located between the plates, and the plates are made integral with the bottom of the hot cylinder.
