Description

 The invention relates to engine building, namely to thermal engines, and can find application in those areas of the economy where high demands are made on environmental friendliness and versatility with respect to the energy source.

 Known Stirling engines containing two cylinders with two pistons. In one cylinder, air is compressed and displaced into a second cylinder, which is heated externally. There, air expands and pushes the working piston, and after that it is forced out into the cold cylinder. A portion of air continuously circulates between warm and cold cylinders, periodically changing its volume. The engine can operate from virtually any energy source (Stirling Engines. / Ed. By M.G. Kruglov. M .: Mashinostroenie, 1977, pp. 84-86).

 Closest to the proposed is an engine with an external supply of heat, comprising a housing with compression and expansion cavities, pistons, a refrigerator, a regenerator, and gas supply and exhaust systems.

 The disadvantages of such an engine include the problem of seals, the possibility of jamming of pistons, friction loss, noise level.

 The purpose of the invention is to increase reliability and efficiency by reducing friction losses and intensification of heat transfer.

 For this, an engine with an external heat supply, comprising a housing with expansion and compression cavities, pistons, gas supply and exhaust systems, a refrigerator and a regenerator, a working shaft, according to the invention, is equipped with a drum mounted on the working shaft using a one-way clutch and equipped with a reverse mechanism, a flexible sleeve is placed in the housing, one end of which is fixed on the drum, and the other is turned inside out and fixed in the housing; the housing is equipped with a nozzle in the cavity of which there is a refrigerator and a second drive reversing drum with the second sleeve wound on it, the end of which is turned out and fixed in the nozzle, the housing is in communication with the hot gas supply system and the gas removal system, the cavity formed by the turned part of the sleeve is in communication with the external environment, and the cavity formed in the pipe with the second sleeve filled with compressed gas or low boiling liquid, a limit switch is installed in the housing.

 The reverse mechanism of the first drum can be made in the form of a spiral spring.

 The reverse mechanism can also be made in the form of two drums rigidly connected to the first and second drums and interconnected by a flexible connection.

 In FIG. 1 shows a sectional view of an engine; figure 2 - the mechanism of the reverse of the drums.

 The device comprises a housing 1 with thermal insulation protection, in which the end 2 of the sleeve 3 is wound, mounted on a drum 4, mounted using a one-way clutch 5 on the shaft 6. The drum 4 has a mechanism for its reverse, for example a spiral spring (not shown in the drawing). On the housing 1 is fixed a pipe 7 made of heat-conducting material. In the pipe 7 there is a refrigerator 8, for example radiators. In the cavity 9 of the pipe 7, a drive reversing drum 10 is installed with a sleeve 11 wound thereon, the end 12 of which is fixed in the pipe 7. The cavity 13 is in communication with the gas removal system 14 and with the hot gas supply system 15. The cavity 9 is filled with compressed gas. The reverse mechanism of the drums 4 and 10 can also be made of two drums 16 and 17 (Fig. 2), which are rigidly connected to the drums 4 and 10. The drums 18 are wound in different directions on the drums 16 and 17. The cavity 9 can also be filled with low boiling liquid. In the cavity 13, a limit switch 19 is installed for the software mechanism 20, which controls the operation of the systems 14 and 15. Instead of the system 14, two holes 21 and 22 can be made in the cavity 13, through which the cavity is in communication with the external environment. The cavity 23 is in communication with the external environment.

 The device operates as follows.

 The system 14 serves cold gas, and the system 15 - hot gas into the cavity 13. The gas in the cavity 13 begins to expand and squeezes the sleeve 3 out of it, which is wound on the drum 4. The sleeve 3 starts to exit the cavity 13. After the sleeve 3 comes out half of it, sleeve 11 is introduced into it. Subsequently, sleeve 11 is introduced into cavity 13 faster than sleeve 3 is discharged from cavity 13. Gas in cavity 13 begins to cool by introducing sleeve 11. Gas in cavity 9 expands and cools, therefore it cools sleeve 11. A new cooling is constantly introduced into cavity 13 the given section of the sleeve 11. The gas pressure in the cavity 13 decreases and becomes less than the pressure of the external medium. By the pressure of the external medium, the sleeve 3 is pressed into the cavity 13. The sleeve 3 is cooled by the external medium. The environmental agent enters the cavity 23 and cools the gas in the cavity 13. The sleeve 3 rotates the drum 4, which transmits torque to the shaft 6. The sleeve 11 is removed from the cavity 13, winding it onto the drum 10. The gas in the cavity 9 is compressed and heated. Heat is removed from the cavity 9 by the refrigerator 8. The drums 4 and 10 can be reversed by winding the tape 18 onto one of the drums 4 and 10 and reeling it from the other drum. When the sleeve 3 presses the limit switch 19, the program mechanism 20 gives the command to open the systems 14 and 15 and supply gas to the cavity 13. The excess gas from the cavity 13 is squeezed by the sleeve 3 when the sleeve 11 comes off the opening 22. The hole 22 is closed by the sleeve 11 when moving sleeves 11 into the cavity 13.
