Description

1131

The invention relates to mechanical engineering, namely engine building, and can be used to create heat engines operating along the Stirling cycle.

The purpose of the invention is to increase the power of the engine with an external heat supply.

FIG. 1 shows the basic layout of the engine; in fig. 2 - kinematic scheme of the engine in a conventionally disassembled length, isometric.

The engine consists of body 1, made in the form of two adjoining elements 2 and 3, each of which is closed by clamps 4 and 5, made in the form of spherical segments. The caps have partially spherical supports 6 and 7 with internal cavities D for their cooling and lubrication. The supports contain a drive shaft 8 with an inclined washer 9 in contact with the piston washers 10 equipped with blades 11 and seals 12. On. 4 and 5 opposite the blades 11; the grooves 13, into which the blades 11 go in and divide the volume of the body, into several hot K and cold L blades, connected to each other with an offset by rotation angle 8, through heaters 14, regenerators 15 and coolers 16, Engine supplied with combustion chamber 17, recuperator 18, feed 1 m 19 and 20 branch pipes, device 21 controlling the pressure in the internal cavity of the engine

Tel e and valve 22 refueling.

The device works as follows.

When the drive shaft 8 is rotated, the inclined washer 9, contacting the piston washers 10., gives them an oscillatory movement around the spherical supports 6 and 7, while the vanes 11 go in, the grooves 13, pimpled on the heads 4 and 5, volumes of hot. The K and cold L cavities vary from their maximum value to the minimum. One of the hot cavities K is connected to the cold cavity of L. che-o. cutting the heater, generator and cooler in such a way that the change in its volume is ahead of the change in the volume of the cold cavity by 60 in the angle of rotation of the shaft 8, the next hot cavity K, is connected in the same way

to the next cold cavity, L, etc. of the last pole, the cavity is connected to the first cold cavity, thus forming a six-cylinder engine with an external supply of heat of double action.

When the hot cavity K is reduced, the working fluid propels into the cold cavity L, giving heat to the regenerator and cooler — the working fluid is compressed. With a minimum volume of the hot cavity K, the main mass of the working fluid is concentrated in the cold cavity L, 5 is running out. Then the volume of the hot cavity K increases (and the volume of the cold cavity L decreases — the working fluid is pushed through the cooler, the regenerator and the heater into the hot cavity, and heat is collected in the regenerator and the heater. The pressure and temperature of the working fluid increase — an expansion cycle is performed. At the maximum volume of the hot cavity, the expansion cycle ends and the compression cycle begins. The process closes.
