SU7308A1 - Engine running steam or internal combustion - Google Patents

Description

The proposed engine operating by steam or internal combustion is shown in the drawing, in which FIG. la schematically depicts a diametrical section of the cylinder and a partial view of the crank mechanism, and FIG. 1, 2, 3,4-piston interconnection schemes at various points in operation.

The engine consists of a two-stage cylinder with a large diameter in the lower part 1 and with a smaller diameter in the upper part 1, provided with windows 11 in the place entering the inside of cylinder G. Both parts of the cylinder are equipped with pistons 2 and 2 of corresponding diameters, with the rod 3 piston 2 passes inside piston rod 3.

The piston 2 of smaller diameter, with its lower position in the cylinder, enters into its part with the windows 11, at which the space above the piston 2 then communicates with the gap between the two pistons. A larger diameter piston 2 is provided around the circumference with an annular recess into which the lower part of the upper cylinder step enters at the upper position of the piston 2. The pistons 2 and 2 act on the cranks located at a right angle to each other.

When the engine is operating by internal combustion, then the lower stage of the cylinder serves as a pump that supplies air or a combustible mixture to tank 7, and the upper stage serves as a combustion chamber of the mixture. When operating as a steam engine, both cylinder tiers work with fresh steam.

In the event of an engine overload during internal combustion, the combustible mixture is injected into the space between the pistons from tank 7 through valve 13.

FIG. 1-4 so far: different engine moments during its operation by internal combustion, namely: when the small piston 2 is at the top dead center, the intake valve (i is open for filling with fresh mixture (or air) from the tank 1. Large piston 2, lifting, throws out the exhaust gases through the valve 8 and sucks the sweet mixture or air through the valve 9.

FIG. 2. By the time of the flash piston 2 passes halfway. Both of its valves 6, 10 are closed, and the piston 2 enters the upper half of the cylinder, receiving in its annular recess protruding walls of the upper stage

cylinder and throwing out the remnants of burnt gases through the valve 8.

FIG. 3. The small piston moves lower dead center, enters the lower chamber, opening windows 11 or openings in protruding walls through which gas enters between the lower side of the small piston and the upper large one. The distance between the pistons increases, first in view of the more rapid lowering of the piston 2, and then because both pistons are directed in different directions. The exhaust valve 10 opens and releases the piston 2 from the pressure of gases that are not transferred from the upper to the lower chamber of the cylinder.

FIG. 4. The piston 2, under the pressure of gases from below, moves upwards, and the piston 2 approaches the bottom dead center, compressing and withdrawing the mixture (or air) to the tank 7 through the valve 12.

If the engine is steam, then through valve 9 fresh steam (low pressure) flows.

The subject of the patent.

1. Engine running steam or internal. burning, characterized by the use of a two-stage cylinder with a large diameter in the lower part 1 and with a smaller diameter in the upper part 1, which has windows or slots 11 in the part entering the larger diameter cylinder 1, which parts of the cylinder are provided with two respectively acting on the the right angle of the cranks, pistons 2, 2, of which the piston 2 has a smaller diameter, when in its lower position in the cylinder, enters into its part with windows 11, through which the space above the piston 2 is then connected with the space between with pistons, the piston 2 of larger diameter is provided at the periphery with an annular recess into which, at its upper position, the lower part of the cylinder wall of a small diameter enters, in which device, during engine operation, internal combustion, the lower part of the cylinder serves as a pump supplying air or The combustible mixture in the tank 7, in the upper part of the cylinder, in this case, the mixture burns, and when the engine is running, both the upper and lower parts of the cylinder are operated with fresh steam.

2. Modification of the engine described in paragraph 1, characterized by the use of valve 13, through which, when the engine is operating by internal combustion, in case of overload, the fuel mixture from the tank 7 is injected into the space between the pistons.
