^{The piston -B 1} arranged in the cylinder B in the usual way has on its lower edge B * resilient oil shells B ^s , the lower free ends of which come from the oil container B ^s arranged in a ring around the lower open end of the cylinder B in the lowest position of the piston Take up B ¹ OeI and distribute it on the inside of the cylinder B (see Fig. 2).

In the embodiment shown, the movement of piston B ¹ is transmitted to flywheel shaft F ¹ by piston rod C, balancer D, connecting rod E and crank F (see FIG. 2).

The supply of the serving for the operations of the engine gas air mixture occurs through the in Fig. 4 shown in the left longitudinal section G mixing valve, while the discharge of explosion gases occurs through the position shown in Fig. 4 right side sectional Auslafsventil H.

The mode of operation of the mixing valve G is as follows:

If the valve disk G ⁷ is lifted from the valve seat G ¹ by the valve spindle G ⁵ , gas from the gas chamber G ³ passes through the inclined channels G ² to the surface of the valve seat.

At the same time, air also enters through hole G ⁴ and thereby mixes very vigorously with the gas that is well distributed on the valve seat.

This gas mixture passes through the line / after the cylinder B. The exhaust valve H is of known construction and is formed by the valve seat H 'and the valve disk if ² . The movement is given to the exhaust valve H by the valve rod H ³ guided in the bore H ⁱ .

The ignition device, which in the accompanying drawing Fig. 4 between the mixing respectively. Inlet valve G and the exhaust valve H is arranged, consists of the valve housing J \ in which the valve cone J ^{8 is} arranged. The valve cone J ⁶ is carried by the valve spindle J ³ , which is passed through the bore J ⁴ , the lower end of which is sealed ^{by the stuffing box J 5.}

Two or more bores J ⁸ connect a space below the valve seat with the channel J. Above the valve cone J ⁶ is a room J ^7, which occurs when raised poppet J ⁶ with the space below the latter in communication, in which the holes / ⁸ open.

The pipe K ¹ , the bore of which communicates ^{with the space J 7, is} placed on the upper end of the valve housing J ^1. At the top, the tube K ^{1 is expanded} to form a hollow sphere K ² , which has an opening ' K ^B.

The tube K ¹ is surrounded by the forge K over almost its entire length. In the lower part of the same a Bunsen burner (K ⁵ , see Fig. 8) is arranged, which draws its gas from the line K ¹⁰ and the air necessary for combustion through the openings which can be opened or closed more or less by screw K ¹ K ^s (see Fig. 8) is obtained.

This Bun sen burner heats the lower end of the tube K ¹ to a red glow and thereby causes the immediate ignition of the gas entering the bore of the tube K ^1.

The narrowing of the forge K, above the burner K ⁵ , through poor heat conductors K ^u, generates a uniform heat in the lower part of the forge i <T ⁴ , whereby the lower end of the tube K ^{1 is kept} in a uniform red glow . Furthermore, the poor heat conductor K ^u protects the forge K from burning. *

The ignition device works as follows:

As soon as the valve cone J ^{6 is} lifted, gas emerges from the space / through the bores / ⁸ into the space J ⁷ , and from there passes into the bore of the tube K \ is ignited in this and thereby leads to the ignition of the gas mixture in the Room I and thus also in cylinder B.

The residual in the ignition in the space J ¹ and in the cavity of the tube K ¹ Combustion Product, upon the entry of new gas into the space J ¹ and in the ignition tube K ¹ from this through the opening K ³ in the top at the end of the Tube K 'attached ball K ² driven out.

The movement of the various valves GJ and H is, as already mentioned, caused by the valve rods G ⁵ J ³ H ^% . The valves are always pressed onto their respective seat by the action of the springs N, which act on the adjustable nuts of the valve spindles.

Lifting the valve spindles and thus the lifting of the valves from their seats is done by the person sitting on the shaft P Curve wheels R and T through the medium of with rollers G ^and J ⁸ and H ^s provided Aufheber G ¹⁹ J * and H. receives the shaft P from the main shaft F of the motor through gears WW ¹ W ² their drive (see Fig. i).

In order to regulate the evenness of the machine's gait, the gas supply is influenced by a regulator V ; When the machine is moving too quickly, this regulator acts on the valve spindle G ^{5 by} means of the lever V ¹ F ² V ^{s in} such a way that the latter is temporarily ^{not actuated by its lifter G 13} (see FIGS. 1 and 3). For this purpose, the spindle G ⁵ goes through a corresponding laterally extended slot in the guides S ¹ S ² , so that if the balls of the regulator are deflected too far, the lower end G ^{12 of} the spindle G ^{5 is} shifted sideways to such an extent that the lifter G ¹³ does not actuate the spindle G ⁵ during its movement and gas and air are not fed into the cylinder, so an explosion failure must occur. In Fig. 9, the lateral displacement of the lower end G ^{12 of} the spindle G ⁵ to the position of the lifter G ¹³ respectively. a pin fastened on the same, which ^{causes the movement of the spindle G 5} , illustrated in dotted lines.

As soon as the regulator V falls again due to the decreasing speed of the motor, the spindle G ^{5 is} again via the lifter G ¹³ respectively. brought the pin fastened on it, the valve G is actuated, and the cylinder is filled again.

The drive of the regulator F is determined by the shaft ⁴ and the gear W W ^s · effected by the gear W ^'2 of (s. Fig. 1 and 13).

If gasoline is used, it must first be converted into gas. This transformation is carried out by a carburetor which is constructed as follows (see Figs. 5, 6 and 7).

L is a hollow cylinder, the inner space of which is connected to the pipe L ¹ near the bottom; this line is connected at its other end to the space G ¹⁴ under the valve G (see Fig. 4).

When using the gasifier, the gas supply G ¹ G ^{2 is closed} by the tap G ¹⁰ .

Concentrically in the cylinder L there is a narrower tube ZA. The lower end of this tube V- passes through the bottom of the cylinder L, and in this way communicates with the outside air; the flange L ^{3 of} the cylinder base or other suitable means hold the. Tube L in position; the flange L ³ extends a little downwards, embraces the tube L ' ^{2 in} such a way that the upright position of the latter is ensured. The space in the cylinder L has no direct connection with the outside air; the cover of the tube L ² is located below the cover of the cylinder L and is closed by a valve L ⁴ . The valve spindle L ^{5 of} this valve L ⁴ goes through the - extension L ^{6 of} the valve chamber L ¹⁰ ; this extension is screwed into the upper cover of the cylinder L.

The valve spindle L ⁵ abuts against the lower end of the guide L ^{14 of} the valve L ¹ , which is also mounted in the said extension. The valve L ⁷ is seated in the upper end of the extension in the chamber L ¹⁰ .

The entire length of the valve spindle L ⁵ is dimensioned so that the valve L ⁴ rests on the upper end of the tube L ² at the same time as the valve L ^{7 is} on the seat of the extension L.

The circumference of the valve L ⁷ is provided with vertical indentations L ⁸ ; these are connected to vertical depressions ^ ⁹ , which are located in the guide L ^{14 of} the valve L ⁷ . These depressions L ⁸ L ⁹ connect the space L ¹⁰ above the valve L ⁷ with the inner space of the cylinder L.

A suitable gasoline feed L ¹¹ is connected to the space L ¹⁰ above the valve L ⁷ ; the supply of the gasoline through this supply pipe L ¹¹ is regulated by the tap L ¹² . The inner space of the cylinder L is divided into different compartments by partitions JL ¹³ made of fine gauze wire, so that the gasoline is distributed over a large surface and is thereby easily gasified.

The carburetor works as follows: As often as valve G is raised, it is. Gas sucked into cylinder B, and the simultaneous descent of piston B ¹ creates a partial vacuum in tube L ¹ ; as a result, a suction effect is produced in the tube L ^1. The external air in the tube L ² lifts the valve L ⁴ and thus also the valve L ⁷ . The gasoline in the space L ¹⁰ runs through the channels L ⁸ , through the opened valve L ⁷ and through the channels L ⁹ into the cylinder L. The flow of the gasoline through said channels into the cylinder B is accelerated by the suction effect mentioned. The gasoline entering the cylinder L falls on the valve L ⁴ , flows over the beveled edge of the same and is thoroughly mixed with the air which flows in after the cylinder L from the tube L · ² directly below the said edge. This gas and air mixture is transported quickly through the gauze rings L ^1B , where the gasoline and the air combine even more intimately to form a gas mixture. This gas mixture, consisting of air and gasified gasoline, goes into the tube L ¹ and finds its further way through the valve G and the line / to the cylinder B.

If the gas engine is fed by a carburetor, the burner K ^{5 of} the ignition valve is heated with gasoline, which is supplied in a suitable manner.

The machine works as follows: First, gas is ^{let through the supply pipes into space G 4} under valve G and the machine is set in rotation. The cam plate R moves here, like the arrow drawn (Fig. Ι). indicated, from right to left. The working surface R ¹ called disk R lifts the roller G ¹⁴ , the lifter G ¹³ , the spindle G ⁵ and the valve G, whereby fresh gas flows into the line / and to the upper end of the cylinder B. At the same time it descends. the piston B ¹ , and gas stroking through valve G met

the expanding space above piston B ¹ .

When the piston B ^{1 has reached} the lowest point of its stroke, the surface R ^[of the disk R leaves the roller G ¹⁴ , as a result of which it descends and the valve G closes.

During its upward movement the compresses. Piston B ¹ the gas in the cylinder until it reaches its upper stroke change; here the working 'surface T ^{1 of} the disc T reaches the roller / ⁸ , lifts it and with it the lifter J ⁴ , the spindle J ³ and the valve ^{disk / 6 of} the ignition valve.

The fresh gas in the line / comes into contact with the red-hot tube K ⁴ , ignites and burns backwards after the line / and cylinder B. In this way, the gas mixture above the piston B ¹ in the cylinder B is instantly heated, lively Combustion takes place and the explosive force of the gases drives the piston downwards.

The ignition valve J closes immediately after the ignition, since the point T ^{1 of} the cam plate T immediately leaves the role J ^s . As the machine moves on and the piston moves up again, the cam R affects the roller H ⁶ , with it lifts the lift H ⁷ and the spindle H ³ , and the exhaust valve H " ¹ is opened in this way.

The working surface R ^{x of} the disk R does not leave the role H ^s until the piston has reached the top of its stroke, and in this way drives all combustion products out of the cylinder B and the line /. The roll H ^s now leaves the work surface 'R ^{1 of} the disk R, this closes the exhaust valve H, the work surface R ¹ immediately lifts the roll G ¹⁴ again, lets gas and fresh air into the line / and the cylinder B, and the operations mentioned are repeated. If air laden with gasoline is supplied to the machine and the previously described carburetor is used, a great saving in gasoline is achieved by the arrangement described, because the machine only draws in as much gasoline as it does. Activity is necessary.

For this purpose the valve L ¹² , which regulates the gasoline feed line, is connected to the regulator of the engine.

The tap L ¹² then regulates the gasoline inflow to the space L ¹⁰ . The pipe I and the upper part of the cylinder B must be kept in a hot state when gasoline is used. If the pipe and the upper part of the cylinder were cold, the gasoline-impregnated air would be condensed under the pressure prevailing here

liquid gasoline can be formed again, which would greatly affect the efficiency of the machine. Only that part of the cylinder traversed by the piston is surrounded by a water shirt Z when gasoline is used. At ς the water is added, at ^ ² drained (see Fig. 2).
