PATENT OFFICE.

In Fig. Ι the machine is shown in side view, in Fig. 2 in horizontal section. Fig. 3 Figure 4 shows a cross section and Figure 4 shows the regulator.

A is the water-cooled cylinder, B the piston, which is connected to a flywheel shaft (not shown) by means of the connecting rod. D is a horizontally mounted shaft for operations of the control, which receives its drive by means of conical wheels or the like from the flywheel shaft, they DAF makes one revolution "when the Schwungrädwelle which makes two. On the shaft D sits the chick E of the control cock, the eccentric F and the thumb G.

The jacket of the conical cock E ¹ connects the bore H, which is in communication with the compression chamber I of the cylinder, the bore J, which is connected to the suction of the mixture of air coming from the pipe k and the gas which passes through the Flap L comes over the supply pipe m , the small bore n, Fig. 3, which is in connection with the tube 0, which is closed at the upper end, which is used for ignition and is obtained white-hot by a Bunsen burner b.

The conical plug of the control valve connects the hole JV, which connects the holes H and J of the casing at the time of suction, the small hole a, Fig. 3, which connects the hole η with the hole H at the required moment of ignition, the Hole e which emerges from a cavity made in the plug of the cock, which at the moment of compression and explosion brings the cylinder into communication with a small chamber which is attached to the head of the plug and has the following purpose.

The head of the chick has a narrowed part on which a hood q ^{1 is} pushed, which is closed by a lid d which is screwed into the hood and presses on the edge of a metallic, very elastic disc i. The disk i is fastened to the chick by means of a screw q. The screw q has a hole which communicates with the hole e. The screw iV 'is adjusted so that it forms the counterweight to the hood q ¹ and has the purpose of holding the plug in its jacket without exerting any pressure.

When the compression and inflammation take place, the internal pressure penetrates through the opening a, which leads to the lid d , and drives the hood ^ ¹ outwards, whereby the chick is pushed back into its envelope and thereby ensures a good seal in the most important part Moment.

The screw N ¹ is mounted in a crosshead, which in turn is fastened to the tap with screws. All that is necessary is to unscrew the crosshead in order to pull out the chick for cleaning.

The outlet valve R, Fig. 3, is opened by the lever P at the appropriate moment. The lever P is moved by the thumb G.

It is important with this arrangement that the displaceable chamber of the cock with its metallic membrane directly on the head of the

Claims (1)

Chick is placed so that the chick is arranged horizontally, and that it forms the extension of the shaft D, which is operated directly by the flywheel shaft without transmission. This enables two systems of channels for supply, such as N, for inflammation, such as a, and two holes e for the movable chamber of the chick to be made in a single chick, as well as the corresponding openings in the mantle of the chick. Neither of these systems has any connection with each other. The second system of channels and holes is placed before or after the first and serves to feed a second working cylinder, which is mounted parallel to the first and engages the same flywheel shaft. One must, of course, take care that the canals are at the right angles to one another. The regulator, Fig. 4, consists of the lever T, which rotates around one end V and receives an up and down movement by the eccentric F and the connecting rod U. At the free end of this lever T an angle is attached, one arm of which strikes under an adjusting screw g with every movement, and the other arm of which is provided with a narrow cutting edge h. An elastic steel rail r is firmly connected to the bracket at one end, the other end of which hangs freely and is provided with a small metal weight m , which swings upwards with every movement and hits a set screw f with every downward movement, which controls the oscillations abbreviates. When the machine is moving at the set speed, the rail r acts as a spring and presses the cutting edge h into such a position that, by striking the thumb of the lever /, which rests on the pin of the gas valve L , it straight into the valve opens at the moment of suction. But if the machine goes faster and thus the lever T too, the rail r does not have the time to push back the cutting edge h quickly enough, as a result of which it misses the thumb of the lever /, and the valve remains closed. This continues until the machine has resumed its normal gear. Both the pipe k of the suction air, Fig. 1, and the pipe m of the gas supply line, Fig. 2, are provided with regulating valves in order to be able to set the required gas quantities. The lubricator, Fig. 1, consists of a large cup x, on the bottom of which there is a cock. The chick is set in continuous rotation by the worm wheel and worm. Two slots t are in the chick on opposite sides. These slots allow the oil to fall alternately into a hole q . Due to the rotation of the plug, the bore q ^{opens alternately in front of the openings S 1} , which bring the oil on the one hand to the cylinder and on the other hand to the control. The plug of the lubricator and its upper extension are pierced; At the top, the perforation opens sideways at u, while a screw is inserted at the tip that can close the opening u. The air enters the chick through the mouth u. By enlarging or reducing the opening u one is able to regulate the flow of oil. • Patent claim: A control for gas and similar engines, consisting of a horizontally mounted cock, the plug of which sits on a rotating shaft and is connected to a hood q ¹ in such a way that at the moment of the explosion the cover q ¹ absorbs the overpressure and thereby the plug holds on.
