Die Erfindung bezweckt, die Entzündung des Gasgemisches im Cylinder mit gröfserer Sicherheit herbeizuführen und infolge dessen an Geschwindigkeit zu gewinnen.The aim of the invention is to ignite the gas mixture in the cylinder with greater safety bring about and gain speed as a result.

Die Einführung des Gases und der Luft in den Cylinder A, sowie die Entzündung der Uebertragungsflamme und der Hauptfüllung regelt der in Fig. 7 einzeln dargestellte Schieber F, ■welcher durch die Wirkung der auf der Hauptwelle D sitzenden Daumenscheibe G auf seiner jStange α abwärts bewegt und nach dem Vorübergang des Daumens b von der Feder c wieder heraufgezogen wird. Letztere ist auf dem Ansatz d des Maschinengestells angebracht, während ein unter Federwirkung stehender Stift e mit seiner schrägen Fläche /, Fig. 3, gegen eine Nase der Stange α drückt und den Hub derselben begrenzt bezw. Stöfse des Schiebers F verhütet. Die Daumenscheibe G sitzt lose auf der Hauptwelle und ist mit einer Nuth 11 versehen, in welche ein in der festgekeilten Muffe 13 befindlicher und unter Federwirkung stehender Stift 12 so eingreift, dafs er bei der Drehung nach rechts die Daumenscheibe mitnimmt, dieselbe jedoch bei Drehung der Welle nach links nicht beeinfiufst.The introduction of the gas and the air in the cylinder A, as well as the inflammation of the Uebertragungsflamme and the main filling regulates the slide individually in Fig. 7 shown F, ■ which α by the action of the seated on the main shaft D thumb wheel G at its jStange moved downward and after the passing of the thumb b is pulled up again by the spring c. The latter is attached to the approach d of the machine frame, while a spring-loaded pin e with its inclined surface /, Fig. 3, presses against a nose of the rod α and limits the stroke of the same respectively. Bumps of the slide F prevented. The thumb disk G sits loosely on the main shaft and is provided with a groove 11, into which a spring-loaded pin 12 located in the wedged sleeve 13 engages so that it takes the thumb disk with it when it is turned to the right, but takes the thumb disk with it when the Wave to the left not affected.

Ein Schieber H, welcher an dem Kreuzkopf h befestigt ist "und durch die Stange g von dem Excenter / auf der Hauptwelle Bewegung erhält, vermittelt den Auspuff, und zwar gelangen die Verbrennungsgase durch den Kanal 16 des Cylinders, die Schieberöffnung 15 und das Loch 14 des Schieberdeckels M ins Freie, Fig. 1 und 3.A slide H, which is attached to the cross head h "and which is moved by the rod g of the eccentric / on the main shaft, provides the exhaust, the combustion gases pass through the duct 16 of the cylinder, the slide opening 15 and the hole 14 the slide cover M into the open, Fig. 1 and 3.

Aufser dem Schieber H ist noch der Kolben k einer Luftpumpe K, sowie der Kolben / einer Gaspumpe L an dem Kreuzkopf h befestigt, so dafs diese ebenfalls von dem Excenter / bewegt werden. Die Gaspumpe L führt Gas nach der Zündkammer i des Schiebers F zur Entzündung der Füllung, während die Luftpumpe K einen Luftstrom auf die Flamme eines in dem Kegel η befindlichen festen Brenners m treibt und dadurch bewirkt, dafs diese Flamme sammt der Luft bei Ankunft des Schiebers F in die Zündkammer i tritt und den Inhalt derselben für die nächstfolgende Entzündung der Cylinderfüllung entzündet.In addition to the slide H , the piston k of an air pump K and the piston / a gas pump L are also attached to the cross head h so that they are also moved by the eccentric /. The gas pump L leads gas to the ignition chamber i of the slide F to ignite the filling, while the air pump K drives a stream of air onto the flame of a fixed burner m located in the cone η and thereby causes this flame to be combined with the air when the slide arrives F enters the ignition chamber i and ignites the contents of the same for the next ignition of the cylinder filling.

Das Gas zur Speisung der Maschine wird gewöhnlich von der Hauptleitung bei ο in eine Kammer p, Fig. 1, 2 und 4, eingeführt. Es strömt dann zum Theil nach dem Schlauch q und von da durch ein Regulirventil r nach dem kleineren Schlauch s, aus welchem es durch Röhren und Kanäle t nach den Oeffhungen u des Schieberdeckels v, Fig. 3 und 6, und schliefslich, wenn diese Oeffhungen frei werden, in den Schieber F, sowie durch w in den Cylinder gelangt. Hier mischt es sich mit der bei entsprechender Stellung des Schiebers durch die Oeffnungen x, Fig. 3, aus der Atmosphäre nach dem Kanal w strömenden Luft.The gas for feeding the machine is usually introduced from the main line at ο into a chamber p, FIGS. 1, 2 and 4. It then flows partly to the hose q and from there through a regulating valve r to the smaller hose s, from which it flows through tubes and channels t to the openings u of the slide cover v, FIGS. 3 and 6, and finally when these openings become free, enters the slide F and w into the cylinder. Here it mixes with the air flowing from the atmosphere to the channel w through the openings x, FIG. 3, when the slide is in the appropriate position.

Ein anderer Theil des Gases geht aus der Kammer p durch die mit einem Hahn ζ, Fig. 2 und 4, versehene Röhre y zum Brenner m, und das übrige Gas wird aus p durch die Röhre 1 von der Pumpe L angesaugt und durch ein Ventil 2 in die Röhre 3 getrieben, welche durch die Röhre 4 mit der Oeffnung 5 verbunden ist, die ihrerseits bei entsprechender Stellung des Schiebers das Gas durch den Kanal z¹ an die Zündkammer i abgiebt. DieAnother part of the gas goes from the chamber p through the tube y provided with a cock ζ, Figs. 2 and 4, to the burner m, and the remaining gas is drawn in from p through the tube 1 by the pump L and through a valve 2 driven into the tube 3, which is connected by the tube 4 to the opening 5, which in turn releases the gas through the channel z ¹ to the ignition chamber i when the slide is in the appropriate position. the

Claims

Tube 4 has a regulating valve 6 and also a valve 7, FIG. 5, through which any excess gas to the chamber / gets back. The air for driving the burner flame into the ignition chamber is sucked in by the pump K through the valve 8 and then pushed through the valve 9 and pipe 10 to the cone η so that it, when the slide F is at its lowest. Position is located with the flame enters the ignition chamber and thus causes the ignition of the gas it contains. N denotes the spaces for water cooling that surround the cylinder and are present in the valve covers. If you now open the main line tap (not visible in the drawing) and the taps ζ and 6, the gas flows into the chamber / and fills the hose q as well as the tubes 1 and y. Then you ignite the flame of the burner m, open the regulating valve r and turn the flywheel in the direction of the arrow, Fig. 2. When the piston k I descends, air enters pump K and gas enters pump L. Also the Main piston B goes down, but only reaches its lowest position when the pump pistons have already completed half of their upward travel, namely the piston / has just passed a groove z3 arranged in the inner wall of its cylinder and connected to the tube 1, so that all the gas upstream of it is forced through valve 2 to tube 3. When the flywheel continues to rotate, the thumb disk G pushes the slide F downwards, so that the ignition chamber i comes into contact with the atmosphere and the opening 5 becomes free. As a result, the ignition chamber fills with gas, which is immediately ignited by the burner flame blown in. Now the openings χ for the air inlet and the openings u for the gas are also open, so that the combustible mixture passes through the slide F and the channel w under the engine piston. If the latter has carried out about a third of its upward gear, the upper end of the slide rod α is free from the thumb b. As a result, the spring c suddenly pulls the slide F upwards, closes all the openings of the slide cover ν and connects the ignition chamber i with the channel w, so that the cylinder filling is ignited. In Fig. 3 the individual parts are drawn in the position corresponding to this effect. The piston B is now driven to its highest position, and then the opening 15 in the slide H is opposite as a result of the movements of the eccentric / exhaust duct 16, so that it faces the opening 14 of the slide cover M and allows the combustion gases to escape. Patent claims: On gas-powered machines in which the combustible mixture of air and gas is not compressed:

1. The use of a pump for driving of gas in the ignition chamber.

2. The use of a pump to drive gas into the ignition chamber in connection with another pump, which sends an air jet into the ignition chamber or whose proximity drives, for the stated purpose.

3. The use of a pump that injects gas into the ignition chamber, as well as an air jet drifts into the same or near them, for the purpose indicated.
