Description

Der Gegenstand vorliegender Erfindung betrifft eine neue Steuerung von Gaskraftmaschinen für flüssige Brennstoffe, wie Spiritus, Benzin usw., deren wesentliches Merkmal darin zu erblicken ist, daß durch Verbindung des Vergasers, des Einlaßventils und des Auspuffventils in einem einzigen Behälter eine möglichst gedrängte Anordnung erzielt wird.The subject matter of the present invention relates to a new control of gas engines for liquid fuels such as alcohol, gasoline, etc., their essential feature it can be seen that by connecting the carburetor, the inlet valve and the exhaust valve achieved a compact arrangement as possible in a single container will.

Der Vorzug dieser Konstruktion liegt in dem Wegfall langer Rohrleitungen, in der einfachen Unterbringung des Vergasers und in der vollständig selbsttätig sich regelnden Vergasung des Brennstoffes, wobei die Hitze der Abgase, welche unmittelbar nach Austritt aus dem Zylinder den Vergaser bestreichen, zur Beförderung der Vergasung verwendet wird. Die gedrängte Anordnung eignet sich besonders für Motorfahrräder, wobei im Fall eintretender Störungen, welche erfahrungsgemäß hauptsächlich in der Steuerung oder im Vergaser zu suchen sind, durch einfache Herausnahme des einen Ventilkörpers ein rasches Nachsehen der ganzen Vorrichtung ermöglicht wird. Die Gasentwicklung der neuen Anordnung ist eine äußerst vollkommene, außerdem steht dem Motor immer vollständig frisch erzeugtes Gasgemisch zur Verfügung, auch bei größerer Tourenzahl der Motoren, da die Flüssigkeits- und Luftzuführung sichThe advantage of this construction is the elimination of long pipelines in which simple accommodation of the carburetor and in the completely automatically regulating Gasification of the fuel, whereby the heat of the exhaust gases, which immediately after leaving smear the carburetor from the cylinder, used to transport the carburetor will. The compact arrangement is particularly suitable for motorcycles, with in the case occurring malfunctions, which experience shows mainly in the control or are to be looked for in the carburetor by simply removing one of the valve bodies quick viewing of the whole device is made possible. The gas evolution of the The new arrangement is an extremely perfect one, and the engine is always complete Freshly generated gas mixture is available, even when the engines are running at a high number of revolutions, since the fluid and air supply are themselves

selbsttätig entsprechend der Tourenzahl regelt. Aus letzterem Grunde kann auch ein sofortiges Anlaufen des Motors bewirkt werden.regulates automatically according to the number of tours. For the latter reason, an immediate Starting of the motor can be effected.

Der Erfindungsgegenstand, ist in der Zeichnung zur Darstellung gelangt, und zwar zeigt: The subject of the invention is shown in the drawing, namely shows:

Fig. ι einen mit der neuen Anordnung versehenen Zylinder in Seitenansicht, Fig. 2 denselben in Vorderansicht, während Fig. 3 einen Schnitt längs der Zylinderachse der Fig. 2 darstellt.Fig. Ι a cylinder provided with the new arrangement in side view, FIG. 2 the same in front view, while FIG. 3 shows a section along the cylinder axis of the Fig. 2 illustrates.

Wie hieraus ersichtlich, ist mit dem Zylinder α des Motors das Ventilgehäuse b aus einem Stück gegossen, wobei die Innenräume dieser beiden Teile durch den Kanal c miteinander in Verbindung stehen. Innerhalb des Ventilgehäuses b ist ein vertikal verschiebbarer zylindrischer Behälter d angeordnet, dessen als Ventilkegel ausgebildeter oberer Teil unter der Wirkung der außerhalb angeordneten Federn f gegen den Sitz e des Ventilgehäuses b gepreßt wird. Der hierdurch als Auspuffventil ausgebildete Behälter d wird in bekannter Weise zwangläufig mittelbar oder unmittelbar von der Maschinenwelle aus gehoben, z. B. mittels Exzenternockens o. dgl. (in der Zeichnung nicht angegeben). Innerhalb des oberen Teiles des Behälters d ist ein unter Federdruck stehendes Saugventil g vorgesehen, um das Gas- und Luftgemisch in den Zylinder einzuführen, während imAs can be seen from this, the valve housing b is cast in one piece with the cylinder α of the engine, the interiors of these two parts being in communication with one another through the channel c. Inside the valve housing b there is arranged a vertically displaceable cylindrical container d , the upper part of which, designed as a valve cone, is pressed against the seat e of the valve housing b under the action of the springs f arranged outside. The thereby designed as an exhaust valve container d is inevitably lifted indirectly or directly from the machine shaft in a known manner, for. B. by means of eccentric cam o. The like. (Not shown in the drawing). Inside the upper part of the container d , a spring-loaded suction valve g is provided to introduce the gas and air mixture into the cylinder while im

Claims

lower parts a spring-loaded valve tip o, and a valve cone seated on the same spindle h allows the entry of the liquid fuel. One of the known perforated atomizer disks i is attached to the extension of the spindle of the valve cone h. The screw ρ allows you to regulate the fuel supply by hand. At the circumference of the lower part of the

ίο cylinder d there are a number of openings k for sucking in atmospheric air, the size of which can be regulated by a ring pushed over it, also provided with openings / by hand or automatically by the machine. The housing m for the valve cone h is screwed into the cylinder d " and held in place by the fastening flange η ; the latter simultaneously transmits the pressure effect of the springs f to the container d, whereby its upper valve cone is pressed onto the seat e . In the valve housing m the pipe socket t for supplying the liquid fuel is fastened by screwing. Instead of the valve arrangement h o and the atomizer disk i , a pipe communicating with the liquid container can be provided in the cylinder d in a simple manner for introducing the fuel, from the small one

Openings the fuel emerges in an atomized state.

The mode of operation of the new device is as follows: When the cylinder piston moves downwards, the valve g rises as a result of the resulting suction effect, whereby atmospheric air is sucked in through the openings k . The air presses against the light disk i and lifts it, but with it also the valve spindle and the valves h and 0, so that the fuel liquid can enter the interior of the cylinder d. The fuel is entrained by the inflowing air and, as a result of being passed through the openings in the disk i, is atomized and intimately mixed with the air. Complete gasification only occurs when the heat of the exhaust gases passed through the room acts on the mixture of air and fuel. The generated gas enters the cylinder through valve g and channel c. During the subsequent upward movement of the piston, valves g and h close and the gas mixture is compressed. After the ignition has occurred and the piston has again moved downwards, an eccentric cam ¹ lifts the cylinder d so that the used gases through the channel c into space r and from there, after they have contributed to the gasification by heating the walls of the container d , into the exhaust pipe s be discharged.
