KAISERLICHESIMPERIAL PATENTAMT.PATENT OFFICE. Der Gegenstand der Erfindung betrifft einen Zerstäuber, bei welchem der Brennstoff . durch einen Luftstrom gegen eine einstellbare Düse geschleudert und darauf von der durch den Kolben der Maschine angesaugten Luft durch vor- oder übereinander angeordnete Trichter geführt wird.The object of the invention relates to an atomizer in which the fuel . thrown by a stream of air against an adjustable nozzle and then by the Air sucked in by the piston of the machine is arranged in front of or on top of one another Funnel is guided. Der Zerstäuber ist in Fig. ι im Längsschnitt veranschaulicht.The atomizer is illustrated in Fig. Ι in a longitudinal section. ίο Die Fig. 2 und 3 stellen eine Ausführungsform des Zerstäubers im Längs- und .Querschnitt dar.ίο Figs. 2 and 3 represent an embodiment of the atomizer in longitudinal and .Cross section represent. Das Brennstoffventil α ist von einem Rohr b umgeben, welches in der Nähe des Ventilkegels in einer Düse c endet und somit eine Austrittsöffnung von ringförmigem Querschnitt bildet. d sind Trichter mit kreisförmigem oder eckigem Querschnitt, welche in- und voreinander angeordnet werden können, e e sind Öffnungen, welche vom Innenraum des Zerstäubers ins Freie führen.The fuel valve α is surrounded by a tube b which ends in the vicinity of the valve cone in a nozzle c and thus forms an outlet opening with an annular cross section. d are funnels with a circular or angular cross-section, which can be arranged inside and in front of one another, ee are openings which lead from the interior of the atomizer to the outside. Wird das Brennstoffventil α geöffnet, so wird gleichzeitig durch das Rohr b ein kräftiger Luftstrom gedrückt, welcher den austretenden Brennstoff zunächst gegen die konische Wandung der Düse c drückt.If the fuel valve α is opened, a powerful air flow is simultaneously pressed through the pipe b , which initially presses the emerging fuel against the conical wall of the nozzle c. Beim Austreten aus der Düse c wird der zerstäubte Brennstoff von der durch die Öffnungen e e eintretenden Frischluft aufgenommen. When exiting the nozzle c, the atomized fuel is taken up by the fresh air entering through the openings ee. Um die Zerstäubung des Brennstoffes und die Mischung mit der Luft wirksamer zu gestalten, sind vor oder über der Düse c Trichter rf angebracht. In Fig. 1 sind solche vor demselben angebracht (s. d). In order to make the atomization of the fuel and the mixing with the air more effective, funnels rf are attached in front of or above the nozzle c. In Fig. 1, those are attached in front of the same (see d). In Fig. 2 und 3 ist die Trichterdüse c aus mehreren federnden Lamellen gebildet, welche mit ihren Kanten über- bezw. untereinander liegen.In Fig. 2 and 3, the funnel nozzle c is formed from a plurality of resilient lamellae, which over- BEZW with their edges. lie one below the other. Sobald der Ring f verschoben wird, verkleinert oder vergrößert sich die Düsenöffnung, je nachdem man den Ring in der einen oder anderen Richtung verschiebt.As soon as the ring f is displaced, the nozzle opening is reduced or enlarged, depending on whether the ring is displaced in one direction or the other. Pat en ϊ-Αν Sprüche:Pat en ϊ-Αν Proverbs: ι. Zerstäuber für Explosionskraftmaschinen, dadurch gekennzeichnet, daß der Brennstoff zunächst durch einen Luftstrom gegen eine Austrittsdüse c geschleudert wird und darauf von der durch den Kolben der Maschine angesaugten- 5< Luft durch konische vor- oder übereinander angeordnete Trichter d geleitet wird.ι. Atomizer for explosion engines, characterized in that the fuel is initially thrown by an air stream against an outlet nozzle c and is then guided by the air sucked in by the piston of the machine through conical funnels d arranged in front of or on top of one another. 2. Ein Zerstäuber nach Anspruch 1,' dadurch ■ gekennzeichnet, daß die Durchgangsöffnung der Düse c vergrößert oder 5ί verkleinert werden kann.2. An atomizer according to claim 1, 'characterized ■ that the through opening of the nozzle c is enlarged or 5ί can be reduced. Hierzu 1 Blatt Zeichnungen.1 sheet of drawings.
