Description

Die Erfindung betrifft eine Drosseleinrichtung für das Brennstoff-Luft-Gemisch für Verbrennungsmotoren, insbesondere Fahrzeugmotoren, die für Schweröl, z. B. Dieselölbetrieb, besonders geeignet ist.The invention relates to a throttle device for the fuel-air mixture for internal combustion engines, especially vehicle engines that are used for heavy fuel oil, e.g. B. Diesel oil operation, is particularly suitable.

Im wesentlichen besteht die Erfindung darin, daß als Drossel ein quer zum Gemischrohr geführter Schieber benutzt ist, der an seiner Drosselkante kammartig ausgebildet ist, vorzugsweise mit einer großen Zahl von zum Teil hintereinanderliegenden Zinken, derart, daß bei mehr oder weniger geöffneter Drossel das Gemisch durch ein Labyrinth von Zähnen streichen muß und dabei immer erneut, und zwar immer wieder in anderer Weise zerteilt wird. So wird der schwer zu vergasende Kraftstoff, welcher schon im Vergaser in feine Tröpfchen zerlegt ist, noch weiter in einen Nebel verwandelt, der dann z. B. durch Erwärmung vollends vergast werden kann.Essentially, the invention consists in the fact that a transverse throttle to the mixture pipe guided slide is used, which is like a comb at its throttle edge is formed, preferably with a large number of partly one behind the other Prongs in such a way that the mixture through a more or less open throttle A labyrinth of teeth has to be painted over and over again, over and over again is divided in another way. So the hard-to-gas fuel becomes which is already broken down into fine droplets in the carburetor, further transformed into a mist, who then z. B. can be completely gasified by heating.

Ein Ausführungsbeispiel ist in der Zeichnung veranschaulicht.An exemplary embodiment is illustrated in the drawing.

Fig. i ist ein Längsschnitt; Fig. 2 zeigt einen Schnitt nach Linie C-D der Fig. i in wesentlich größerem Maßstab.Fig. I is a longitudinal section; Fig. 2 shows a section along the line C-D of Fig. I on a much larger scale.

Die Ansaugluft tritt in Richtung des in Fig. i eingezeichneten Pfeiles in den Lufttrichter c, welcher in neuer, aber in vorliegender Erfindung nicht beanspruchter Weise axial mittels Zapfens f verschiebbar ist gegenüber der Brennstoffspritzdüse b.The intake air occurs in the direction of the arrow shown in FIG in the air funnel c, which is new but not claimed in the present invention Way axially by means of pin f is displaceable relative to the fuel injection nozzle b.

Als Drosselschieber ist ein quer zur Gemischströmung geführter Kolben p gezeichnet, der mittels Winkelhebels q und Zugstange r in seiner zylindrischen Führung o nach Bedarf, z. B. mittels Fußhebels, bewegt werden kann. Besonders neu und eigenartig ist, daß der Zylinderschieber p an seinem unteren Ende mit einer großen Anzahl von seiner Achse parallelen Zähnen u ausgestattet ist, die dann, wenn der Schieber mehr oder weniger geöffnet wird, ein Labyrinth für das durchstreichende Brennstoff-Luft-Gemisch bilden. Diese Zähne u werden zweckmäßig dadurch geschaffen, daß der untere Teil des Schiebers mit sich kreuzenden Systemen paralleler Schlitze t versehen wird, und zwar vorteilhaft so, daß die Kanten dieser Zähne dem Brennstoff-Luft-Gemisch entgegenstehen und es so an jedem der zahlreichen hintereinander versetzt stehenden Zähne immer wieder aufspalten, ablenken und zerteilen.As the throttle slide is a transverse to the mixture flow drawn piston is p, the q by means of the angle lever and pull rod r in its cylindrical guide o required, for example. B. can be moved by means of a foot lever. What is particularly new and peculiar is that the cylinder slide p is equipped at its lower end with a large number of teeth u parallel to its axis, which, when the slide is more or less opened, form a labyrinth for the fuel-air mixture to sweep through . These teeth u are expediently created in that the lower part of the slide is provided with intersecting systems of parallel slots t, advantageously so that the edges of these teeth oppose the fuel-air mixture and so offset it at each of the numerous one behind the other Keep splitting, distracting and dividing standing teeth.

Auf diese Weise wird die Vergasung des Brennstoffs wesentlich verbessert.In this way, the gasification of the fuel is significantly improved.
