Description

Vergaser. Es sind Vergaser bekannt, bei welchen zu beiden Seiten eines zylindrischen Schwimmers Luftzerstäuber samt Brennstoffspritzrohreri zur Zerstäubung des Brennstoffes vorgesehen sind, wobei ein gemeinsamer Zuführungskanal das erhaltene Brennstoffluftgemisch der Verwendungsstelle zuführt. Der zylindrische Schwimmer ist aber bei sämtlichen bisher bestehenden Vergasern mit senkrechter Achse im Vergaser angeordnet, so daß er mit seiner Grundfläche an dem unteren Teile des Gehäuses anstößt, wodurch eingedrungenes Wasser in den Zuführungskanal der Spritzdüse abgedrängt wird, was ein sogenanntes Schießen des Vergasers zur Folge hat.Carburetor. There are known carburetors in which one on both sides cylindrical float air atomizer including fuel spray tubes for atomization of the fuel are provided, with a common feed channel obtained Sends fuel-air mixture to the point of use. The cylindrical float but is in all previously existing carburetors with a vertical axis in the carburetor arranged so that he with his base on the lower part of the housing, whereby water that has penetrated into the feed channel of the spray nozzle is pushed away, which has a so-called shooting of the carburetor result.

Außerdem ist das Gehäuse bei den bekannten Vergasern entsprechend dem vertikal eingesetzten Schwimmer in seinem oberen Teile scharfkantig abgesetzt, was auf die Strömung des Luftgasgemisches ungünstig einwirkt. Durch vorliegende Erfindung werden diese Nachteile dadurch behoben, daß der zylindrische Schwimmer horizontal im Schwimmgehäuse derart gelagert ist, daß er in seiner tiefsten Stellung mit zwei Erzeugenden seiner Mantelfläche im Gehäuse aufsitzt, wobei der gemeinsame Zuführungskanal entsprechend der Zylinderfläche des Schwimmers, ohne scharfe Kanten zu bilden, gekrümmt ist.In addition, the housing in the known carburetors is corresponding the upper part of the vertically inserted float is set off with a sharp edge, which has an unfavorable effect on the flow of the air gas mixture. By present Invention, these disadvantages are eliminated in that the cylindrical float is mounted horizontally in the floating housing in such a way that it is in its lowest position with two generators of its lateral surface is seated in the housing, the common Feed channel corresponding to the cylinder surface of the float, without sharp edges to form is curved.

In der Zeichnung ist der Erfindungsgegenstand beispielsweise dargestellt.In the drawing, the subject matter of the invention is shown, for example.

Abb. i zeigt eine Seitenansicht und Abb. 2 eine Vorderansicht des Vergasers, Abb.3 einen Schnitt nach der Linie C-D in Abb. 2 und Abb. 4. einen Schnitt nach der Linie A-B in Abb. i.Fig. I shows a side view and Fig. 2 shows a front view of the Carburetor, Fig.3 a section along the line C-D in Fig. 2 and Fig. 4. a section according to the line A-B in Fig. i.

Das Vergasergehäuse i (vgl. Abb. q.) besitzt in seinem Innern das sogenannte Schwimmergehäuse 2, das in den Brennstoffkanal 3 mündet, der durch den Anschlußnippel d. mit der Zuleitung verbunden ist. Dieser Anschlußnippel d. ist gleichzeitig als Sitz 5 für die Schwimmnadel 6 ausgebildet, welche letztere lose verschiebbar durch den Schwimmer 7 hindurchragt und an ihrem oberen freien Ende mit den in üblicher Weise ausgebildeten Schwimmergewichten 8 in ,Verbindung steht.The inside of the carburetor housing i (see Fig.q.) Has the so-called float housing 2, which opens into the fuel channel 3 through the Connection nipple d. is connected to the supply line. This connection nipple d. is at the same time designed as a seat 5 for the swimming needle 6, which the latter loosely slidably protrudes through the float 7 and at its upper free end with the conventionally designed float weights 8 in connection.

Der Schwimmer 7 besteht aus einem Hohlzvlinder und ist entgegen den bisher bekannten Vergaserkonstruktionen horizontal in dem Schwimmergehäuse 2 im Zentrum gelagert. Die nach vorne zu liegende Stirnwand des Schwimmergehäuses :2 ist mit einer durchsichtigen Glasscheibe g abgeschlossen, so daß der Benzinstand jederzeit ersichtlich ist, wobei aber der Vergaser allseits dicht geschlossen und daher feuersicher ist.The float 7 consists of a Hohlzvlinder and is against the previously known carburetor constructions horizontally in the float housing 2 in the Center stored. The front wall of the float housing, which is to be positioned towards the front: 2 is closed with a transparent pane of glass g, so that the gasoline level can be seen at any time, but the carburetor is tightly closed on all sides and therefore is fireproof.

Zu beiden Seiten des Schwimmergehäuses 2 sind die Luftzerstäuber io angeordnet, die in einen gemeinsamen Saugkanal i i münden, welcher an die zu den :Motoren führenden Zuleitungen angeschlossen ist und eine Drosselklappe 12 besitzt.On both sides of the float housing 2, the air atomizers are io arranged, which open into a common suction channel i i, which is connected to the : Motor leads is connected and has a throttle valve 12.

Der Brennstoffkanal 3 ist mit den Luftdüsen io durch je ein Brennstoffspritzrohr 13 verbunden.The fuel channel 3 is connected to the air nozzles io by a fuel spray tube 13 each.

Am rückwärtigen Teile des Vergasers ist ferner ein Leerlaufzerstäuber 1q. samt Druckfeder 15 und Leerlaufbrennstoffdüse 16 vorhanden.There is also an idle atomizer on the rear of the carburetor 1q. including compression spring 15 and idle fuel nozzle 16 available.

Durch die Düse 5 strömt der Brennstoff in den Kanal 3 und von hier durch die beiderseits des Schwimmers angeordneten Brennstoffdüsen 13 in die Luftzerstäuber io, wobei durch die getrennt voneinander liegenden Saugkammersysteme ein sehr gutes Gasluftgemisch entsteht. Infolge des Zusammenprallens der sich getrennt entwickelnden Gemische in dem gemeinsamen Saugkanal i i werden die einzelnen Benzin- und Luftteilchen miteinander noch besser und inniger vermischt, Zoobei Unreinigkeiten, wie Staub, durch dieses Zusammenstoßen der beiden Gasgemische abgesondert werden, um so mehr als der Saugkanal i i entsprechend gekrümmt und lang ist.The fuel flows through the nozzle 5 into the channel 3 and from here through the fuel nozzles 13 arranged on both sides of the float into the air atomizer io, whereby a very good one due to the separate suction chamber systems Gas-air mixture is created. As a result of the clash of separately evolving Mixtures in the common suction channel i i become the individual gasoline and air particles mixed with each other even better and more intimately, zoo with impurities such as dust, be separated by this collision of the two gas mixtures, all the more so than the suction channel i i is correspondingly curved and long.
