Description

Vergaser für Zweitaktmotoren. Die Erfindung betrifft einen Vergaser für Zweitaktmotoren und besteht darin, daß eine vom Kurbelkasten aus mit Zerstäubungsluft gespeiste Mischkammer oben mit einem Brennstoffzuführungsventil und unten mit einem in den Arbeitszylinder führenden, selbsttätigen Ventil versehen ist, während zwischen den beiden Ventilen Brennstoffverteilungsnetze angeordnet sind.Carburettor for two-stroke engines. The invention relates to a carburetor for two-stroke engines and consists in that one from the crankcase with atomizing air fed mixing chamber above with a fuel supply valve and below with one in the working cylinder leading, automatic valve is provided, while between the two valves fuel distribution networks are arranged.

Durch die Anordnung gemäß der Erfindung wird eine gleichmäßige Verteilung und Zerstäubung des Brennstoffes erzielt.The arrangement according to the invention results in a uniform distribution and atomization of the fuel is achieved.

Gemäß einer Ausführungsform der Erfindung ist in der Mischkammer ein Brennstofftrichter derart angeordnet, daß er über die Mündung der Zerstäubungsluftleitung hinaus bis an die Verteilungsnetze reicht. Dadurch wird verhütet, daß beim Luftansaugen in den Kurbelkasten Brennstofftröpfchen in die Zerstäubungsluftleitung hineingezogen werden.According to one embodiment of the invention, a is in the mixing chamber Fuel funnel arranged so that it over the mouth of the atomizing air line extends to the distribution networks. This prevents air being sucked in In the crankcase, fuel droplets are drawn into the atomizing air line will.

Auf der Zeichnung ist eine Ausführungsform des Erfindungsgegenstandes in einem achsialen Längsschnitt durch den Vergaser darestellt.The drawing shows an embodiment of the subject matter of the invention shown in an axial longitudinal section through the carburetor.

q. ist die Mischkammer des an den Kopf des Arbeitszylinders i angeschlossenen Vergasers, die unten mit einem in dem Arbeitsraum des Zylinders i !führenden selbsttätigen Ventil 2 und oben mit einem den Brennstoff aus dem .Rohr 6 zuführenden Ventil 5 .versehen ist. 7 ist die Zerstäubungsluftleitung, welche an den Kurbelkasten angeschlossen ist. In der .1Iischkammer .I sind zwischen den beiden Ventilen 2 und $ Verteilungsnetze 3 angeordnet, und über denselben befindet sich ein Trichter ä, der, unmittelbar an das obere Ventil s- anschließend, sich mit seiner Mündung über die Einmündungsstelle des Rohres 7 für die Zerstäubungsluft hinaus bis in die Mitte des oberen Verteilungsnetzes erstreckt.q. is the mixing chamber of the connected to the head of the working cylinder i Carburetor, which below with an automatic leading in the working space of the cylinder i! Valve 2 and at the top with a valve 5 which supplies the fuel from the pipe 6 .is mistaken. 7 is the atomizing air line, which is connected to the crankcase is. In the mixing chamber there are distribution networks between the two valves 2 and 2 3 arranged, and above the same is a funnel ä, the, directly to the upper valve s- then, with its mouth over the confluence point of the pipe 7 for the atomizing air out to the middle of the upper distribution network extends.

Die letztere Anordnung verhütet, daß beim Hochgehen des Arbeitskolbens, also beim Verdichtungshub, bei dem die Zerstäubungsluft in den Kurbelkasten angesaugt und durch den in der Mischkammer 4. entstehenden Unterdruck der Brennstoff über die Leitung 6 und das geöffnete Ventil 5 in den Trichter f; eintritt, Brennstofftröpfchen in die Leitung 7 hineingezogen werden. Das Ventil 2 wird dabei geschlossen gehalten werden. Beim Niedergehen des Arbeitskolbens, also beim Saughub, wird die im Kurbelkasten befindliche Luft verdichtet und gelangt durch die Leitung 7 in die Mischkammer ¢, wo sie sich mit dem Brenn- Stoff vermischt und diesen unter gleichmäßiger Verteilung auf die Netze 3 verstäubt.The latter arrangement prevents that when the working piston goes up, that is, during the compression stroke, during which the atomizing air is sucked into the crankcase and through the negative pressure created in the mixing chamber 4, the fuel is transferred the line 6 and the opened valve 5 into the funnel f; entering, fuel droplets be drawn into the line 7. The valve 2 is kept closed will. When the working piston goes down, i.e. during the suction stroke, the in the crankcase the air located is compressed and passes through the line 7 into the mixing chamber ¢, where they deal with the burning Fabric mixed and this under more evenly Distribution to the nets 3 dusted.
