Description

Spritzvergaser. Es sind Vergaser mit stufenweiser Gemischbildung bekannt, die zur besseren Gemischbildung mit einem achsial in der Luftdüse verschiebbaren hohlen Drosselkörper versehen sind; der das Vorgemisch zuführt und dieses sowie die Zusatzluft und das Hauptgemisch regelt, wobei der äußere Rand der ringförmigen Vorgemischauslaßöffnung gleichzeitig die Steuerkante für die Zusatzluft bildet.Injection carburetor. There are known carburetors with a gradual mixture formation, which can be moved axially in the air nozzle for better mixture formation hollow throttle bodies are provided; who supplies the premix and this as well the additional air and the main mixture regulates, the outer edge of the ring-shaped Premix outlet opening at the same time forms the control edge for the additional air.

Die Erfindung besteht in einer in den An- Sprüchen gekennzeichneten besonderen Ausführungsform eines Vergasers der bekannten Art.The invention consists in a Sayings marked special embodiment of a carburetor of the known type.

Der Vergaser ist in Abb. i im Schnitt dargestellt.The carburetor is shown in section in Fig. I.

Von Kanal i kommt ein Vorgemisch, das in einem seitlich liegenden Düsensystem gebildet wird. Nachdem diesem Gemisch durch Öffnung 3 weitere Luft zugesetzt ist, kommt es durch Öffnung 2 in den Hohlraum ¢ des Drosselorgans 5 und gelangt durch die ringförmige Öffnung 7 in den Zerstäubungstrichter 8, in welchem es mit der vorbeiströmenden Ansaugluft vermischt wird.A premix comes from channel i, which is in a side lying Nozzle system is formed. After this mixture was added further air through opening 3 is, it comes through opening 2 into the cavity ¢ of the throttle member 5 and arrives through the annular opening 7 into the atomizing funnel 8, in which it is with the intake air flowing past is mixed.

Durch achsiale Bewegung des Drosselorgans 5 wird die VorgemischdurchgangsöffnUng 2 sowie die Luftdurchgangsöffnung im Zerstäubungstrichter 8 gleichzeitig eingestellt und damit die Gemischmenge reguliert.Axial movement of the throttle member 5 opens the premix passage opening 2 and the air passage opening in the atomizing funnel 8 are set at the same time and thus regulates the amount of mixture.

Durch Verdrehen des Drosselorgans 5 werden nun die Durchgangsöffnungen 6 bzw. 3 für die Zusatzluft des Vorgemisches sowie die Durchgangsöffnung 2 für das Vorgemisch verändert und damit die Gemischzusammensetzung eingestellt.By turning the throttle member 5, the passage openings are now 6 or 3 for the additional air of the premix and the passage opening 2 for the Modified premix and thus adjusted the mixture composition.

ES wüd somit die Gemischmenge durch achsiale und die Gemischzusammensetzung durch radiale Bewegung des Drosselorgans eingestellt.It would thus determine the amount of mixture through the axial and the mixture composition adjusted by radial movement of the throttle member.

Die Vorgernischö$nung 2 kann durch entsprechendes Verdrehen des Drosselorgans ganz abgeschlossen werden, so daß dann bei allen achsialen Einstellungen der Drossel nur Luft angesaugt wird.The Vorgernischö $ nung 2 can by rotating the throttle device accordingly be completely completed, so that then with all axial settings of the throttle only air is sucked in.

,Das stets an der engsten Luftdrosselstelle in -dünner, schirmartig ausgebreiteter Form austretende Vorgemisch wird von der vorbeiströmenden Luft vollends fein vernebelt und gleichmäßig auf diese verteilt. Es kann sich auf diese Weise auch bei Verwendung schwieriger zu zerstäubender Brennstoffe bei den niedrigen Drehzahlen des Motors noch ein gutes .Gemisch bilden, während bei ganz geöffneter Drossel der Zerstäubungsquerschnitt für die Höchstleistung genügend groß bemessen sein kann., That always at the narrowest air throttle point in -thin, umbrella-like The premix that emerges from the expanded form is completed by the air flowing past finely atomized and evenly distributed over them. It can be that way even when using fuels that are difficult to atomize at the low speeds of the engine still form a good mixture, while with the throttle fully open the Atomization cross-section can be dimensioned sufficiently large for maximum performance.

Wie in Abb.2 dargestellt ist, kann ein zweites Schwimmergehäuse für leichten Brennstoff angeschlossen werden. Der Vergaser kann dann durch Verdrehen des Drosselorgans mit dem einen oder anderen Brennstoff oder auch mit beiden zusammen gespeist werden. Beide Vorgemischöffnungen können auch ganz abgedeckt werden.As shown in Figure 2, a second float housing can be used for light fuel can be connected. The carburetor can then be twisted of the throttle element with one or the other fuel or with both together be fed. Both premix openings can also be completely covered.

PATENTANSPRÜCHE: i. Spritzvergaser mit einem achsial in der Luftdüse verschiebbaren hohlen Drosselkörper, der das Vorgemisch zuführt und dieses sowie die Zusatzluft und das Hauptgemisch regelt, wobei der äußere Rand der ringförmigen Vorgemischauslaßöffnung gleichzeitig die Steuerkante für die Zusatzluft bildet, dadurch gekennzeichnet, daß das in einem seitlich liegenden Düsensystem gebildete Vorgemisch und eine erste Zusatzluftmenge durch besondere Öffnungen seitlich in den verschiebbaren Drosselkörper (5) eingeführt. werden, der außerdem drehbar ist, so daZ in an sich bekannter Weise die Gemischmenge durch die eine und die Gemischzusammensetzung durch andere Verstellung geregelt werden kann. PATENT CLAIMS: i. Spray carburetor with an axially in the air nozzle displaceable hollow throttle body, which feeds the premix and this as well the additional air and the main mixture regulates, the outer edge of the ring-shaped The premix outlet opening forms the control edge for the additional air at the same time, characterized in that the formed in a laterally lying nozzle system Premix and a first amount of additional air through special openings in the side introduced the sliding throttle body (5). which is also rotatable, so that, in a manner known per se, the amount of the mixture is determined by the one and the mixture composition can be regulated by other adjustment. 2. Spritzvergaser nach Anspruch i mit Umschaltvorrichtung für zwei verschiedene Brennstoffe, dadurch gekennzeichnet, daß der drehbare Drosselkörper als Umschaltvorrichtung für die Brennstoffe ausgebildet ist. 2. Spray carburetor according to claim i with switching device for two different fuels, characterized in that the rotatable throttle body is designed as a switching device for the fuels.
