Abstract
Description
Atmosphäre hin bei geschlossener Hauptdrosselklappe wirksam wird.Atmosphere becomes effective when the main throttle valve is closed.
Die Erfindung wird im folgenden anhand eines Ausführungsbeispiels näher erläutert Die Figur zeigt schematisch in einem Längsschnitt die wesentlichen Bauelemente eines Vergasers nach der Erfindung.The invention is based on a Exemplary embodiment explained in more detail The figure shows schematically in a longitudinal section the essentials Components of a carburetor according to the invention.
Im Hauptansaugkanal 1 des Vergasers ist im Bereich der Leerlauf- und Bypaßöffnungen 4 eine Hauptdrosselklappe 2 schwenkbar angeordnet. Die Haupttlrossel klappe 2 weist eine Verdickung 3 im Umfangsbereich auf, die bei geschlossener Hauptdrosselklappe 2 die Bypaßverbindungsöffnungen 4 abdecken. Durch die darunterliegende Leerlaufgemischaustrittsöffnung 4' gelangt noch Kraftstoff aus einem Leerlaufkanal 5 in einer durch eine Leerlauf-Gemischregulierschraube 6 einstellbaren Menge in den Ansaugkanal unterhalb der geschlossenen Drosselklappe. Ein Zwischenflansch 7 weist einen Zusatzluftkanal 8 auf, der über einen Schlitz eine freie Verbindung (9) zum Ansaugkanal hat. Die Kante dieses Schlitzes 9, welche sich im Ansaugkanal befindet, ist etwas gegenüber einer Nase 15 zurückgesetzt. In the main intake duct 1 of the carburetor, in the area of the idle and bypass openings 4, there is a main throttle valve 2 pivoted. The main choke flap 2 has a thickening 3 in the circumferential area, which when the main throttle valve 2 is closed Cover bypass connection openings 4. Through the idle mixture outlet opening 4 'below still gets fuel from an idle channel 5 in an adjustable amount by an idle mixture control screw 6 in the intake duct below the closed throttle. An intermediate flange 7 has an additional air duct 8, which has a slot has a free connection (9) to the intake duct. The edge of this slot 9, which is in the intake duct is located, is set back slightly with respect to a nose 15.
In der Figur ist das an der Vergaserwand im Bereich des Strömungsschattens vorhandene Kondensat 14 punktiert dargestellt. Es wird durch die austretende Zusatzluft zerstäubt, wobei diese Zerstäubung weitgehend im Durchgangsquerschnitt 16 des Zwischenflansches 7 stattfindet.The figure shows the condensate 14 present on the gasifier wall in the area of the flow shadow shown dotted. It is atomized by the escaping additional air, this atomization to a large extent takes place in the passage cross section 16 of the intermediate flange 7.
