Description

Spritzvergaser. Die vorliegende Erfindung bezieht sich auf den Vergaser nach Patent 352076 und besteht in einer weiteren Ausbildung dieses Vergasers in der Weise, daß außer der Hauptbrennstoffdüse noch eine Zusatzbrennstoffdüse angeordnet ist, die aber erst bei Drosselung der Hauptluftzuführung geöffnet wird, um für die Bergfahrt die erforderliche erhöhte Brennstoffzuführung und damit die nötige größere Leistung des Motors herbeizuführen.Injection carburetor. The present invention relates to the carburetor according to patent 352076 and consists of a further development of this carburetor in in such a way that an additional fuel nozzle is arranged in addition to the main fuel nozzle is, which is only opened when the main air supply is throttled in order for the Ascent the necessary increased fuel supply and thus the necessary larger Bring about power of the engine.

In der Zeichnung ist der Vergaser nach der Erfindung beispielsweise, und zwar schematisch, in drei Arbeitsstellungen dargestellt.In the drawing, the carburetor according to the invention is for example, namely schematically, shown in three working positions.

Abb. i zeigt den Vergaser in Leerlauf-Stellung, Abb. 2 in der Stellung für volle Fahrt in der Ebene und Abb. 3 in Stellung für Fahrt zu Berg.Fig. I shows the carburetor in the idle position, Fig. 2 in the position for full travel on level ground and Fig. 3 in position for travel uphill.

Bei der dargestellten Ausführungsform des Vergasers ist außer der in die Hauptluftdüse 2 mündenden, mit dem Brennstoffbehälter g in Verbindung stehenden Brennstoffdüse =o noch eine ebenfalls mit dem Brennstoffbehälter g verbundene Zusatzbrennstoffdüse 16 angeordnet. Diese Düse ist für gewöhnlich d. h. bei Leerlauf (Abb. i) und bei Vollauf für Fahrt in der Ebene (Abb. 2) geschlossen, so daß in diesen beiden Stellungen die Brennstoffzuführung nur durch die Hauptbrennstoffdüse =o erfolgt. Bei Umstellung des Vergasers auf Fahrt zu Berg (Abb.3) wird durch die in dem Gehäuse i drehbar angeordneten Klappen 3 und q. eine Drosselung der Hauptluftzuführung herbeigeführt und gleichzeitig die Zusatzbrennstoffdüse 16 zwangläufig geöffnet. Diese zwangläufige Öffnung erfolgt bei der dargestellten Ausführungsform des Vergasers durch die obere Klappe (Abb. 3). Infolge Öffnung der Düse 16 wird die Brennstoffzufuhr in den Vergaser erhöht, so daß das Gasgemisch ein reicheres wird und eine für die Bergfahrt nötige größere Leistung des Motors erzielt wird.In the illustrated embodiment of the carburetor is also the opening into the main air nozzle 2 and communicating with the fuel tank g Fuel nozzle = o another additional fuel nozzle also connected to the fuel tank g 16 arranged. This nozzle is usually d. H. at idle (Fig. i) and at Fully closed for driving on level ground (Fig. 2), so that in these two positions the fuel is only supplied through the main fuel nozzle = o. When changing The carburetor on the way to the mountain (Fig.3) is rotatable through the in the housing i arranged flaps 3 and q. brought about a throttling of the main air supply and at the same time the auxiliary fuel nozzle 16 is forced to open. This inevitable In the embodiment of the carburetor shown, the opening takes place through the upper one Flap (Fig. 3). As a result of the opening of the nozzle 16, the fuel is fed into the carburetor increased, so that the gas mixture becomes a richer one and one necessary for the ascent greater engine power is achieved.
