Description

Brennstoffverdampfer für Verbrennungsmaschinen mit am Luftansaugrohr befestigter Verdampferkammer Vorrichtungen, durch welche auf Heizkörper auftropfender Brennstoff zum Vergasen gebracht wird, sind bekannt. Es ist auch bekannt, die Verdampferkammern durch Auspuffgase zu erwärmen, um die Verdunstung des Brennstoffes zu beschleunigen und dem Motor warme Luft zuzuführen. Diese bekannten Einrichtungen besitzen den Nachteil, daß der aufgetropfte, verdampfte Brennstoff restlos von der Ansaugluft in den Verbrennungsraum mitgerissen wird, wodurch übersättigte Gasgemische entstehen. Es sind weiterhin auch Brennstoffverdampfer für Verbrennungsmaschinen mit am Luftansaugrohr befestigter Verdampferkammer bekannt, welche eine mittels eines elektrischen Heizwiderstandes erwärmte Platte enthält, durch die auftropfender Brennstoff zum Verdampfen gebracht wird.Fuel evaporator for internal combustion engines with on the air intake pipe attached evaporator chamber devices through which dripping onto radiators Fuel is brought to gasification, are known. It is also known the evaporator chambers to be heated by exhaust gases in order to accelerate the evaporation of the fuel and supply warm air to the engine. These known facilities have the Disadvantage that the dripped, evaporated fuel is completely removed from the intake air is entrained into the combustion chamber, creating supersaturated gas mixtures. There are also fuel evaporators for internal combustion engines on the air intake pipe attached evaporator chamber known, which one by means of an electrical heating resistor Contains heated plate, caused by the dripping fuel to evaporate will.

Von diesen bekannten Einrichtungen unterscheidet sich der Erfindungsgegenstand dadurch, daß die über dem Heizwiderstand liegende Verdampferkammer eine in das Saugrohr mündende enge Düse zum Dampfaustritt aufweist, im übrigen aber vollkommen geschlossen ist, so daß der Brennstoffdampf mit Überdruck in die Saugluft einströmt, und daß weiterhin zwecks Regelung der Brennstoffzuführung ein vertikal in einer Büchse von Hand verschiebbarer Tropfkolben vorgesehen ist, der zwischen Asbestplatten isoliert gelagert und durch einen mit der Brennstoffleitung in Verbindung stehenden federbelasteten Kreuzkopf geschlossen ist.The subject matter of the invention differs from these known devices in that the evaporator chamber located above the heating resistor is one in the suction pipe has opening narrow nozzle to the steam outlet, but otherwise completely closed is, so that the fuel vapor flows into the suction air with excess pressure, and that furthermore, for the purpose of regulating the fuel supply, a vertical in a can of Hand slidable drip flask is provided, which isolates between asbestos sheets stored and by a spring-loaded one connected to the fuel line Cross head is closed.

In der Zeichnung zeigt Fig. i eine Aufsicht auf den Vergaser, Fig. 2 einen Schnitt nach A-A der Fig. i.In the drawing, FIG. 1 shows a plan view of the carburetor, FIG. 2 shows a section along A-A of FIG.

Der Vergaser besteht aus einem Gehäuse i mit angesetztem Luftzuführungsrohr 2 und angegossenem Kasten 3, in dem der Heizwiderstand q. eingebaut ist. An dem Gehäuse befindet sich ein Knierohr 5, durch das die Gase aus der Kammer 6 in den Ansaugstutzen 7 gelangen. 8 ist der oben mit einer Öffnung ausgestattete, den Vergaserraum abschließende Kopf, io ist der im Anschlußstutzen 9 vertikal verschiebbare hohle Tropfkolben, durch dessen Löcher i i der Brennstoff zu dem Tropfstift 12 gelangt. An dem abgesetzten Teile des Kolbens io ist der das Brennstoffrohr tragende Anschlußnippel 13 angeschlossen; 14 ist eine Feder, welche zwischen Nippel und Brennstoffkolben gelagert ist. Der Stutzen 9 ist mit einem Bund ausgestattet, in den die Bolzen 15 eingesetzt werden, die wiederum eine Druckplatte 16 tragen, die als Lager für eine Schraubspindel 17 dient, durch welche der Kolben auf und nieder bewegt wird. Diese Spindel 17 ist mit einer biegsamen Welle 18 gekuppelt, durch welche die Schraubspindel mittels Handrades i9 auf und nieder bewegt wird. 2o ist eine Ersatzdüse; das Benzinrohr 21 führt zum Benzinbehälter 22, und 23 ist die Batterie.The carburetor consists of a housing i with an attached air supply pipe 2 and a cast box 3 in which the heating resistor q. is built in. On the housing there is an elbow pipe 5 through which the gases pass from the chamber 6 into the intake port 7. 8 is the head, which is equipped with an opening at the top and closes off the carburetor chamber, io is the hollow drip piston which is vertically displaceable in the connecting piece 9 and through whose holes ii the fuel reaches the drip pen 12. The connecting nipple 13 carrying the fuel pipe is connected to the remote part of the piston io; 14 is a spring which is mounted between the nipple and the fuel piston. The connector 9 is equipped with a collar into which the bolts 1 5 are inserted, which in turn carry a pressure plate 16 which serves as a bearing for a screw spindle 17 through which the piston is moved up and down. This spindle 17 is coupled to a flexible shaft 18 through which the screw spindle is moved up and down by means of a hand wheel i9. 2o is a replacement nozzle; the gasoline pipe 21 leads to the gasoline tank 22, and 23 is the battery.
