Description

Schwimmerloser Vergaser mit einem den Brennstoffzufluß steuernden Hauptluftventil. Vergaser, welche ohne Schwimmer arbeiten, sind meistens mit einem Hauptluftventil ver-, sehen, welches den Brennstoffzufluß während der Ansaugperiode des Motors freigibt. Doch haben derartige Vergaser den Nachteil, niemals ein den jeweiligen Drehzahlen des Motors entsprechendes Gasgemisch zu liefern, besonders wenn der Motor ganz langsam oder ohne Belastung leer laufen soll. Um diesen Fehler möglichst zu vermeiden, mußten noch besondere, sogenannte Leerlauf- und Kompensationsdüsen angewendet werden.Floatless carburetor with one that controls the fuel flow Main air valve. Carburetors that work without a float are usually with one Main air valve, see which fuel flow during the intake period of the motor. But such carburetors have the disadvantage, never a to deliver the appropriate gas mixture at the respective engine speeds, especially if the engine is to idle very slowly or without load. To this bug To avoid them as much as possible, special, so-called idle and compensation nozzles had to be used be applied.

Bei vorliegender Erfindung ist es nicht nötig, mehrere Düsen zu verwenden, und zwar wird dies durch folgende Einrichtung erzielt. Der Vergaser besitzt einen Ventilteller a, welcher in bekannter Art den Brennstoffzufluß b abdeckt. Um jedoch im Leerlauf, keine Hilfsdüse zu benötigen, ist der Ventilteller in der Mitte mit einer Führungshülse c versehen. Diese Hülse verschiebt sich auf einem hohlen Bolzen d während des Ansaugens des Motors hin und her und öffnet dabei einen oder mehr Schlitze e, welche im Bolzen d angebracht sind. Die Schlitze e können durch eine Regelschraube f in der Länge zum Teil verkürzt oder verlängert, also geregelt und eingestellt werden. Die Wirkungsweise ist nun folgende Ist der Motor voll belastet, so wird der Ventilkegel durch das Ansaugen aufgerissen, Brennstoff kann bei b austreten und durch die einströmende Luft zerstäubt und verteilt werden; gleichzeitig werden aber auch die Schlitze e durch die Hülse c freigegeben, und es kann Luft durch die Schlitze eintreten. Dies hat bei Vollast so gut wie keine Wirkung. Anders dagegen, wenn der Motor nur halb belastet ist oder leer läuft. In diesem Falle ist das Verbrennungsgemisch in seiner Zusammensetzung empfindlich, und dem kann mit Hilfe der regelbaren-Luftschlitzee Rechnung getragen werden. Mittels der Regelschraube f wird der freie Lufteintritt durch die Schlitze e .vergrößert oder verkleinert. Damit ändert sich der Brennstoffgehalt des Gemisches in der gewünschten Weise. Jede Verstellung der Schraube f wirkt auch auf den Ventilhub ein.In the present invention, it is not necessary to use multiple nozzles, and this is achieved by the following means. The carburetor has a valve plate a, which covers the fuel supply b in a known manner. However, in order not to need an auxiliary nozzle when idling, the valve disk is provided with a guide sleeve c in the middle. This sleeve moves back and forth on a hollow bolt d while the motor is being sucked in, thereby opening one or more slots e which are made in the bolt d. The length of the slots e can be shortened or lengthened in part by means of a regulating screw f , that is to say regulated and adjusted. The mode of operation is now as follows. If the engine is fully loaded, the valve cone is torn open by the intake, fuel can escape at b and be atomized and distributed by the incoming air; at the same time, however, the slots e are also released through the sleeve c, and air can enter through the slots. This has almost no effect at full load. It is different if the engine is only half loaded or runs idle. In this case, the composition of the combustion mixture is sensitive, and this can be taken into account with the aid of the adjustable louvers. The free air inlet through the slots e is increased or decreased by means of the regulating screw f. This changes the fuel content of the mixture in the desired way. Every adjustment of the screw f also has an effect on the valve lift.
