Description
Schwimmerloser Vergaser. Vorliegende Erfindung betrifft einen schwimmerlosen Vergaser, dessen Brennstoffzufuhr durch eine konische Brennstoffnadel b mit einer halbkugelförmigen Ventilfläche geregelt wird. Der Brennstoff tritt durch das Kaliber a zum Brennstoffventil. Die Brennstoffzerstäubung findet an den Spritzöffnungen c statt. Die Brennstoffnadel b wird durch das Hauptluftventil e, an das ein Schieber m, n für zusätzliche Zerstäubungsluft angebaut ist, verstellt. Die Gemischdrossel besteht aus einem Rohrschieber g, welcher durch seine Drehung auf dem feststehenden Teil f die Gemischzufuhr regelt. Gleichzeitig steuert dieser Drosselschieber den Eintritt zusätzlicher Verbrennungsluft, die durch die Öffnungen h und i im Vergaserrohre bzw. im Schieber g selbst in das Saugrohr gelangt. Die Öffnungen h können durch den Ringschieber k geregelt werden. In dem oberen Teil des Rohrschiebers ist bei l für den Leerlauf eine kleine Öffnung vorgesehen. Ferner ist für den Leerlauf in das Hauptluftventil e ein kleines Luftventilchen d mit geringem Hub eingebaut, das bei seinem Anheben auf die Brennstoffnadel einwirken kann. Die Arbeitsweise ist nun folgende Bei geschlossener Gemischdrossel ist für den Leerlauf noch eine Verbindung zwischen dem Saugrohre und dem Zerstäuberrohre durch die kleine Öffnung l hergestellt. Das große Ventil e, das durch eine starke Feder belastet ist, kann sich wegen der nur schwachen Saugwirkung nicht heben, wohl aber das kleine Luftventil d, dessen Hub im großen Ventil beschränkt ist. Die Spindel des kleinen Luftventils d stößt also auf das Brennstoffventil und öffnet dieses entgegen der Wirkung der schwachen Ventilfeder, so daß eine beschränkte Menge Brennstoff für den Leerlauf freigegeben wird.Floatless carburetor. The present invention relates to a floatless carburetor, the fuel supply of which is regulated by a conical fuel needle b with a hemispherical valve surface. The fuel enters the fuel valve through caliber a. The fuel atomization takes place at the injection openings c. The fuel needle b is adjusted by the main air valve e, to which a slide m, n for additional atomizing air is attached. The mixture throttle consists of a pipe slide g, which regulates the mixture supply by rotating it on the stationary part f. At the same time, this throttle slide controls the entry of additional combustion air, which enters the intake manifold through openings h and i in the carburetor tubes or in slide g itself. The openings h can be regulated by the ring slide k. In the upper part of the pipe valve there is a small opening at l for idling. Furthermore, a small air valve d with a small lift is built into the main air valve e for idling, which can act on the fuel needle when it is raised. The mode of operation is now as follows. When the mixture throttle is closed, a connection between the suction pipe and the atomizer pipe is made through the small opening 1 for idling. The large valve e, which is loaded by a strong spring, cannot lift because of the weak suction effect, but the small air valve d, whose lift is limited in the large valve, can. The spindle of the small air valve d strikes the fuel valve and opens it against the action of the weak valve spring, so that a limited amount of fuel is released for idling.
