Patentiert im Deutschen Reiche vom 2. April 1914 ab.Patented in the German Empire on April 2, 1914.
Bei Vergasern für mit flüssigem Brennstoff betriebene Explosionsmotoren, bei denen die Mischkammer senkrecht und zentrisch über der Vorrats- oder Schwimmerkammer liegt und mit dieser durch ein Tauchrohr verbunden ist, hat man dieses durch den ganzen Vergaser, einschließlich der Drosselklappe, hindurchgeführt, um bei der Schließstellung der Drosselklappe den langsamsten Gang des leer laufenden Motors zu erzielen.In the case of carburetors for liquid fuel-powered explosion engines where the Mixing chamber is vertically and centrally above the storage or float chamber and is connected to this by a dip tube, you have this through the whole carburetor, including the throttle valve, passed through to in the closed position of the throttle valve to achieve the slowest gear of the idling engine.
Nach der vorliegenden Erfindung wird das untere Ende des die Drosselklappe durchdringenden Röhrchens zur Bildung eines Luftzufuhrspaltes am oberen Ende des Tauchkanals benutzt, und der Ansaugekanal wird während des ersten Teiles der Drosselklappenschwenkung, bei welcher das untere Röhrchenende gegen den Tauchkanal verstellt wird, geschlossen gehalten. According to the present invention, the lower end of the throttle valve penetrating Tube is used to create an air supply gap at the top of the immersion channel, and the suction channel is during of the first part of the throttle valve pivot, in which the lower end of the tube against the immersion channel is adjusted, kept closed.
Bis das ^in der Drosselklappe sitzende Röhrchen sein Zusammenspiel mit dem Tauchkanal beendet hat, wird nämlich die Abdichtung zwischen dem Umfange der Drosselklappe und der Ansaugekänalwandung dadurch aufrechterhalten, daß im Umfange der Drosselklappe ein Federring vorgesehen ist. Dieser paßt sich während der Anfangsschwenkung deraDrosselklappe jeder neuen Stellung der letzteren leicht und dichtschließend an, so daß die schwache Saugwirkung des Motors lediglich durch Vermittelung des Drosselklappenröhrchens zur Einwirkung auf den Tauchkanalinhalt zur Wirkung gelangt.Until the tube seated in the throttle valve has ended its interaction with the immersion channel, the seal between the circumference of the throttle valve and the intake duct wall is maintained in that a spring ring is provided around the throttle valve. This adapts itself during the initial pivoting of a throttle of each new position of the latter easily and tightly closing, so that the weak suction effect of the motor passes only through the medium of the throttle tube to act on the plunger channel content to the effect.
Auf der Zeichnung zeigt:The drawing shows:
Fig. ι den Aufriß des Vergasers teils in Ansicht, teils im Schnitt, währendFig. Ι the elevation of the carburetor partly in view, partly in section, while
Fig. 2 den Grundriß des Vergasers darstellt.Fig. 2 shows the plan view of the carburetor.
Der durch das Rohr α der Vorratskammer b zugeführte Brennstoff wird in dieser in bekannter Weise in einer solchen Höhe erhalten, daß er durch den Tauchkanal c aus der Vor ratskammer in die Mischkammer d gelangen kann.The fuel supplied through the tube α of the storage chamber b is obtained in this in a known manner at such a height that it can pass through the immersion channel c from the storage chamber before into the mixing chamber d .
Über dem Tauchkanal c ist in dem den Ansaugekanal e mit dem Vergasergehäuse f verbindenden Einsatzstück g eine Drosselklappe Ji vorgesehen, deren Spindel i mit Hilfe des Stellhebels / geschwenkt werden kann. Die Drosselklappe wird senkrecht zu ihrer Mittelebene von einem Röhrchen k zentrisch durchdrungen, das in der Verlängerung des Tauchkanals c liegt, wenn die Drosselklappenebene senkrecht zur Vergaserachse steht. Im Umfange der Drosselklappe ist ein Federring I angeordnet, welcher der jeweiligen Stellung des Hebels / entsprechend mehr oder minder aus dem Umfang der-Drosselklappe hervortritt. Wird letztere um ihre Spindel * mittels dieses Hebels geschwenkt, so verschiebt sich die untere Mündung m des Röhrchens dementsprechend gegen die obere Mündung des Tauchkanals c. Hierbei bleibt die Drosselung des Ansaugekanals e jedoch anfänglich in vollem Umfange bestehen; weil der Federring I den Ansaugekanal e geschlossen hält. Erst wenn die Röhrchenmündung m nicht mehr mit der Mündung desA throttle valve Ji is provided above the immersion channel c in the insert piece g connecting the intake channel e to the carburetor housing f , the spindle i of which can be pivoted with the aid of the adjusting lever /. The throttle valve is penetrated centrally perpendicular to its center plane by a tube k , which is in the extension of the immersion channel c when the throttle valve plane is perpendicular to the carburetor axis. In the circumference of the throttle valve, a spring ring I is arranged which, depending on the respective position of the lever, protrudes more or less from the circumference of the throttle valve. If the latter is pivoted around its spindle * by means of this lever, the lower mouth m of the tube moves accordingly against the upper mouth of the immersion channel c. In this case, however, the throttling of the intake duct e initially remains in full force; because the spring ring I keeps the suction channel e closed. Only when the tube mouth m no longer with the mouth of the
Tauchkanals c in Verbindung steht, wird bei fortgesetzter Schwenkung der Drosselklappe h
dem Explosionsgemisch der Zugang zum Ansaugekanal β freigelegt.
Die Wirkungsweise ist folgende:Immersion channel c is connected, the access to the intake channel β is exposed to the explosive mixture with continued pivoting of the throttle valve h.
The mode of action is as follows:
Soll der Motor beim Leerlauf seinen
samsten Gang ausführen, so muß der Ansaugekanal e von der Mischkammer d abgesperrt
werden. Dies wird durch den Federring I erzielt, der bei senkrechter Stellung des Röhrchens
k auf dem ganzen Umfange der Drosselklappe die Verbindung zwischen dem Absaugekanal
e und der Mischkammer d unterbricht. Der Brennstoff wird daher vom Motor dem
Tauchkanal c unmittelbar durch das Röhrchen k entnommen. Das zur Herstellung eines sehr
fetten Gases aus der angesaugten Brennstoffmenge benötigte kleine Luftvolumeii tritt aus
der Lufteinlaßkammer η durch die Seitenöffnungen 0 des Tauchkanals c einerseits und
durch den zwischen dem oberen Ende dieses Kanals und dem unteren Ende des Röhrchens k
befindlichen Spalt p anderseits ein, weil wegen des dichten Abschlusses der Drosselklappe die
Saugwirkung des Motors sich auf diese unter keinem Unterdruck stehenden Öffnungen geltend
macht. Der Ansaugekanal e bleibt vermöge des Federringes / von der Mischkammer d
abgeschlossen, bis die Mündung ni des Röhrchens k außer Verbindung mit dem oberen
Ende des Tauchkanals c tritt. Das während dieser Anfangsschwenkung der Drosselklappe
erzielte Explosionsgemisch ist bei der senkrechten Stellung des Röhrchens k natürlich am
fettesten und wird in dem Maße magerer, wie der Neigungswinkel des Röhrchens k zur Vergaserachse
wächst. Diese Eigenart ermöglicht es, daß das Anlaufen des Motors mittels eines sehr fetten Gasgemisches stets sofort erzielt
wird und dann durch Schrägstellung des Röhrchens k so mager gestaltet werden kann, bis
das Explosionsgemisch den Motor in seiner Leerlaufstellung noch eben zu betätigen vermag.
Ein Hinüberregulieren des Motors über seinen Totpunkt, der hier eintritt, wenn der
Tauchkanal c und die Röhrchenmündung m außer Verbindung getreten sind und der Ansaugekanal
& noch verschlossen ist, kann mit Hilfe des Hebels / nach beiden Richtungen
hin stoßfrei ausgeführt und die Freilegung des Ansaugekanals eingeleitet werden. Die Feder I
tritt hierbei von der Innenwandung des Ansaugekanals e zurück, und es entsteht ein mit
der Schwenkung der Drosselklappe Schritt haltender Unterdruck in der Mischkammer d.
Infolge dieses Unterdruckes tritt der Brennstoff zunächst aus den Seitenöffnungen 0 aus
und wird dann durch die aus der ringförmigen Luftzulaßkammer η um den Kegelmantel q
herum in das Ventil r eintretende Luft auf die umliegenden Flächen verteilt und vergast, ■
während das hierdurch gewonnene Explosionsgemisch in bekannter Weise zum Motor gelangt.
Should the engine be at idle
perform the fullest gear, the suction channel e must be shut off from the mixing chamber d. This is achieved by the spring ring I which, when the tube k is in a vertical position, interrupts the connection between the suction channel e and the mixing chamber d over the entire circumference of the throttle valve. The engine therefore takes the fuel from the submerged channel c directly through the tube k . The small air volume required to produce a very rich gas from the amount of fuel sucked in occurs from the air inlet chamber η through the side openings 0 of the immersion channel c on the one hand and through the gap p located between the upper end of this channel and the lower end of the tube k on the other hand, because Because of the tight seal of the throttle valve, the suction effect of the engine is applied to these openings, which are not under negative pressure. The suction channel e remains closed by the spring ring / from the mixing chamber d until the mouth ni of the tube k is out of communication with the upper end of the immersion channel c . The explosive mixture achieved during this initial pivoting of the throttle valve is naturally at its richest when the tube k is in the vertical position and becomes leaner as the angle of inclination of the tube k to the carburetor axis increases. This peculiarity makes it possible that the start of the engine is always achieved immediately by means of a very rich gas mixture and can then be made so lean by inclining the tube k until the explosive mixture is still able to operate the engine in its idle position. A regulation of the motor beyond its dead center, which occurs here when the immersion channel c and the tube mouth m have come out of connection and the intake channel & is still closed, can be carried out smoothly with the aid of the lever / in both directions and the exposure of the intake channel initiated will. The spring I recedes from the inner wall of the intake duct e , and a negative pressure is created in the mixing chamber d that keeps pace with the pivoting of the throttle valve. As a result of this negative pressure, the fuel first emerges from the side openings 0 and is then distributed to the surrounding surfaces and gasified by the air entering the valve r from the annular air inlet chamber η around the cone shell q, while the resulting explosion mixture is in a known manner reaches the engine.
