Description
Es sind bereits gemischverdichtende Zweitaktvergasermaschinen bekannt, bei welchen der Brennstoff vermittels des Unterdrücks im Kurbelgehäuse durch eine Düse in den Über-Strömkanal befördert wird und in diesem eine Einrichtung zur Gemischdurchwirbelung des Brennstoffes mit der Mischluft vorgesehen ist.There are already known mixture-compressing two-stroke carburetor machines in which the fuel by means of the negative pressure in the crankcase through a nozzle into the overflow channel is conveyed and in this a device is provided for mixing the fuel with the mixed air is.
Weiter bekannt sind Saugspritzvergaser, bei welchen Propeller im Mischraurd angeordnet
sind, die durch die Luft betrieben werden und bei dieser Gelegenheit den vorbeistreichenden
Brennstoff zerschlagen, oder bei denen der Propeller mit einer Schleuder verbunden ist, die den Brennstoff durch
deren rotierende Bewegungen zerschleudert. Die Neuerung besteht darin, daß in dem
Überströmkanal bei Zweitaktvergasermaschinen ein Schleuderrad mit Propeller angeordnet
ist, wobei die Schleifderradachse in der Mittellinie des Überströmkanals läuft.. " """
Ein Ausführungsbeispiel ist auf der Zeichnung dargestellt, und zwar zeigt
Abb. ι die Gesamtanordnung,
Abb. 2 einen Querschnitt durch das Schleuderrad im Aufriß,Also known are suction spray carburetors in which propellers are arranged in the mixing chamber, which are operated by the air and on this occasion smash the fuel passing by, or in which the propeller is connected to a sling that flings the fuel through its rotating movements. The innovation is that a centrifugal wheel with propeller is arranged in the overflow channel in two-stroke carburetor machines, the grinding wheel axis running in the center line of the overflow channel
Fig. Ι the overall arrangement,
Fig. 2 is a cross-section through the centrifugal wheel in elevation,

Der durch den Unterdruck in den Über-Strömkanal geförderte Brennstoff läuft von dem Schwimmbehälter g durch Leitung ζ über ein Rückschlagventil und ein Röhrchen auf den Schleuderradteller a. Wenn das Überströmen der komprimierten Luft durch den Überströmkanal bei bx und bz erfolgt, so trifft die Luft die Propeller s und setzt diese in rotierende Bewegung, wobei die mit dem Propeller verbundene Schleuder c mitgetrieben wird. Bei diesem Vorgang wird der Brennstoff aus dem Teller ο durch die Schaufelkanäle d herausgeschleudert, nachdem er sich vorher auf dem Teller verteilt hat, um in feinste Nebelteilchen abgeschleudert zu werden. Die feinsten Nebelteilchen werden dann von der durchstreifenden Luft mitgerissen, 4-5 wogegen die größeren Nebel teilchen und Tröpfchen bis an die trichterförmige- Siebtrommet b prallen und bei der rotierenden Bewegung derselben an der Luft vollständig zerrieben und von dieser ebenfalls mitgeführt werden.The fuel conveyed into the overflow channel by the negative pressure runs from the floating container g through line ζ via a check valve and a tube onto the centrifugal wheel plate a. When the compressed air flows over through the overflow duct at b x and b z , the air hits the propeller s and sets it in a rotating motion, with the spinner c connected to the propeller being driven along with it. During this process, the fuel is thrown out of the plate ο through the shovel ducts d after it has previously been distributed on the plate in order to be thrown off into the finest mist particles. The finest mist particles are then entrained by the roaming air, 4-5 whereas particles and droplets are up to the trichterförmige- Siebtrommet b bounce and the rotating movement thereof completely crushed in the air and also carried by the larger this mist.
