Auspuffvorrichtung für Luftfahrzeugmotoren u. dgl. mit Absaugung der Gase. Patentiert im Deutschen Reiche vom 11. Dezember 1924 ab. Exhaust device for aircraft engines and the like with suction of the gases. Patented in the German Empire on December 11, 1924.

Bekanntlich ist von jeher danach gestrebt worden, den Auspuff von Luftfahrzeug- und Automobil- und Motorradmotoren möglichst so anzuordnen, daß die Gase vollkommen und abgekühlt abströmen können.As is well known, the aim has always been to remove the exhaust from aircraft and Automobile and motorcycle engines to be arranged as possible so that the gases perfectly and can flow off cooled.

Z. B. sollte dies durch die Abführung der Gase durch die Tragflächen erreicht werden, wobei das Auspuffgefäß in den Tragflächen angeordnet ist, oder durch einen Auspufftopf mit einer luftdurchspülten Ummantelung zur 10 Kühlung oder durch einen Auspufftopf, der aus zwei meinandergeschobenen Zylindern mit Hohlraum zwischen denselben besteht.E.g. this should be achieved by evacuating the gases through the wings, wherein the exhaust vessel is arranged in the wings, or through a muffler with an air-flushed jacket for cooling or through a muffler, the consists of two cylinders pushed together with a cavity between them.

Alle diese Ausführungen betrafen aber nicht . das Problem der Geräuschlosigkeit bei gleich- 15 zeitig gesteigerter Motorleistung.However, none of these statements concerned. the problem of noiselessness at the same 15 timely increased engine power.

Dagegen will dies die Erfindung tun, wie aus Nachstehendem und den Zeichnungen ersichtlich" ist.On the other hand, this is what the invention wants to do, as can be seen from the following and the drawings " is.

Abb. ι 'stellt den Längsschnitt, Abb. 2 die Draufsicht und Abb. 3 und 4 zwei Querschnitte dar.Fig. Ι 'represents the longitudinal section, Fig. 2 the Plan view and Figs. 3 and 4 show two cross-sections.

Die Abgase des Motors M gelangen durch den Auspuffrohrstutzen E in die Auspuffkammer bzw. werden vom Turboventilator T, der mit hoher Drehzahl läuft, angesaugt, wodurch sie, da sowohl das Auspuffrohrstück wie die Auspuffkammer mit dem darin befindlichen Turboläufer von schallverschlingenden FiIz- und Asbestisolierschichten / umgeben sind, ihren Explosionsschall verlieren und geräuschlos entweichen.The exhaust gases from the engine M pass through the exhaust pipe socket E into the exhaust chamber or are sucked in by the turbo fan T, which runs at high speed. are surrounded, lose their explosion sound and escape noiselessly.

Zugleich bewirkt die sehr kräftige Saugwirkung im Auspuffrohr, daß die explodierten Gase restlos und sehr rasch aus den Zylindem austreten können.At the same time, the very powerful suction in the exhaust pipe causes them to explode Gases can escape from the cylinder completely and very quickly.

Dadurch soll die effektive Motorleistung gesteigert werden.This is intended to increase the effective engine power.

Abb. i.Fig.i.

Uta auch die übrigen; Motorengeräusche noch zu beseitigen, ist der ganze Motorrumpf von Filz- und Asbestschichten / umgeben, also sozusagen schall- und luftdicht abgeschlossen.Uta also the rest; The whole hull of the engine still needs to be removed from the engine Felt and asbestos layers / surround, so to speak, soundproof and airtight.

Die Kühlung des Motors und der Auspuffkammer wird durch Kaltluft bewerkstelligt, wozu kleine Kältemaschinen K benutzt werden und Kaltluftzuleitungen K, Z zu den Zylindern führen und durch kleine Kühlpropeller, deren Antrieb entweder durch Zahnrad oder durch Riemen erfolgt.The cooling of the engine and the exhaust chamber is done by cold air, for which small refrigerating machines K are used and cold air supply lines K, Z lead to the cylinders and by small cooling propellers, which are driven either by gearwheels or by belts.
