Die Erfindung bezweckt die Beseitigung des bei Explosionskraftmaschinen durch die auspuffenden Explosionsgase verursachten Geräusches. The invention aims to eliminate the in explosion engines by the exhausting explosion gases caused noise.

Das Wesen dieses Schalldämpfers, welcher in der Zeichnung in zwei Ausführungsformen veranschaulicht ist, besteht darin, daß die Auspuffgase innerhalb eines bei kleinem Umfang eine große Oberfläche darbietenden undThe essence of this muffler, which in the drawing in two embodiments illustrated is that the exhaust gases within a small amount performing a great surface and

ίο gleichzeitig von außen durch die umgebende Luft beständig gekühlten Wellen- oder Faltenrohres auf einem möglichst langen Wege geführt werden, so daß sie erst nach Verlust ihrer Spannung und entsprechenden Abkühlung ins Freie austreten.ίο simultaneously from the outside through the surrounding Air constantly cooled corrugated or folded tube on the longest possible way so that they only after they have lost their tension and have cooled down accordingly step out into the open.

Die Fig. 1 und 2 stellen Quer- und Längsschnitt einer der beiden Ausführungen dar.FIGS. 1 and 2 show cross and longitudinal sections of one of the two versions.

Das der Länge nach mit Falten oder Wellungen versehene und daher den Gasen einerseits einen großen Raum zu ihrer Ausdehnung, andererseits der außen darüber streichenden Luft eine große Oberfläche darbietende Dämpfungsrohr α umgibt den an die Maschine sich anschließenden Auspuffraum b The longitudinally provided with folds or corrugations and therefore the gases on the one hand a large space for its expansion, on the other hand, the outside air sweeping over a large surface-presenting damping pipe α surrounding the machine to the subsequent exhaust room b

.25 und ein gegen letzteren abgeschlossenes Ableitungsrohr c, welches in das oder die Ausströmrohre d mündet. Sowohl der Auspuffraum b als auch das Ableitungsrohr c stehen durch kleine öffnungen / bezw. g mit dem Innenraum des Dämpfungsrohres a in Verbindung. Um die aus den Löchern f in das Rohr α ausströmenden Gase zu zwingen, die Falten oder Wellungen in ihrer ganzen Ausdehnung zu bestreichen, und den Weg zum Ableitungsrohr c möglichst zu verlängern, wird letzteres mit einem zwischen Auspuffraum b und Rohr d eingeschalteten ?bezw. um das letztere herum angeordneten Mantel oder Zwischenrohr h versehen, welches ebenfalls Löcher i besitzt, die weit ab von den Löchern g des Ableitungsrohres c angeordnet sind. Auf diese Weise werden die Gase gezwungen,. einen langen zickzackförmigen Weg zurückzulegen, ehe sie ins Freie ausströmen. .25 and a discharge pipe c, which is closed off from the latter and opens into the discharge pipe or pipes d. Both the exhaust chamber b and the discharge pipe c are through small openings / respectively. g with the interior of the damping tube a in connection. The f out of the holes in the pipe α effluent gases to force to spread the folds or corrugations in its whole extent, and the way to the discharge pipe c possible to extend the latter is b and a in the exhaust space switched pipe d? BEZW. provided around the latter arranged jacket or intermediate tube h , which also has holes i , which are arranged far from the holes g of the discharge pipe c . In this way the gases are forced. to travel a long zigzag path before they flow out into the open.

Für kleinere Maschinen kann eine Vereinfachung der Vorrichtung in der Weise stattfinden, daß, wie Fig. 3 zeigt, in das Dämpfungsrohr α ein mit seiner Spitze gegen den Aus- ' puffraum b vorragender hohlkonischer Einsatz e eingebaut ist, über dessen Mantelfläche die expandierenden Gase auf ihrem Wege durch das Dämpfungsrohr hinstreichen, während die Höhlung des Einsatzes stets von der äußeren Luft erfüllt ist. Der Austritt der Gase ins Freie kann in diesem Falle durch öffnungen k in der vom Auspuffraum entfernt liegenden Stirnwand des Dämpfungsrohres α erfolgen. For smaller machines, a simplification of the device can take place in such a way that, as FIG. 3 shows, a hollow-conical insert e projecting with its tip towards the exhaust chamber b is built into the damping tube α , over the outer surface of which the expanding gases are installed brush their way through the damping tube, while the cavity of the insert is always filled with the outside air. In this case, the gases can escape into the open through openings k in the end wall of the damping tube α , which is remote from the exhaust chamber.
