Description

Schalldämpfer für den Auspuff von Brennkraftmaschinen. Die Erfindung betrifft einen Schalldämpfer für den Auspuff von Brennkraftmaschinen. der aus einem mit Einschnitten versehenen, an den Auspuff angeschlossenen inneren Rohr und einem Rohrmantel besteht und bei dern gemäß der Erfindung der zwischen innerem Rohr und Rohrmantel gebildete Ringraum durch auf dem inneren Rohr sitzende Ringscheiben in gegeneinander abgeschlossene Teilkammern unterteilt ist.Silencers for the exhaust of internal combustion engines. The invention relates to a muffler for the exhaust of internal combustion engines. the one from one notched inner pipe connected to the exhaust and a There is pipe jacket and in those according to the invention between the inner pipe and Annular space formed in the pipe jacket by annular disks seated on the inner pipe in mutually closed sub-chambers is divided.

Es ist bereits vorgeschlagen worden, die aus dem Auspuff von Brennkraftmaschinen kommenden Dämpfe und Gase durch einen Schalldämpfer hindurchzuführen, der aus einem inneren, mit Einschnitten versehenen Rohr in einem Rohrmantel besteht. Wegen. der verhältnismäßig großen Ringraumkammer ist die Schalldämpfung bei diesen Vorrichtungen unvollkommen, und ein großer Teil der Verbrennungsgase bleibt im Ringraum stehen, ohne durch das innere Rohr hindurch ausgestoßen zu werden. Diese Nachteile sind gemäß der Erfindung dadurch beseitigt, daß der Ringraum in eine Reihe von Einzelkammern aufgeteilt ist, die einerseits eine bessere Schalldämpfung bewirken und zweitens dazu beitragen,, daß die in die Kammern austretenden Verbrennungsgase leichter in da Ausstoßrohr des Schalldämpfers zurückgeführt werden.It has already been suggested that from the exhaust of internal combustion engines pass coming vapors and gases through a silencer that consists of a inner tube provided with incisions in a tube jacket. Because. the relatively large annulus chamber is the sound attenuation in these devices imperfect, and a large part of the combustion gases remain in the annulus, without being ejected through the inner tube. These disadvantages are eliminated according to the invention in that the annular space in a series of individual chambers is divided, which on the one hand cause better sound absorption and on the other hand help, that the exhaust gases in the chambers in easier because the exhaust pipe of the silencer is returned.

In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes in drei Abbildungen dargestellt. Es zeigen: Abb. i den neuen Auspuffschalldämpfer im Schnitt, Abb. a das innere Rohr in Aufsicht, Abb. 3 eine Ansicht des zusammengesetzten Auspuffschalldämpfers.The drawing shows an exemplary embodiment of the subject matter of the invention shown in three figures. They show: Fig. I the new exhaust silencer in section, Fig. a the inner tube in plan, Fig. 3 a view of the assembled Exhaust silencer.

In einem zwecksAnschlusses an den Auspuff verjüngten Rohrmantel a befindet sich das mit der Verjüngung b übereinstimmende innere Rohr c. Dieses innere Rohr c ist nach beiden Seiten offen, ragt mit einem Ende durch die Verschlußkappeh hindurch und ist mit Einschnittenid versehen. Der zwischen dem Rohrmantel a und dem inneren Rohr c gebildete Ringrauen f ist durch auf dem Rohr c sitzende Ringscheiben e in eine Reihe von gegeneinander abgeschlossenen Einzelkammern unterteilt.In a pipe jacket tapered for connection to the exhaust a the inner tube c, which corresponds to the taper b, is located. This inner Tube c is open on both sides, one end protrudes through the closure cap through and is provided with an incision. The between the pipe jacket a and the inner tube c formed by ring ridge f is by seated on the tube c ring disks e divided into a number of mutually sealed individual chambers.

Die am Eintrittsende des Rohres c angeordnete Ringscheibe dient zum Aufsetzen auf die Verjüngung b, während über das Austrittsende des Rohres c eine Kappe la geschoben wird, die mittels Bajonettverschlusses i auf dem Rohrmantel a befestigt wird.The annular disc arranged at the inlet end of the tube c is used for Put on the taper b, while on the outlet end of the tube c a Cap la is pushed, which by means of bayonet lock i on the pipe jacket a is attached.

Die ausgestoßenen Verbrennungsgase gelangen durch das innere Rohr c ungehemmt ins Freie, während der Schall in den einzelnen Teilkammern gedämpft wird. Zum Auseinandernehmen des . Schalldämpfers zwecks Reinigung bedarf es lediglich der Entfernung der Kappe h. Das mit Ringscheiben e besetzte innere Rohr kann dann aus dem Rohrmantel a entfernt weiden.The exhausted combustion gases pass through the inner tube c uninhibited into the open, while the sound is attenuated in the individual sub-chambers will. To take apart the. All that is required is the silencer for cleaning the removal of the cap h. The inner tube occupied with washers e can then graze away from the pipe jacket a.
