Sclialldämpfer für VerbrennungsmotorenSilencers for internal combustion engines

Die Neuerung "bezieht sich auf einen Schalldämpfer für Verbrennungsmotoren. The innovation "relates to a muffler for internal combustion engines.

Solche Sehalldämpfer "bestehen häufig aus einem doppelwandigen Rohr, dessen Innenmantel düsenartig eingezogen und im Anschluß daran diffusionsartig erweitert ist, wobei zwischen beiden Mänteln, von denen der innere perforiert ist, eine über die Länge des Rohres gleichbleibende dicke Schicht schallabsorbierende Masse eingelagert ist.Such silencers "often consist of a double-walled one Tube, the inner jacket of which is drawn in like a nozzle and then expanded like a diffusion, with between the two jackets, the inner one of which is perforated, one along its length of the pipe a constant thick layer of sound-absorbing compound is embedded.

Der Zusammenbau eines in bekannter Weise derart aufgebauten Schalldämpfers wird erfindungsgemäß erleichtert, wenn der Innenmantel für das Einschieben in den Außenmantel mit vom Düsenende ausgehenden Längsschlitzen versehen ist, wie dies zwecks Gasauslaß bei schallgedämpften, im übrigen aber anders aufgebauten Auspufftopfen bekannt ist.The assembly of a so constructed in a known manner According to the invention, the silencer is facilitated if the inner jacket for insertion into the outer jacket with the nozzle end outgoing longitudinal slots is provided, as is the case for the purpose of gas outlet in the case of soundproofed ones, but otherwise constructed differently Muffler is known.

Der Zusammenbau des Schalldämpfeers der Neuerung wird weiter erleichtert, wenn auch die schallabsorbieraö.e Masse einen längs-The assembly of the silencer of the innovation is further facilitated, even if the schallabsorbieraö.e mass has a longitudinal

The inner and outer tubes are expediently provided with a locking device at the inner end.

Die Zeichnung zeigt beispielsweise schematisch eine Ausführungsform der Neuerung und zwar ist: .. " ' The drawing shows, for example, schematically an embodiment of the innovation, namely: .. "'

Ig. 1 Eine Seit.aaansicht des Schalldämpfers und ig. 2 eine Draufsicht auf das hintere Ende des Sehalldämpfers.Ig. 1 A side view of the muffler and ig. 2 is a plan view of the rear end of the acoustic damper.

Das innere Rohr 2 ist an einem Ende 3 eingezogen und mit Durchlochungen 4 versehen. Beim Zusammenbau des Sehalldämpfers wird es zunächst mit dem gespaltenen Mantel 5 aus schalldämpfendem Material bedeckt. Dieser kann, vermäge des Spaltes 12, leicht über das eingezogene Ende 3 des Rohres 2 geschoben werden. Das Ganze wird dann in das Außenrohr 6 gesteckt, wobei die Schlitze 7 in dem Rohr 2 diese Arbeit erleichtern bzw. erst ermöglichen.The inner tube 2 is drawn in at one end 3 and has perforations 4 provided. When assembling the Sehalldämpfers it first with the split jacket 5 made of sound-absorbing Material covered. This can, due to the gap 12, easily be pushed over the drawn-in end 3 of the tube 2. The whole is then inserted into the outer tube 6, with the slots 7 in the tube 2 facilitate this work or enable it in the first place.

Das freie Ende 8 des Innenrohres 2 stößt schliesslich auf die Einbörde3?lung 9 des Außenrohres 6 und wird dabei leicht gespreizt. Gleichzeitig rastet am anderen Ende das Außenrohr 6 mit einigen Rasten 10 in eine Ringnut 11 des Innenrohres 3 ein.The free end 8 of the inner tube 2 finally meets the Einörde3? Lung 9 of the outer tube 6 and is slightly spread. At the same time, at the other end, the outer tube 6 engages with a few notches 10 in an annular groove 11 of the inner tube 3.
