Description

531 118 2 Figur l visar en ljuddämpare sedd från sidan. 531 118 2 Figure 1 shows a muffler seen from the side.

Figur 2 visar en ljuddämpare i tvärsnitt.Figure 2 shows a muffler in cross section.

Uppfinningen avser en rörformig rund ljuddämpare 1, som kännetecknas av att det inne i röret 2 finns en resonansplåt 3, som omges av det ljudabsorberande materialet 4, och av att resonansplåten 3 inte är fäst vid rörets 2 inre yta.The invention relates to a tubular round muffler 1, which is characterized in that inside the tube 2 there is a resonant plate 3, which is surrounded by the sound-absorbing material 4, and in that the resonant plate 3 is not attached to the inner surface of the tube 2.

Resonansplâten 3 som monteras inne i röret 2 har en tjocklek på 0,4 mm och en bredd som utgör 2/3 av rörets 2 yttre diameter.The resonant plate 3 which is mounted inside the tube 2 has a thickness of 0.4 mm and a width which constitutes 2/3 of the outer diameter of the tube 2.

Resonansplåten 3 och det omgivande ljudabsorberande materialet 4 kan skjutas in i röret 2, varvid långa ljudvågor inte kan passera genom röret 2.The resonant plate 3 and the surrounding sound-absorbing material 4 can be pushed into the tube 2, whereby long sound waves cannot pass through the tube 2.

För att underlätta monteringen, kan en hängskena 5 fästas parallellt med röret 2 vid övre delen av röret 2 som omger ljuddämparen 1.To facilitate assembly, a hanging rail 5 can be attached parallel to the tube 2 at the upper part of the tube 2 which surrounds the muffler 1.

Det är självklart för en fackman att uppfinningens utföringsformer inte begränsas till ovan beskrivna exempel, utan att de kan variera inom ramen för bifogade patentkrav. Sålunda kan man inom ramen för uppfinningen vid behov tillverka ljuddämpare som är mer komplicerade än de som beskrivs i exemplen.It is obvious to a person skilled in the art that the embodiments of the invention are not limited to the examples described above, but that they may vary within the scope of the appended claims. Thus, within the scope of the invention, mufflers which are more complicated than those described in the examples can be manufactured if necessary.
