Abstract

Die Erfindung betrifft einen Schalldämpfereinsatz (18, 28) aus einem Formelement zum Einbringen in einen Ringraum zwischen einem Auspuffrohr (20) und einem Auspufftopf (10) mit einem in ein zumindest zeitweise formbeständigen Hüllenelement (36) eingebrachten Gemenge aus Glasfasergarn.The invention relates to a silencer insert (18, 28) made from a molded element for introduction into an annular space between an exhaust pipe (20) and a Muffler (10) with an at least temporarily stable in shape Shell element (36) introduced mixture of glass fiber yarn.

Der Erfindung liegt die Aufgabe zugrunde, einen gattungsgemäßen Schalldämpfereinsatz zu schaffen, der einem hohen thermischen Leistungseintrag standhält.The invention has for its object a generic Muffler insert to create a high thermal power input withstand.

Es wird vorgeschlagen, daß wenigstens ein Teilbereich des Schalldämpfereinsatzes (18, 28) mit einem Kühlmedium (24) beaufschlagbar ist.
