Abstract

To sum up, the invention describes a silencer for internal combustion engines, which is surprisingly characterised in that its outer casing is composed of plastic. A silencer which is cost-effective to manufacture is thereby described, which compared to the known silencers is significantly lighter in weight and is not susceptible to corrosion problems, that is its service life is far superior to conventional silencers.

Description

Die Erfindung betrifft Schalldämpfer für Verbrennungsmotoren.The invention relates to silencers for internal combustion engines.

Schalldämpfer für Verbrennungsmotoren sind seit langem Stand der Technik (DE-OS 32 05 186).Silencers for internal combustion engines have long been the Technology (DE-OS 32 05 186).

Bei allen bisher bekannt gewordenen Schalldämpfern besteht das Gehäuse des Schalldämpfers aus einem Metall.The housing of all silencers that have become known so far the silencer from a metal.

Es sind bereits viele Versuche gemacht worden, das Eigenschaftsbild des am häufigsten verwendeten Stahlblechs für das Gehäuse zu verbessern. So sind beispielsweise das Verzinken oder Emaillieren des Blechs vorgeschlagen worden. Es wurde auch angeregt, das Stahlblech durch beispielsweise Aluminium oder Edelstahl zu ersetzen.Many attempts have already been made to determine the property profile of the most commonly used steel sheet to improve the case. So are, for example, galvanizing or enamelling the sheet been proposed. It was also encouraged to go through the steel sheet for example to replace aluminum or stainless steel.

Allen bisher gemachten Vorschlägen haftet jedoch die Problematik des hohen Gewichts und des sehr hohen Herstellungspreises an.However, all the proposals made so far are subject to the problem of high weight and very high manufacturing price.

Das Fertigungsverfahren für die oben beschriebenen Verfahren ist im übrigen sehr aufwendig.The manufacturing process for the processes described above is in remaining very expensive.

Korrosionsprobleme können durch oben beschriebene Maßnahmen nur in beschränktem Rahmen gelöst werden.Corrosion problems can only be solved by the measures described above limited framework can be solved.

Der Erfindung lag daher die Aufgabe zugrunde, einen Schalldämpfer zur Verfügung stellen zu können, der bei Einsatzbedingungen weitgehenst korrosionsresistent ist, zudem kostengünstig herstellbar ist, eine lange Lebensdauer im Betrieb aufweist und eine Gewichtseinsparung gegenüber herkömmlichen Schalldämpfern bietet.The invention was therefore based on the object of a silencer To be able to make available that go as far as possible under operating conditions is corrosion-resistant, is also inexpensive to manufacture, a has a long service life and saves weight compared to conventional silencers.

Diese Aufgabe wird in Verbindung mit den Merkmalen des Oberbegriffes dadurch gelöst, daß sein Außengehäuse aus Kunststoff besteht.This task is combined with the features of the generic term solved by that its outer housing is made of plastic.

Vorteilhafte Ausgestaltungen der Erfindung sind den Unteransprüchen entnehmbar. Advantageous embodiments of the invention are the subclaims removable.  

Durch die vorliegende Erfindung wird erstmals gegen alle Vorurteile der Fachwelt ein Schalldämpfer aus Kunststoff vorgestellt.The present invention is the first against all prejudices Experts presented a plastic silencer.

Durch besonders einfache Herstellungsverfahren ist der Schalldämpfer kostengünstig herstellbar. Durch den Werkstoff "Kunststoff" liegt die Lebensdauer bei einem Vielfachen eines Metall-Schalldämpfers. Gegenüber einem Metallschalldämpfer wird eine sehr hohe Gewichtseinsparung erreicht.The silencer is particularly easy to manufacture inexpensive to manufacture. Due to the material "plastic" lies Lifetime at a multiple of a metal silencer. Compared to a metal silencer, it is very high Weight saving achieved.

Nachfolgend wird anhand von Ausführungsbeispielen der Erfindung näher erläutert.In the following, examples of the invention will be used explained.

Beispiel 1example 1

Der Schichtaufbau eines erfindungsgemäßen Schalldämpfers kann beispielsweise von innen nach außen wie folgt aussehen:The layer structure of a silencer according to the invention can For example, look like this from the inside out:

  • 1. Innenbeschichtung: eine Schicht Epoxidharz mit Glaswirrgelege (Faservlies),1. Inner coating: a layer of epoxy resin with a glass interlaced scrim (Non-woven fabric),
  • 2. Trägerschicht: mehrere Schichten, z. B. drei Schichten Glasgewebe mit ungesättigtem Polyesterharz imprägniert,2. Carrier layer: several layers, e.g. B. three layers of glass fabric impregnated unsaturated polyester resin,
  • 3. Außenbeschichtung: Polyurethanschaumstoffschicht, mit ungesättigtem Polyester imprägniert.3. Outer coating: polyurethane foam layer, with unsaturated Impregnated polyester.

Selbstverständlich liegen die Harze beim Fertigprodukt in ausgehärteten Zustand vor.Of course, the resins in the finished product are cured Condition before.

Beispiel 2Example 2

Die Innenbeschichtung besteht aus einer Aluminiumfolie. Alle anderen Schichten wie Beispiel 1.The inner coating consists of an aluminum foil. All other layers as in example 1.
