Die Erfindung betrifft einen Schalldämpfer gemäß dem Oberbegriff des Hauptanspruchs.The invention relates to a silencer according to the preamble of the main claim.

Schalldämpfer sind in einer Vielzahl von Ausführungsformen bekannt und haben sich an sich bewährt.Silencers are available in a wide variety of designs and have proven themselves to be effective.

Es ist ferner ein gattungsgemäßer Schalldämpfer gemäß dem Oberbegriff des Hauptanspruchs bekannt (DE-OS 30 20 492). Dieser Schalldämpfer - ein reiner Reflexionsschalldämpfer - weist ein zylindrisches Gehäuse auf, das an seinen zwei Stirnseiten mit je einem Boden versehen ist. Durch den einen Boden ist das Abgaseintrittsrohr hineingeführt und aus dem anderen das Abgasaustrittsrohr.A generic silencer according to the preamble of the main claim is also known (DE-OS 30 20 492). This silencer - a pure reflection silencer - has a cylindrical housing, which is provided with a base on each of its two end faces. The exhaust gas inlet pipe is led through one base and the exhaust gas outlet pipe is led out of the other.

Dieser bekannte Schalldämpfer ist zwar in seiner Bereitstellung von Reflektionskammern insoweit einfacher herstellbar, als in das Gehäuse ein gesondertes Kammergehäuse eingesetzt wird. Allerdings verbleiben auch hier neben der Montage des Gehäuses und der zwei BödenThis well-known silencer is indeed easier to manufacture in terms of its provision of reflection chambers, as a separate chamber housing is inserted into the housing. However, in addition to the assembly of the housing and the two bases,

und des Kammergehäuses auch das Abgaseintrittsrohr sowie das -austrittsrohr. Insgesamt sind viele Teile einzeln herzustellen und miteinander zum Aufbau des Schalldämpfersand the chamber housing, the exhaust gas inlet pipe and the outlet pipe. Overall, many parts have to be manufactured individually and assembled together to form the silencer.

Der Erfindung liegt die Aufgabe zugrunde, einen gattungs- % gemäßen Schalldämpfer gemäß dem Oberbegriff des Hauptanepruchs einfacher herstfillhar «ii &bgr; * &ugr; &ogr; e R t a 1 h e &eegr; = The invention is based on the object of providing a generic silencer according to the preamble of the main claim of simple manufacturing «ii &bgr; * &ugr;&ogr; e R ta 1 he &eegr; =

Diese Aufgabe wird bei einem gattungsgemäßen Schalldämpfer ■ gemäß dem Oberbegriff des Hauptanspruchs erfindungsgemäß | durch dessen kennzeichnende Merkmale gelöst. $ This object is achieved in a generic silencer ■ according to the preamble of the main claim | by its characterizing features. $

Durch den nach Art eines Baukastens aufzubauenden erfin- 1 dungsgemäßen Schalldämpfer ist die gesonderte Herstellung 1 eowie der Einbau eines Abgaseintritts- oder aber Abgisaus- 1 trittsrohrs entbehrlich, weil dieses direkt an ein Teil -# '-des Kammergehäuses angeformt ist, das ganz oder teilweise \ «it Steinwolle od.dgl. zum Dämpfen des Körperschalls versehen sein kann. Infolgedessen gibt sich eine weniger aufwendige Lagerhaltung sowie eine einfachere Montage.The silencer according to the invention, which can be constructed in the manner of a modular system , eliminates the need for separate manufacture and installation of an exhaust gas inlet or outlet pipe, because this is formed directly onto a part of the chamber housing, which can be completely or partially covered with rock wool or the like to dampen structure-borne noise. This results in less expensive storage and simpler assembly.

Zweckmäßige Ausgestaltungen und Weiterbildungen der Erfin- \ dung sind in den Unteransprüchen gekennzeichnet.Appropriate embodiments and further developments of the invention are characterized in the subclaims.

Ein bevorzugtes Ausführungsbeispiel wird nachfolgend ■ unter Bezugnahme auf die Zeichnung näher erläutert. In ■ dieser zeigt:A preferred embodiment is explained in more detail below with reference to the drawing. In this:

weist ein - beim wiedergegebenen Ausführungsbeispiel eylindrisches - Gehäuse 6 auf, das an seinen beiden Enden Bit je einem Boden 7, 8 abgeschlossen ist und durch die das Abgaseintrittsrohr 9 bzw. das Abgasaustrittsrohr i0 hindurchgefühlt- ist.has a housing 6 - cylindrical in the embodiment shown - which is closed at both ends by a base 7, 8 and through which the exhaust gas inlet pipe 9 and the exhaust gas outlet pipe 10 pass.

In dem Gehäuse 6 ist insgesamt ein mit Il bezeichnetes Kammergehäuse angeordnet, welches zweigeteilt ausgebildet ist und dessen beide Hälften durch Falzen 12 (oder Clinchen, oder Nieten, oder Schweißen) verbunden sind. Das Kammergehäuse bildet eine eingangsseitige, das Abgaseintrittsrohr 9 umgebende erste Reflektionskanmer 13 auf, die mit einer Vielzahl von Öffnungen versehen ist. Das Kammergehäuse 11 ist in diesem Bereich mit Abstand von dem Gehäuse 6 angeordnet und in diesem Bereich ist es mit Steinwolle IA gefüllt.In the housing 6, a chamber housing designated II is arranged, which is divided into two parts and whose two halves are connected by folding 12 (or clinching, or riveting, or welding). The chamber housing forms a first reflection chamber 13 on the inlet side, which surrounds the exhaust gas inlet pipe 9 and is provided with a large number of openings. The chamber housing 11 is arranged at a distance from the housing 6 in this area and in this area it is filled with rock wool IA.

Im mittleren Bereich des Schalldämpfers zu Ende des Abraseintrittsrohrs 9 weitet sich die erste Reflektionskanmer 13 aus, so daß in diesem Bereich das Kammergehäuse an der Innenwandung des Gehäuses 6 unter Bildung einer rlngraumförmigen Ausbuchtung 15 anliegt.In the middle area of the silencer at the end of the abrasion inlet pipe 9, the first reflection chamber 13 expands so that in this area the chamber housing rests against the inner wall of the housing 6, forming a circular space-shaped bulge 15.

Hinter dieser ist die erste Reflektionskammer 13 mittels eines Trennbodens 16, der das Abgaseintrittsrohr 9 umgibt und an der Innenwandung des Kammergehäuses 11 anliegt, abgeschlossen.Behind this, the first reflection chamber 13 is closed off by means of a separating floor 16, which surrounds the exhaust gas inlet pipe 9 and rests against the inner wall of the chamber housing 11.

Dahinter weist das Kammergehäuse wiederum einen Abstand von der Innenwandung des Gehäuses 6 des Schalldämpfers 5 unter Bildung einer zweiten Reflektionskammer 17 auf, die sich in Richtung auf den ausgangsseitigen Boden 8 des Gehäuses 5 volumenmäßig unter Verkleinerung des Kammergehäuses 11 in diesem Bereich vergrößert und zu-Behind this, the chamber housing is again spaced from the inner wall of the housing 6 of the silencer 5, forming a second reflection chamber 17, which increases in volume in the direction of the outlet-side base 8 of the housing 5, reducing the size of the chamber housing 11 in this area and

gleich in das darin angeformte Abgasaustrittsrohr 10 übergeht und durch den Boden 8 - um ein beliebiges Maß -herausgeführt sein kann.immediately merges into the exhaust outlet pipe 10 formed therein and can be led out through the base 8 - by any desired amount.

In dem Abgaseintrittsrohr 9. dem KnmmoröehäunD &igr; &igr; »*.&agr; dem Boden 16 können -je nach akustischen Erfordernissenöffnungen 20 bzw. 21 oder 2 22 oder 23 vorgesehen sein.Depending on the acoustic requirements, openings 20 or 21 or 22 or 23 can be provided in the exhaust gas inlet pipe 9, the combustion chamber housing and the base 16.
