Description

Sie Erfindung bezieht eioh auf einen Auspufftopf, insbesondere für Yerbrennungsmotoren, der aus zwei entlang ihres ganzen Uafangs mit Ausnahme der Gasein- und -auBgangsöffnungen ausammengeschweißten Metallsohalen besteht.You invention relates eioh to a muffler, especially for internal combustion engines, which consist of two along their entire Uafangs with the exception of the gas inlet and -Output openings made of welded metal brackets consists.

Bekannte Auspufftopfe dieser Art haben eine verhältnismäßig große Diokenabmessung und ermöglichen daher nioht in allen Fällen eine optimale Eaumausnutxung am Fahrzeug. Außerdem haben die bekannten Ausführungen im allgemeinen einen relatir komplizierten Aufbau, der nur mit Hilfe τοη einzelnen Hietstellen und SohweißungenKnown mufflers of this type have a relatively large diameter and therefore do not allow optimal use of space in all cases at the vehicle. In addition, the known designs generally have a relatively complicated structure, the only with the help of individual hot spots and weldings

Die Aufgabe der Erfindung besteht darin, einen einfach herzustellenden, sehr flaohen Auspufftopf zu schaffen, der eine geringe Korrosionsempfindliohkeit aufweist.The object of the invention is to provide a very fluffy muffler that is easy to manufacture Create that has a low sensitivity to corrosion.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß die Sοhaien einen annähernd flaohen Behälter bilden und im Inneren des Auspufftopfes zusammengeschweißte und nioht zusammengeschweißte Flaohen haben, so daß zwischen der Eingangs- und der Ausgangsöffnung eine Reihe von untereinander in Verbindung stehenden Kammern entstehen, und daß der Durchgangsquerschnitt für die Gase starke und plötzliche Veränderungen mehr oder weniger tiber die ganze Xtänge eines Wegea aufweist, dem die Grase deutlioh ununterbrochen folgen.According to the invention this object is achieved in that the sea sharks form an approximately flat container and inside the muffler have welded and not welded flaohen, so that between the inlet and outlet openings a series of Interconnected chambers arise, and that the passage cross-section for the gases is strong and sudden changes more or less over the whole length of a path a which the grass clearly shows follow continuously.

Ein besonders zweckmäßiges und einfaohes Verfahren zum Herstellen eines derartigen Auspufftopfes besteht darin, daß zwei ebene Bleohe, vorzugsweise aus Leiohtlegierung, duroh Walzung aneinandergesohweißt werden, wobei alle Bereiohe, duroh welche die Gase strömen massen, im voraus mit einem nioht sohweißbaren MaterialA particularly useful and simple method for manufacturing such a muffler is that two flat Bleohe, preferably from Borrowed alloy, duroh rolling, are welded together, with all areas through which the gases flow mass, in advance with a non-weldable material

In Fig. 3 folgt der öffnung 1 eine relativ große Kammer 3» während die Ausgangsöffnung vor einer ähnlichen Kammer 5 liegt. Sie zwei Kammern stehen mittels eines parallelen und anliegenden Hohrbtindels 4- geringen Querschnitts in Verbindung, wobei die Bleohe entlang den Trennungslinien der Rohre zusammengeschweißt sind.In FIG. 3, the opening 1 is followed by a relatively large one Chamber 3 »while the exit opening is in front of a similar chamber 5. You two chambers stand by means of one parallel and adjacent Hohrbtindels 4-low Cross-section in connection, the leads are welded together along the lines of separation of the pipes.

In Fig. 5 besitzt der Weg die Form eines Rechtecks und steht stellenweise mit Kammern 6 verschiedener Größe in Verbindung, wobei diese Kammern im Innern des Reohteoks angeordnet sind. Dieses Rechteck kann durch einen Kreis, ein Oval od. dgl. ersetzt werden.In Fig. 5 the path has the shape of a rectangle and is in places with chambers 6 of different sizes in connection, these chambers being arranged in the interior of the Reohteok. This rectangle can be replaced by a Circle, oval or the like. Be replaced.

Alle Auspufftöpfe werden nach dem eben erwähnten Herstellungsverfahren gefertigt, das darin besteht, die nioht-gesohweißten iüeile, warmgewalzte Aluminiumbleche (oder Aluminium-Legierung) warmzuwalzen und nachher duroh Aufblasen in die gewünschte Form zu bringen. Ein solches Verfahren ist z. B. in den französischen Patentschriften 1 077 791 und 1 110 849 beschrieben.All mufflers are made according to the above Manufacturing process that consists of non-welded, hot-rolled aluminum sheets (or aluminum alloy) to be hot-rolled and then brought into the desired shape by means of inflation. One such Procedure is z. As described in French patents 1,077,791 and 1,110,849.

Die Anwendung dieses Verfahrens erlaubt es, auf einfache Weise viele Varianten der inneren Kreiswege von Auspufftopfen zu verwirklichen, wobei diese letzteren keine Abdichtungen, Verbindungsdiohtungen, Vernietungs-The application of this method allows many variants of the inner circular paths of Realize mufflers, the latter being the latter no seals, connecting seals, riveting

Das angewendete Metall, Aluminium oder Leiohtlegierung, widersteht der Korrosion, insbesondere der Schwefelsäure oder schwefeligen Säure, die sioh aus dem Schwefel bilden, der in den verbrannten Gasen bleibt. Dieses Metall leistet der Feuchtigkeit Widerstand und ist rostfrei. Der Widerstand gegenüber der Korrosion kann noch durch Oberflächenbehandlung oder Plattierung verbessert werden.The metal, aluminum or borrowed alloy used, resists corrosion, especially the sulfuric acid or sulphurous acid that sioh from the Form sulfur which remains in the burned gases. This metal resists moisture and is rustproof. The resistance to corrosion can be further enhanced by surface treatment or plating be improved.

Duroh die große Leitfähigkeit des Metalls und die Möglichkeit, die Ausdehnungsbereiohe in einem verminderten Raum zu vergrößern, kann das erfindungsgemäße Auspuffrohr im Hinblick auf die bekannten Arten geringere Abmessungen aufweisen, wobei es aus einem Stück gegossen sein und eine flache Form besitzen kann.Duroh the great conductivity of the metal and the possibility of the expansion area in a diminished The exhaust pipe according to the invention can increase space have smaller dimensions with respect to the known types, being cast in one piece can be and have a flat shape.
