Description

Die Erfindung betrifft eine weitere Verbesserung des durch Patent 511 490 geschützten Schalldämpfers für Kraftfahrzeuge u. dgl. Während bei der im Hauptpatent beschriebenen Ausführung nur ein Rohr mit hintereinanderliegenden und unmittelbar aneinanderstoßenden Düsen vorgesehen ist, sind gemäß der Erfindung neben dem. Hauptauspuffrohr mehrere mit diesem in Verbindung stehende Nebenrohre angeordnet, in denen die Düsen gleichfalls hintereinanderliegen und jede Düse ein für sich einsetzbarer und auswechselbarer Teil ist. Durch diese Verteilung der Abgase können sie schneller entweichen, so daß eine günstigere Wirkung und wirksamere Entlastung für die Maschine erreicht wird. In der Zeichnung ist der Erfindungsgegenstand beispielsweise veranschaulicht. Es zeigen Abb. ι einen Längsschnitt, Abb. 2 einenThe invention relates to a further improvement on that protected by patent 511,490 Silencer for motor vehicles and the like. While described in the main patent Execution only one tube with one behind the other and directly abutting one another Nozzles are provided according to the invention in addition to the. Main exhaust pipe arranged several associated with this secondary pipes in which the nozzles also lie one behind the other and each nozzle can be used and exchanged for itself Part is. Through this distribution of the exhaust gases, they can escape more quickly, so that a more favorable effect and more effective Relief for the machine is achieved. The subject of the invention is shown in the drawing for example illustrated. It shows Fig. Ι a longitudinal section, Fig. 2 a

ao Schnitt nach a-b der Abb. 1, Abb. 3 einen Gußkörper im Grundriß und Abb. 4 einen Längsschnitt hiervon.ao section on AB of Fig. 1, Fig. 3 is a casting in plan and fig. 4 shows a longitudinal section thereof.

Neben dem Auspuffrohr«, in welchem die Düsen b in bekannter Weise eingesetzt sind, sind mehrere, beispielsweise zwei Rohre c angeordnet, die mit dem Rohre e durch Öffnungen d in Verbindung stehen. In diesen Rohren sind die Düsen b gleichfalls so eingesetzt, daß jede Düse ein für sich einsetzbarer und auswechselbarer Teil ist. Ein Teil der durchströmenden Gase tritt in die Rohre c ein, wodurch ein schnelleres Entweichen stattfindet. Die Rohre sind am vorderen Ende durch einen abnehmbaren, mit Austrittsöffnungen versehenen Deckel e miteinander verbunden. \In addition to the exhaust pipe, in which the nozzles b are inserted in a known manner, several, for example two pipes c are arranged, which are connected to the pipe e through openings d . The nozzles b are also inserted in these tubes in such a way that each nozzle is a part that can be used and replaced by itself. A part of the gases flowing through enters the pipes c , whereby a faster escape takes place. The tubes are connected to one another at the front end by a removable cover e provided with outlet openings. \

Bei der Ausführungsform nach Abb. 3 und 4 ist statt der Rohre ein aus zwei flachen Teilen bestehender Gußkörper/ vorgesehen mit hintereinander- und nebeneinanderliegenden eingegossenen Düsen b. Die beiden Gußkörperhälften werden in geeigneter Weise, beispielsweise durch Schrauben o. dgl., zusammengehalten. In the embodiment according to FIGS. 3 and 4, instead of the tubes, a cast body consisting of two flat parts / is provided with cast-in nozzles b one behind the other and next to one another. The two cast body halves are held together in a suitable manner, for example by screws or the like.
