Description

Es sind .Einrichtungen zur Schalldämpfung für das Ansauggeräusch von mit Filtern versehenen Verdichtern und Gebläsen bekannt, die aus Iabyrint'hartig angeordneten D,ämpfung§körpern bestehen. Die Erfindung bezieht sich auf eine Einrichtung dieser Art und besteht darin, daß die labyrinthartigen Dämpfungskörper in der Filterkammer auf,der Reinluftseite des Filters angeordnet sind. Bei einer solchen Anor,dtu -ng der labyrinthartigen Dämpfungskörper liegen diese näher an der Schallquelle, und ;man erzielt daher eine besonders wirksame Dämpfung. Außerdem wird so vermieden, daß durch Reflexion in der großen Filterkammer eine Venstärkung .des Schalles eintritt. Ein weiterer Vorteil liegt darin, daß die Labyrinth#körper nur von gereinigter Luft be-aufschlagt und so vor einer Verschmutzung bewahrt werden.There are devices for soundproofing the suction noise of Filtered compressors and fans known from Iabyrint'hartig arranged D, damping bodies exist. The invention relates to a device this type and consists in that the labyrinthine damping body in the filter chamber are arranged on the clean air side of the filter. With such an anor, dtu -ng the labyrinth-like damping body, these are closer to the sound source, and ; a particularly effective damping is therefore achieved. It also avoids that through reflection in the large filter chamber a reinforcement of the sound occurs. Another advantage is that the labyrinth # body is only from purified air be charged and thus protected from contamination.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung in einem Längsschnitt dargestellt.An embodiment of the invention is shown in the drawing in one Longitudinal section shown.

In der Ansaugeleitung des nicht gezeigten Verdichters oder Gebläses ist eine Kammeer io vor-Üanden, die das Luftfilter i i und den ;Schalldämpfer 12 enthält. D.ie Luft tritt bei 13 durch Leitbleche möglichst. gleichmäßig auf den ganzen Querschnitt verteilt in die Kammer io ein, diurchsträmt das Filter ii u .nd gelangt dann in den. Scharfdämpfer 12, ,dessen einzelne Dä.mpfungskörper so angeordnet sind- daß sie der Luft einen Labyrinthweg vorschreiben. Bei 1q. ist die Kammer io an den Verdichter bzw. an das Gebläse angeschlossen. Die in entgegengesetzter Richtung lammenden Schallwellen werden von den großen Flächen des Schalldämpfers 12 aufgefangen, und zwar in unmittelbarer Nähe des Verdichters bzw. des Gebläses und ohne daß eine nennenswerte Verstärkung durch Reflexion an den Wandungen der Kammer io eintreten kann. Der Schal-fdämpfer 12 wird: dabei ausschließlich von gereinigter Luft beanfschlagt, so d'aß ein Verschmutzen verhindert wird.In the suction line of the compressor or fan, not shown is a chamber io in front of which the air filter i i and the; muffler 12 contains. D. The air passes through baffles at 13 if possible. evenly on the whole cross-section distributed in the chamber io, di-flow through the filter ii and .nd then gets into the. Sharp damper 12, whose individual damping bodies are arranged in this way are - that they dictate a labyrinth path for the air. At 1q. is the chamber ok connected to the compressor or to the fan. The one in the opposite direction Lambing sound waves are picked up by the large surfaces of the silencer 12, in the immediate vicinity of the compressor or the fan and without one Significant amplification occur through reflection on the walls of the chamber io can. The sound absorber 12 is: only acted upon by purified air, so that contamination is prevented.
