Schalldämpfer für Gebläse. Patentiert im Deutschen Reiche vom 4. April 1909 ab.Blower silencers. Patented in the German Empire on April 4 , 1909.

Rotierende Gebläse \'erursachen infolge Abschneidens der verhältnismäßig schnell strömenden Luftsäule durch die Flügel ein mehr oder weniger störendes Luftgeräusch. Zweck dieser Erfindung ist, diese Schallwellen zu vernichten bzw. in ein strömendes Geräusch umzuformen. Um dieses zu erreichen, läßt man die Schallwellen auf eine Stoff membran oder weiche, elastische Fläche stoßen, welcheRotating fans cause cutting off the relatively fast flowing air column through the wings a more or less disturbing air noise. purpose This invention is to annihilate these sound waves or turn them into a flowing sound to reshape. To achieve this, one lets the sound waves on a fabric membrane or soft, elastic surface, which

ίο in einem erweiterten, trichterförmigen Behälter eingeschlossen ist.ίο in an enlarged, funnel-shaped container is included.

Fig. ι zeigt einen Schalldämpfer für die Säugöffnung bei Druckgebläsen. Hierbei ist a die Stoffmembran, b der Gebläsesaugstutzen, c das Führungsrohr, d das trichterförmige Gehäuse, e das Lufteintrittsrohr.Fig. Ι shows a silencer for the suction opening in pressure blowers. Here, a is the polymer membrane, the Gebläsesaugstutzen b, c the guide tube, the funnel-shaped housing, e d, the air inlet pipe.

Fig. 2 ist ein Schalldämpfer für den Auspuff bei Sauggebläsen. Die- Ausführung ist ähnlich dem ersteren Schalldämpfer. Auch hier ist mit α die Stoffmembran, b der Gebläsedruckstutzen, c das Führungsrohr, d das trichterförmige Gehäuse und e der Austrittsstutzen bezeichnet. Fig. 2 is a muffler for the exhaust in suction fans. The design is similar to the former silencer. Here, too, α denotes the fabric membrane, b the blower pressure nozzle, c the guide tube, d the funnel-shaped housing and e the outlet nozzle.
