Abstract

Die Erfindung bezieht sich auf einen Schalldämpfer (1) zur Dämpfung der Ansauggeräusche von Kompressoren und/oder zur Dämpfung von Ablassgeräuschen aus Druckluftsystemen.
Zwecks weiterer Absenkung des Schallpegels - insbesondere der Ablassgeräusche - bei kompakten Abmessungen und geringem Gewicht schlägt der Erfinder vor, dass im Inneren des Schalldämpfers (1) Prallwände (6) angeordnet sind, die (6) schräg zur grundsätzlichen Durchströmrichtung verlaufen und der durchströmenden Luft einen mäanderförmigen Strömungsweg aufzwingen. Dabei verlaufen vorzugsweise die schrägen Prallwände (6) zueinander parallel.
Zur weiteren Pegelabsenkung ist vorzugsweise in der Nähe der Niederdrucköffnung (5) offenporiger Schaumstoff (3) eingebracht.
