Abstract

Bei einer Geräuschdämpfungseinrichtung für Strömungs- und Körperschall von strömenden Medien, insbesondere Flüssigkeiten, mit einem Wellrohr und einer Anschlußmuffe ist das Wellrohr oder ein Wellschlauch (13) tief eingezogen und ummantelt ein Durchströmungsteil (10) aus einem weichen, elastischen Material, wobei eine hydraulische Trennung zwischen dem das Durchströmungsteil durchströmenden Medium und zwischen Wellrohr und Durchströmungsteil vorgesehenen Schallabbauräumen erfolgt. Bei einer Einrichtung zur Herstellung einer solchen Geräuschdämpfungseinrichtung sind Preßbackenelemente (50) vorgesehen, die eine der Außenkontur (12) des Wellschlauches entsprechende Kontur (52) aufweisen, wobei durch Aktivieren der Preßbackenelemente die Kontur des Wellschlauches über den Durchmesser so verpreßbar ist, daß eine im wesentlichen gleichbleibende Kontur und ein verringerter Durchmesser entsteht.
