Abstract

Beschrieben wird eine Zweistoffsprühdüse mit einer Mischkammer (16), in der ein Prallkörper vorgesehen ist, auf den der Flüssigkeitsstrahl auftrifft. Der Prallkörper ist dabei als ein koaxial zu dem Flüssigkeitsstrahl ausgerichteter sich in Strömungsrichtung bis zu einer Abreißkante (15) erweiternder Verdrängungskörper (6) ausgebildet, der insbesondere kegelförmig sein kann. Die Zufuhrkanäle (17) für das gasförmige Medium münden in Strömungsrichtung vor der Abreißkante (15), so dass die zugeführte Druckluft den in einen Flüssigkeitsring in der Form eines Flüssigkeitsfilmes aufgelösten Flüssigkeitsstrahl wirksam in feine Tropfen gleichmäßig verteilen kann.
