Abstract

Die Erfindung betrifft eine zweistufige Druckzerstäuberdüse mit einem Düsenkörper (30) mit Mischkammer (39), welche über eine Düsenaustrittsbohrung (33) mit einem Aussenraum in Verbindung steht und mit einem ersten Zufuhrkanal (42) mit einer Zuführungbohrung (41) für eine zu zerstäubende Flüssigkeit (37), durch welche besagte Flüssigkeit (37) drallfrei und unter Druck zuführbar ist, wobei in die Kammer (39) mindestens ein weiterer Zufuhrkanal (36) für einen Teil der zu zerstäubenden Flüssigkeit (37) oder für eine zweite zu zerstäubende Flüssigkeit (37') mündet, durch welchen besagte Flüssigkeit (37, 37') unter Druck und mit Drall zuführbar ist. Die Zuführungsbohrung (41) des ersten Zufuhrkanales (42) liegt mit der Düsenaustrittsbohrung (33) auf einer Achse (34). Sie ist dadurch gekennzeichnet, dass der austrittsseitige Durchmesser (da) der Düsenaustrittsbohrung (33) höchstens so gross ist wie der Durchmesser (dz) der Zuführungsbohrung (41) und die Länge (L) der Düsenaustrittsbohrung (33) mindestens das 2- bis maximal 10-fache des austrittsseitigen Durchmessers (da) der Düsenaustrittsbohrung (33) beträgt.
