Abstract

Kraftstoffeinspritzvorrichtung für eine Gasturbinen-Brennkammer mit einer flüssigkeitsgekühlten Einspritzdüse (1), die ein ein Kraftstoff-Führungsrohr (4) mit Abstand umgebendes Kühlflüssigkeits-Rohr (10) aufweist, welches nahe der Düsen-Austrittsöffnung (7) in einen Ringraum (9) für die Kühlflüssigkeit mündet oder diesen das Kraftstoff-Führungsrohr direkt umgebenden Ringraum bildet, wobei innerhalb des Kühlflüssigkeits-Rohres bezüglich der Kraftstoff-Strömungsrichtung stromauf des Ringraumes ein das Kraftstoff-Führungsrohr umgebendes Trennwand-Element (11) vorgesehen ist, welches den Innenraum des Kühlflüssigkeits-Rohres in zwei Raumsegmente (12A,12B) unterteilt, wobei das erste Raumsegment mit einem Zuführkanal (13) und das zweite Raumsegment mit einem Abführkanal (14) für die Kühlflüssigkeit verbunden ist.
