Abstract

Brandbekämpfungsdüse mit einem rohrförmigen Einlass mit einer Einlassöffnung, wobei sich der Einlass entlang einer Längsachse von der Einlassöffnung in Richtung eines Sperrventils erstreckt, einem rohrförmigen Auslass mit zumindest einer Düsenöffnung, wobei sich der Auslass entlang einer quer zur Längsachse verlaufenden Querachse hin zur Düsenöffnung erstreckt, wobei das Sperrventil zwischen dem Einlass und der Düsenöffnung angeordnet ist und den Auslass in einem Dichtbereich gegenüber dem Einlass abdichtet, dadurch gekennzeichnet, dass ein radialer Abstand des Dichtbereichs von der Längsachse kleiner oder gleich einem kleinsten radialen Abstand der inneren Mantelfläche der Einlassöffnung von der Längsachse in einem Bereich zwischen der Einlassöffnung und dem Dichtbereich ist.
