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.Firefighting nozzle with a tubular inlet with an inlet opening, wherein the inlet extends along a longitudinal axis from the inlet opening in the direction of a check valve, a tubular outlet with at least one nozzle opening, wherein the outlet extends along a transverse axis running transversely to the longitudinal axis towards the nozzle opening, wherein the check valve is arranged between the inlet and the nozzle opening and seals the outlet in a sealing region relative to the inlet, characterized in that a radial distance of the sealing region from the longitudinal axis is less than or equal to a smallest radial distance of the inner circumferential surface of the inlet opening from the longitudinal axis in a region between the inlet opening and the sealing region.
