Abstract (en)
[origin: WO2021228470A1] The invention relates to a fire-fighting nozzle, comprising: - a tubular inlet having an inlet opening, the inlet extending along a longitudinal axis from the inlet opening toward a shut-off valve; - a tubular outlet having at least one nozzle opening, the outlet extending along a transverse axis, which runs transversely to the longitudinal axis, toward the nozzle opening, and the shut-off valve being disposed between the inlet and the nozzle opening and sealing off the outlet from the inlet in a sealing region, characterized in that the radial distance of the sealing region from the longitudinal axis is less than or equal to the smallest radial distance of the inner lateral surface of the inlet opening from the longitudinal axis in a region between the inlet opening and the sealing region.
