Abstract
The invention relates to a spray mist nozzle, in particular an open high-pressure spray mist nozzle for firefighting systems, having a housing which is configured with an extinguishing fluid inlet and is configured with multiple recesses for receiving an exchangeable nozzle insert, such a nozzle insert being inserted into one, multiple/plural or all the recesses. The nozzle insert has a main body with a longitudinal axis that has in the longitudinal axis a spray mist outlet for the extinguishing fluid. An exchangeable swirl body is arranged in the main body and is configured to swirl the extinguishing fluid prior to the latter exiting from the spray mist outlet. The spray mist outlet has a minimum opening cross section, and has a widened exit cross section downstream of the minimum opening cross section, wherein a transition from the minimum opening cross section to the exit cross section runs along a convexly curved surface.
