Abstract
A water mist nozzle () for a fire suppression system comprises a nozzle head () including a discharge nozzle () for supplying a fluid jet (); a support structure (); and a stationary deflector element (). The stationary deflector element () is fastened to the support structure () and comprises a body with a substantially round outer periphery having a base portion () and a substantially conical upper portion () with a central peak (). The substantially conical upper portion () provides a plurality of flowpaths (), the flowpaths () extending substantially radially from a radial position close to the central peak () in a direction towards the outer periphery, the flowpaths () having at least one portion () of decreasing slope, in which the slope of the bottom of the flowpaths () decreases along the flow direction towards the outer periphery. The stationary deflector element () is fastened to the support structure () such that the central peak () of the substantially conical upper portion () of the stationary deflector element () faces the discharge nozzle () and that the fluid jet () exiting the discharge nozzle () impinges onto the central peak () and is distributed to the environment, substantially in a lateral direction, through the plurality of flowpaths ().
