Abstract (en)
A nozzle has a body 101 with a central cavity 103 from which a plurality of fire extinguishant fluid outlets 109B extend. The outlets extend non-radially with respect to the central axis 135 of the cavity 103, i.e. at least a portion of each outlet is inclined with respect to any plane parallel to and passing through the central axis of the cavity which intersects the portion of the outlet. The extinguishant from the non-radial outlets 109B is thrown towards the walls of the chamber 139, along the paths 141. The jets of the fluid induce a rotational movement within the ambient fluid (for example, air) already present in the chamber, thus creating a vortex or rotational movement of the fluid within the chamber 139. In another embodiment, the vortex or rotational movement is generated by a nozzle assembly of generally cruciform configuration with three or more discharge tubes having outlets formed therein for discharging extinguishant in equi-angularly-spaced directions. <IMAGE>
