Abstract: A fog or mist generating nozzle assembly produces a swirling fog pattern having a forward thrust component that permits an operator, stationed safely at a remote location relative to a fire source, to exercise directional control and positioning of a relatively large mist cloud on or about the fire source. The discharge nozzle includes a cylindrical bearing member and a cylindrical rotor member with multiple water discharge orifices that extend at a forward projection angle a relative to the nozzle axis. A pair of fog producing nozzles are configured with counter-rotating rotors, producing counter-rotating clouds that merge along a common vortex. This generates a composite mist cloud having a magnified forward thrust component, enabling remote directional control of the mist cloud.

Abstract: A fog or mist generator nozzle produces a fog pattern having a forward thrust component that permits an operator, stationed safely at a remote location relative to a fire source, to exercise directional control and positioning of a relatively large volume of fog or mist on or about a fire source. The discharge nozzle includes a cylindrical bearing member and a cylindrical sleeve member with a plurality of water discharge orifices. The orifices extend at a forward projection angle, transverse to the nozzle axis for producing a swirling (rotating) fog pattern that has a forward thrust vector component. A pair of the fog producing nozzles are configured with counter-rotating rotors. Each nozzle generates a swirling (rotating) fog pattern that swirls in counter-rotation relation to the other.
