Abstract : The patent relates to an oscillating liquid nozzle for use in producing foam for fires, having a fluidic oscillating device attached to the nozzle exit with a pair of inner wall members spaced from the nozzle exit to form control ports. Outer wall members connect to the nozzle body and have scoop members positioned at their forward end which extend into the flow forward of the inner wall members to return a portion of the flow to the control ports and cause oscillation of the liquid stream leaving the nozzle exit.
