ABSTRACT:
A firefighting nozzle includes a nozzle body having a having a centrally formed jet orifice at its outlet end. An annular fog spray opening concentrically surrounds the jet orifice. A jet control valve is provided for allowing selective variation of the diameter of the solid stream emitted from the jet orifice. A fog control valve is provided for selectively varying the intensity of the discharge from the fog spray opening. The jet control valve and the fog control valve are operable independently of and simultaneously with one another, so that either a variable diameter solid stream or a variable fog cone, or both, can be produced at once. Various remote control arrangements are available for actuating the jet and fog control valves.
