MULTIFUNCTION NOZZLE Abstract of the Disclosure A multifunction nozzle including a peripheral jet nozzle having a first end adapted to be connected to a liquid supply and a second end from which the jet is ejected. The liquid may be plain water or a mixture of water and a foam concentrate. The peripheral jet nozzle is adjustable between straight stream and fog positions. The multifunction nozzle further comprises a sleeve which is attached to and surrounds the peripheral jet nozzle, the sleeve being movable relative to the jet nozzle in the direction of the nozzle axis and the flow of the liquid. The sleeve is movable between a forwardly extended or foam position and a rearwardly retracted or inoperative position. When the sleeve is in the retracted pos- ition it is out of the path of the liquid jet and the nozzle may be used in either the straight stream or fog modes. When the sleeve is moved forwardly to the extended position and the peripheral jet nozzle is placed in the fog mode, the diverging liquid jet strikes the inner surface of the sleeve. An agi- tator is attached to the inner surface of the sleeve and causes the jet to break into fine particles. In the instance where the jet includes a mixture of water and foam concentrate, air is introduced into the mixture within the sleeve, and a dense foam is ejected. The nozzle may also be used in the straight stream mode when the sleeve is in the extended position.
