Abstract
A nozzle (10) for emitting water, for the purpose of extinguishing fires for example, generally includes a main housing (12) for housing a barrel (62), a deflector (64), and a carrier (60). The barrel (62) supports the deflector (64) and is disposed inside of the carrier (60). When water is supplied to the nozzle (10), a locking pin (59) engages a helical groove (80) on the carrier (60). When the locking pin (59) is engaged, rotation of a spray ring assembly (18) coaxially installed around the upstream end of the nozzle (10) causes the carrier (60) and the spray ring assembly (18) to translate forward or to retract, depending on the direction of the rotation. When the carrier (60) and the spray ring assembly (18) are translated forward to the jet position, water exits the nozzle (10) as a concentrated jet stream. When the carrier (60) and the spray ring assembly (18) are retracted to the fog position, water exits the nozzle (10) as a less concentrated water spray. If the water pressure falls below a predetermined level, the locking pin (59) disengages and a carrier spring (90) between the barrel (62) and the carrier (60) causes the carrier (60) and the spray ring assembly (18) to automatically retract to the fog position.
