ABSTRACT:
This disclosure relates to an improved foam aeration nozzle comprising a peripheral jet nozzle, a spray collector which receives the jet and produces a fully filled spray, and an aeration device which agitates and aerates the spray and produces the foam. In use, the peripheral jet nozzle produces an annular cone-shaped spray or sheet of water. A collector is attached to the nozzle, the collector including a tubular wall in the path of the conical spray. The collector further includes an annular obstruction, and the water, as it moves along the wall surface, strikes the obstruction. At least a portion of the water is deflected toward the axis of the nozzle by the obstruction to produce a fully filled spray. An aeration device downstream of the obstruction is located to be impinged by the fully filled spray and to convert the spray to a foam and to discharge the foam on an intended target at a useful distance.
