ABSTRACT:
A nozzle unit comprising a frusto-conical nozzle having a transverse flat end face, an outlet passage formed in this flat end face, an inner conduit member which in use is connected to a source of air under pressure, a water conduit which in use is connected to a source of water under pressure, and a mixing chamber in which the water and air is mixed and from which the mixture passes to be discharged through the outlet passage. The nozzle unit further has a concave cylindrical cap which is carried by rigid carrier means which is integral with the nozzle and into which the water/air mixture is discharged, the water being there broken down into very small droplets. The mixing chamber has a passage therethrough in the form of a venturi and inlet bores from the exterior of the chamber to just downstream of the venturi throat. In use, air passes through the venturi throat and the water is drawn in through the bores to the interior of the venturi throat and is there mixed with and entrained in the air.
