Abstract
The sprayhead device includes a housing () having an orifice plate () therein with at least one orifice opening () therethrough. A liquid line () delivers liquid to the sprayhead, where it proceeds through the orifice opening, wherein the liquid flow rate through the orifice and the liquid pressure are sufficiently great relative to the size of the orifice that the liquid moves through the orifice as a continuous stream. Gas is delivered to the housing and gas flows to the interior of the sprayhead through at least two openings () in the housing. The gas streams (flows) intercept the liquid flow perpendicularly, approximately 180° apart. The velocity of the gas flows is sufficient to break up the liquid stream from the orifice into a spray of droplets of desired size and velocity, accelerating them out of an acceleration duct () exit portion of the housing.
