Abstract
The invention comprises an atomizing spray nozzle containing multiple restrictions to the flow of an air and water mixture through the nozzle created by contours in the stem in relation to the orifice and having a whirl chamber in the nozzle body where injected air induces disturbances in the liquid to create effective atomization prior to the first restriction which creates a negative pressure beyond the restriction and which is repeated at additional restrictions thus resulting in a repeated depressurization and sudden expansion to obtain a finely atomized mixture before reaching the orifice, with a final restriction at an outlet that may take the form for a flat spray or one for a narrow round spray.
