Abstract: A cyclonic spray nozzle having a substantially cylindrical inlet chamber with a closed top end, an open bottom end and a tangential air inlet arranged adjacent to the closed top end. A truncated Cone-shaped discharge chamber having an open top end and an open bottom end of smaller diameter than the open top end, is secured to said open bottom end of said inlet chamber in axial, fluid communicating register therewith. A fluid injector nozzle is positioned within the discharge chamber in operative spraying relation to said open end of said discharge chamber. The nozzle is useful in spraying an axially directed mist of fluid over a relatively long distance, while containing radial overspray.
