Abstract
An air atomizing spray nozzle for spraying a viscous liquid carrier at relatively low flow rates for agricultural and industrial applications. The nozzle comprises a hollow body with a liquid passage for receiving pressurized liquid from an external source, an air duct for receiving low pressure air from another external source, and a nozzle tip assembly. The latter includes a liquid spray tip connected to the liquid passage and having an elliptical discharge orifice formed by the intersection of a radiused end orifice bore and a cross slot communicating with the liquid passage; an air cap connected to the air duct and having a pair of diametrically opposed air nozzles straddling the liquid spray tip, each air nozzle having an outwardly diverging flat face with an oblong air orifice communicating with the air duct. Each air orifice is defined by the intersection of a radiused orifice bore and a cross slot in the flat face of the nozzle. The air nozzles are arranged with their cross slots parallel to the cross slot of the liquid spray tip and their air discharges impinge at an angle upon the discharge from the liquid spray tip to produce a relatively wide angle spray pattern of subs…
