A spray nozzle for directing a wide lateral spray curtain with substantially uniform liquid distribution throughout the length of the spray curtain is provided. The nozzle includes a nozzle body defining an elongated internal flow passage. The nozzle body includes an inlet end for connection to a pressurized liquid supply, a downstream end wall and a side wall. A discharge orifice is provided in the side wall of the nozzle body between the inlet end and the downstream end wall. The discharge orifice communicates with the internal flow passage of the nozzle body. The discharge orifice has a generally inverted teardrop configuration comprising a relatively larger area upper portion and a relatively smaller area lower portion arranged below the upper portion.

Lateral spray nozzle

A spray nozzle and method of assembly onto the threaded end of a supply line or like by use of a conventional wrench. The spray nozzle has an elongated body formed with an axial flow passageway, a threaded upstream end, a wrench engaging downstream end, and a radial locating and support flange intermediate its upstream and downstream ends for supporting the nozzle on the wrench with the downstream end in operative relation to the gripping elements of the wrench and with the threaded upstream end extending outwardly of the wrench for positioning into threaded engagement with the threaded supply line by use of the wrench. The spray nozzle has an elongated discharge orifice and the support flange has flats formed parallel to the long axis of the discharge orifice to aid in orientating the nozzle.

Screw-in type spray nozzle and method of assembly

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 substantially uniform distribution and fine particle size.
