Abstract: 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.

Abstract: 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.
