Abstract:
1. A high-pressure spray nozzle comprising: an elongate nozzle body having an upstream inlet end for coupling to a pressurized liquid supply and a downstream end, said nozzle body defining a longitudinally extending liquid flow passageway between said inlet end and a discharge orifice from which a pressurized liquid flow stream is emitted, said longitudinally extending passageway including an upstream entry section communicating with said inlet end and a downstream approach section communicating with said discharge orifice, said upstream entry section being formed with a plurality of longitudinally extending flutes defined by a plurality of circumferentially spaced outwardly extending grooves for stabilizing and directing a high-pressure liquid passing through the nozzle passageway prior to discharge from said discharge orifice and said plurality of circumferentially spaced grooves defining an outer diameter greater than the diameter of said discharge orifice.
