Abstract:
1. A liquid spray nozzle comprising a nozzle body having a liquid inlet and a discharge orifice, said nozzle body having a liquid flow passage that includes an inlet section communicating with said liquid inlet for directing a pressurized liquid flow stream through said nozzle body to said discharge orifice, said liquid flow passage including a relatively small diameter nozzling zone having a longitudinal axis for accelerating the liquid flow stream directed through said nozzle body in a longitudinal direction and creating a pressure drop therein prior to discharge from said discharge orifice, said nozzle body having an ambient air passage having an inlet in communication with ambient air outside said nozzle, said ambient air passage including an venturi passage communicating with said nozzling zone transversely to the longitudinal axes of said nozzling zone such that a pressurized liquid flow stream passing through said nozzling zone draws ambient air in said ambient air inlet and venturi passage for mixing with the liquid flow stream prior to discharge from said discharge orifice, and said discharge orifice being eccentrically located relative to the longitudinal axis of said nozzling zone and the discharge of the accelerated liquid flow stream from said nozzling zone for altering the direction of the discharging liquid flow stream from said nozzling zone prior to discharge from said discharge orifice.
