Abstract:
An air assisted spray nozzle comprising:a hollow body having a mixing and atomizing chamber, an air inlet orifice through which a pressurized air stream is directed into said mixing and atomizing chamber, and a liquid inlet orifice through which a liquid stream is directed into said mixing and atomizing chamber at an angle to a direction of said pressurized air stream, an impingement post extending into said chamber, said post being in substantial alignment with said liquid inlet orifice and having an end face against which the liquid stream directed into said chamber from said liquid inlet orifice impinges, said post being disposed transversely to the direction of travel of said pressurized air stream directed into said chamber from said air inlet orifice, said impingement post end face being formed with an inwardly directed recess for receiving the liquid stream introduced into said chamber from said liquid inlet orifice and directing the liquid away from the end face for enhanced intermixing by the pressurized air stream introduced into said mixing and atomizing chamber from said air inlet for breaking down and atomizing of the liquid, and a spray tip having a discharge orifice in fluid communication with said mixing and atomization chamber and through which said atomized liquid is discharged in a predetermined spraying pattern.
