ABSTRACT:
A full cone liquid spray nozzle is provided. The spray nozzle includes a nozzle body having a discharge orifice at a downstream end and an inlet at an upstream end for connection to a liquid supply. A liquid flow passageway extends through the nozzle body communicating between the inlet and the discharge orifice. A vane is disposed in the liquid flow passageway upstream of the discharge orifice. The vane has a plurality of V-shaped passageways therein. Each V-shaped passageway extends inward at an angle with respect to a longitudinal axis of the vane between an upstream face and downstream face of the vane. A whirl and mixing chamber defined by the liquid flow passageway is arranged between the vane and the discharge orifice.
