Patent ID: 7611080

Claim:
A full cone liquid spray nozzle comprising: 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 extending through the nozzle body communicating between the inlet and the discharge orifice; a vane having an outer perimeter disposed in fixed engaging relation with the nozzle body liquid flow passageway upstream of the discharge orifice, said vane having circular upstream and downstream end faces, said vane having a plurality of V-shaped passageways therein each extending through the outer perimeter of the vane between and through said upstream face and downstream face of the vane; a whirl and mixing chamber defined by the liquid flow passageway between the vane and the discharge orifice; said V-shaped passageways each having a pair of opposed sidewalls at an acute angle to each other that define a straight line apex at an angle to and in a different plane than the longitudinal axis of the vane, said opposed side walls of each V-shaped passageway extending from the straight line apex of the passageway to an outer perimeter of the downstream face of the vane, and said vane having an axial length less than the diameter of said downstream face.
