Abstract:
A full cone spray nozzle comprising:a nozzle body, a liquid flow passage through said body defined by an inlet in said body, a vane chamber downstream of said inlet, a whirl chamber downstream of the vane chamber, and a discharge orifice, a vane disposed within said vane chamber for imparting vortical and turbulent movement in a liquid flow stream passing through said vane and into said whirl chamber, said vane including a pair of segments disposed in different quadrants of said vane chamber, said segments defining an upstream flat entry ramp surface and a downstream concave surface such that a liquid flow stream passing through said vane is directed by said flat entry ramp surface in a downstream axial direction onto said concave surface which tangentially directs the liquid flow stream and creates turbulence and liquid is break down such that liquid emitted from said discharge orifice has a conical shaped spray pattern with liquid particles distributed through the spray pattern.
