Abstract
A full cone spray nozzle having a vane which comprises a plurality of vane segments each disposed in a respective quadrant of a vane chamber and formed with respective flat ramp surfaces and concave surfaces which divide the incoming liquid into two flow streams and impart vortical and turbulent movement to the liquid such that the liquid discharged from the nozzle has a conical spray pattern with liquid particles distributed throughout the spray pattern. The vane chamber is formed with outwardly extended recesses adjacent and across from concave surfaces of the vane segments for ensuring maximum free tangential passage of solids through the vane without affecting the liquid flow rate. In one embodiment the recesses are in the form of slots in a cylindrical mounting ring of the vane segments and in another embodiment the recesses are outwardly extending grooves in a cylindrical wall of the nozzle body which defines the vane chamber.
