ABSTRACT:
A novel center vane is disclosed for use in a full or solid cone spray nozzle. The vane has a solid center and specific parameters are set forth, in relation to the nozzle size and orifice diameter, for the vane geometry so that a solid spray cone of uniform distribution is obtained. In particular, we have found that when the orifice diameter is less than half of the nozzle diameter, the vane recess depth is a critical dimension to obtain a uniform fluid particle distribution in the solid cone spray and specifically have found that if the orifice diameter is equal to or greater than one-half the pipe or nozzle diameter, the vane recess depth should be one-fourth (0.25) of the pipe diameter, but if the orifice diameter is less than half of the pipe or nozzle diameter, the vane recess depth in inches should be equal to the orifice diameter squared divided by the nozzle diameter.
