ABSTRACT:
A nozzle body that provides a substantially uniformly distributed spray over 180.degree. at the discharge end in which the uniformly distributed spray in the form of solid cone is created by an inner nozzle and a uniformly distributed spray of a hollow cone is created by an outer nozzle and in which the spray from the inner and outer nozzles are immediately adjacent one another. The construction of the nozzle body is such that although the inner and outer nozzle each initially create their own spray pattern, the end result is a combined solid cone spray that could not be created by either the inner or outer nozzle alone. The nozzle body has a center vane for the inner nozzle to ensure an inner solid cone spray and may have a metering plate to direct some fluid to the outer nozzle so that the end result is a spray that is a solid cone with an angle substantially in excess of the cone created by the inner nozzle alone and having a coefficient discharge of approximately 0.99. An alternate novel feature for a fourth embodiment combined the function of the metering plate and center vane in a single disc shaped unit which permits a substantial reduction in the overall length of the nozzle body. The combination of an inner and outer nozzle to create an 180.degree. full solid cone liquid will be particularly useful for applying liquid such as water for fixed sprinklers for fire supression systems, for roof cooling, etc.
