Abstract
A pattern adjustable flow nozzle which maintains a constant fluid flow rate is disclosed. The flow nozzle is comprised of two parts, an inner tubular body and an outer tubular sleeve, rotatable one on the other. Orifices are disposed on the output end of the tubular body and tubular sleeve, and the superposition of those orifices in various rotational alignments determines the throw and pattern of the ejected fluid. Flow cavities on the inner tubular body allow for a constant rate of fluid flow over the range of orifice superpositions.
