Straight stream nozzle

摘要

A straight stream nozzle for use in directing a liquid stream at a solid surface with greater force at greater distances. The nozzle has concentric arrays of ports around a solid center. As liquid is forced through the ports, that liquid passing through the outer array of ports shields that passing through the inner array and the solid nozzle center creates a hollow center in the liquid stream which tends to promote cohesion of the inner array of streams into a single more highly concentrated stream which produces high impact at a substantial distance.
