Abstract
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.
Claims15
A nozzle for producing a straight liquid stream, said nozzle having a first plurality of axially extending through ports arrayed in a regular pattern around a solid center portion and a second plurality of transversely elongated axially extending through ports arrayed in a regular pattern radially outwardly of said first plurality of ports, each of said transversely elongated ports having a major axis and being oriented such that said major axis of each of said transversely elongated ports is substantially perpendicular to a nozzle radius such that said major axis has a greater dimension than a dimension of said transversely elongated port along the nozzle radius.
A nozzle for producing a straight liquid stream, said nozzle having a first array of X axially extending through ports arranged in a regular pattern around a solid center portion, said nozzle also having a second array of Y transversely elongated axially extending through ports arranged in a regular pattern and generally surrounding said first array of ports, each of said transversely elongated ports having a major axis and being oriented such that said major axis of each of said transversely elongated ports is substantially perpendicular to a nozzle radius such that said major axis has a greater dimension than the dimension of said transversely elongated port along the nozzle radius.
A nozzle for producing a straight liquid stream, said nozzle comprising an annular outer body and an inner core, said inner core having a first array of substantially annular axially extending through ports surrounding a solid center portion and said core and said body forming therebetween a second array of transversely elongated axially extending through ports, each of said arrays formed in a regular pattern and said second array generally surrounding said first array of ports, each of said transversely elongated ports having a major axis and being oriented such that said major axis of each of said transversely elongated port is substantially perpendicular to a nozzle radius such that said major axis has a greater dimension than the dimension of said transversely elongated port along the nozzle radius.
