<p>A nozzle body (100) and coupler bearing assembly (355) for discharging a liquid material. The nozzle body consists of approximately thirty-two serially and concentrically arranged ports (140) which receives liquid from an attached hose (400) under high pressures. The various points of placement of the ports, combined with the rotation produce a balanced and stabilized effect on the rotating nozzle assembly which allows the nozzle assembly to be delivered to a target area, and while in operation, have the ability to be left unattended by fire-fighting personnel. The wild and natural whipping action exhibited from a fire hose under high operating pressures is nullified with the present nozzle. The body of the nozzle is a hollow paraboloid attached to a coupler bearing assembly. The nozzle body is made from a resilient and durable material with concavo-convex surfaces with a plurality of ports emitting liquid in a radial 'Dandelion puff' pattern. Three of the four port groups have approximate angles which are arranged tangentially and acutely to the axis of rotation and flow. The fourth group has an approximate angle which is arranged acutely to the horizontal plane of the longitudinal axis of rotation and flow. The nozzle assembly may be transported, delivered, placed, propelled, launched, carried, or otherwise put in any mode, means, or fashion to a target to which a liquid needs to be provided or dispersed.</p> |
