Abstract: A long throw Pop-Up Irrigation Nozzle assembly has no oscillating or rotating parts and includes a cylindrical body having a fluid inlet and a sidewall defining at least one fluidic circuit configured to generate a selected spray pattern when irrigation fluid flows through the body. In order to throw long distance, droplet velocity, droplet size and droplet initial aim angle determine the throw to provide a low precipitation rate (“PR”) for fluidic sprays. The nozzle assembly and method of the present invention achieve a PR of 1 in/hr or less and good spray distribution with a scheduling coefficient (“SC”) of about 1.5 without utilizing any moving components to provide a significantly more cost effective nozzle assembly, as compared to prior art rotator nozzles.

Abstract: A sprinkler assembly includes a sprinkler housing including at least one fluidic- circuit-receiving port carrying a fluidic insert configured to receive irrigation fluid and project the irrigation fluid in a desired spray pattern. The fluidic insert is held precisely in place by a retention ring adapted for insertion into the housing's interior lumen to provide a snap or friction fit within the housing while engaging and retaining the fluidic insert against impact forces from inrushing fluid surge. The retention ring fits entirely within the sprinkler assembly's housing or package, and is economically molded as a one-piece component, and does not have any effect on external appearance of the sprinkler assembly or any adverse effect on the fluidic insert's spray pattern.
