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.
