Abstract

An improved nozzle assembly for use with a sprinkler body. The nozzle assembly has a nozzle body having a nozzle insert bore and defining a fluid flow path through the nozzle assembly. A nozzle insert is positioned in the nozzle body and retained within the nozzle assembly. The nozzle insert is rotatable between operating positions. In some embodiments, a spring biased detent and detent notches index the nozzle insert at one of a series of operating positions. The nozzle insert is rotatable between the series of operational positions including the IN (or insertion) position, the RUN position, the OFF position, the FLUSH position, and the LINE FLUSH position. In an alternate embodiments the nozzle insert has detents on a circumference of the nozzle insert. A magnet is positioned in or attached to the nozzle insert. A second magnet is positioned in or attached to the body of the nozzle assembly. The detents are configured to align with detent notches in a faceplate of the nozzle assembly body. When the detents are aligned with the detent notches, the attractive force between the two magnets retains the nozzle insert in one of the operating positions in the nozzle insert bore.
