Two piece variable stator for sprinkler nozzle flow control

摘要: A variable stator for use in a sprinkler head has two piece housing which includes flexible inner sidewalls overlying spaced apertures an outer sidewall. The plurality of drive ports pass controlled portion the fluid flow against impeller that is part mechanism rotating nozzle head. flex inwardly as function around relative to selectively open keep rate rotation relatively constant. By locating within stator, upstream remaining and through apertures, wear on minimized. In addition, turbulence minimized further reduce increased control.
