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