ABSTRACT:
A turbine for a sprinkler is disclosed for self-governing its rotational velocity. As a rate of fluid through the sprinkler increases, particularly when air is used to flush the sprinkler system, a portion of the turbine shifts outwardly so as to decrease alignment of vanes located thereon with directed water streams for controlling the rotation of the turbine.
