摘要
An improved fluid spray head for sprinkler apparatus is disclosed adjustable both as to the flow rate of fluid to the discharge orifices and the precipation rate over the ground area sprayed, and particularly adapted to spray a specifically shaped non-circular area. The spray head has a plurality of circumferentially-spaced discharge orifices having cross-sectional areas equally proportional to the square of the distance that their respective spray streams are desired to travel whereby the perimeter of the ground area sprayed defines the preselected shape and receives a substantially uniform coverage of fluid.
