ABSTRACT:
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.
In a preferred embodiment, the spray head includes an inner tubular member which telescopes within an outer tubular member to provide the simultaneous adjustment of the size of the discharge orifices and wherein the inner tubular member is made radially thinner so as to be more pressure expandable under fluid pressure to thereby tighten the fluid seal between the inner tubular member and the outer tubular member.
Methods for constructing and operating a fluid spray head adapted to spraying a specific pattern or shaped area are also disclosed.
