Abstract
A sprinkler nozzle is described, having a hydrofoil member located on a lower surface near the nozzle exit aperture. As the water exits the nozzle, a portion of that water moves over the hydrofoil, causing it to be gently directed downwards with minimal turbulence. A portion of this water may be further directed by ramps extending from the face of the nozzle. Ultimately, the water is distributed to close-in areas of turf at about the same rate as other distances in the watering radius, eliminating “close-in” overwater that occurs in prior art nozzles. Additionally, by providing a less abrupt flow-directing feature than the prior art, the rate and therefore the force of the nearby watering flow is less (i.e., more gentle) than prior art nozzles.
