Abstract
A method and apparatus for enhancing the distribution of water from an irrigation sprinkler is provided and includes a nozzle disposed at the end of a discharge tube on the sprinkler, which nozzle includes a frusto-pyramidal passage leading to a polygonal nozzle outlet, thereby generating a substantial secondary flow within the nozzle which provides the desired controlled fall-out of water over the entire range of the stream ejected by the sprinkler.
