Abstract
An adjustable arc sprinkler includes first and second adjacent members that define a nozzle orifice. The first member can be connected to the end of a riser and defines a flow path leading to the nozzle orifice. The second member is rotatable relative to the first member to select a desired size of an adjustable arc fan-shaped water spray pattern when water travels through the flow path and is ejected from the nozzle orifice. A pair of features formed on the first and second members are configured to enhance a distribution of water at the edges of the water spray pattern.
Claims10
A sprinkler, comprising:
- upper and lower generally cylindrical members having opposing peripheral helical edges defining a nozzle orifice, the upper member being rotatable relative to the lower member to select a desired arc size of a fan-shaped water spray pattern ejected from the nozzle orifice, the upper member having a swept cut that forms an upward taper of a final highest segment of the peripheral helical edge of the upper member, and the lower member having a vertically extending wall that connects a pair of terminal ends of the lower peripheral helical edge, the swept cut and the wall being configured to increase the amount of water received at a pair of edges of the fan-shaped water spray pattern.
