Oscillating nozzle sprinkler with integrated adjustable arc, precipitation rate, flow rate, and range of coverage

摘要

An oscillating nozzle sprinkler for directing an adjustable flow of water therefrom at adjustable desired range and arc of coverage and at a pre-settable precipitation rate. The desired flow rate or precipitation rate for a particular arc of coverage can be selected and the flow will then be automatically varied as the arc of sprinkler oscillation is adjusted to maintain the precipitation rate that was set. The nozzle discharge range is adjustable from the top with integrated flow control to automatically maintain the precipitation rate that was set constant as the range is changed for a smaller area of coverage due to the reduced range.
