A rotary sprinkler including a rotatable nozzle turret with automatic matched precipitation to an arc of rotation, a nozzle purge feature, and/or a flow shut off valve coupled to a variable flow nozzle outlet.

Arc adjustable rotary sprinkler having full-circle operation and automatic matched precipitation

A magnetically driven irrigation sprinkler is disclosed with a magnetic drive mechanism for rotating a fluid outlet relative to a fluid inlet. In one form, the drive mechanism includes a permanently polarized magnet and an electromagnet.

Hold-up tool for pop-up sprinkler risers

An improved gear drive sprinkler has a pop-up spray head adapted for adjustable part-circle or full circle operation to deliver irrigation water over a selected terrain area. The sprinkler includes a pop-up riser; a gear drive transmission mounted within the riser includes a water-driven turbine for rotatably driving a speed reduction gear train, which in turn rotatably drives the spray head. A reverse assembly includes an upper trip unit defining an individually adjustable pair of end trip stops, and a lower shift mechanism including a shiftable director plate having first and second sets of angularly oriented jet nozzles for respective alignment with turbine jet ports for respectively driving the water-driven turbine and the gear train in a forward-drive or a reverse-drive direction. The upper trip is coupled to the director plate by an elongated trip rod which shifts the director plate between forward-drive and reverse drive positions. An adjustment cam can be manipulated to disable at least one of the end trip stops to permit spray head rotation through continuous full circle revolutions.
