Adjustable arc, adjustable flow rate sprinkler

摘要

A sprinkler head includes a base having a lower end adapted for attachment to a sprinkler system component; an elongated stem supported within the base; a nozzle and a fixed deflector supported within the stem, the nozzle and deflector cooperating to define an adjustable arcuate orifice. A water distribution plate is supported on a shaft extending upwardly from the stem and has a plurality of water distribution grooves located in axially spaced relationship to the nozzle. An arc adjustment ring is rotatably mounted on the base and is operatively connectable with the nozzle for rotating the nozzle relative to the stem for adjustment of the arcuate discharge orifice. A throttle member is secured to the upstream end of the shaft such that rotation of the shaft causes the throttle to move relative to a portion of the stem, to thereby adjust flow rate through the nozzle.
