Patent ID: 8628027

Claim:
An oscillating sprinkler with adjustable arc of coverage comprising: a nozzle; a nozzle drive mechanism operable to drive the nozzle through a set arc of coverage; an arc set mechanism coupled to the nozzle drive mechanism and operable to adjust the set arc of coverage for the nozzle drive mechanism; and a flow control mechanism formed as part of the nozzle and configured and operable to vary a nozzle flow area through which water flows through the nozzle and out of the sprinkler, the flow control mechanism coupled to the arc set mechanism such that the flow area is adjusted with the arc of coverage, the flow control mechanism further comprising: a flow valve element rotatably mounted as a part of the nozzle and configured such that the flow valve element itself increases the flow area when rotated in a first direction and decreases the flow area when rotated in a second direction opposite the first direction.
