Abstract: A sprinkler head includes a base; an arc adjustment ring; a nozzle and a stream deflector supported by an elongated stem carried by the base, the nozzle and the stream deflector cooperating to define an adjustable nozzle orifice; a water distribution plate secured to a shaft and located downstream of the nozzle; and a drive train operatively connected between the arc adjustment ring and the nozzle to rotate the nozzle relative to the stream deflector to adjust the nozzle orifice between limit positions. The stem is rotatable within the base upon over-rotation of the arc adjustment ring beyond the limit positions. The sprinkler head also incorporates a throttle control member movable axially relative to a flow restriction seat, to thereby adjust flow rate through the nozzle, and means for permitting rotation of the throttle control member with the shaft upon over-rotation of the shaft.

Abstract: A sprinkler head includes a base adapted to be secured to a component supplying water under pressure; an arc adjustment ring rotatably mounted on the base; a nozzle and a stream deflector supported by an elongated stem carried by the base, the nozzle and the stream deflector cooperating to define an adjustable nozzle orifice; a water distribution plate secured to a shaft in the stem and located downstream of the nozzle; the stem and the nozzle axially movable relative to the base; and a drive train operatively connected between the arc adjustment ring and the nozzle to rotate the nozzle relative to the stream deflector to thereby adjust the nozzle orifice between a pair of limit positions. The stem is rotatable within the base upon over-rotation of the arc adjustment ring beyond either of the pair of limit positions. The sprinkler head also incorporates a throttle control member secured to an upstream end of the shaft such that rotation of the shaft causes the throttle control member to move axially relative to a flow restriction seat portion, to thereby adjust flow rate through the nozzle, the throttle control member engageable with the seat in a maximum restriction position; and means for permitting rotation of the throttle control member with the shaft upon over-rotation of the shaft.
