Adjustable arc, adjustable flow rate sprinkler

A sprinkler head comprising a base;

• an elongated stem having an inlet supported within said base;
• a nozzle and a stream deflector supported within said base, said nozzle having a first moveable edge and deflector having a second normally fixed edge cooperating to define an adjustable arcuate discharge orifice;
• a water distribution plate supported on a shaft extending upwardly from said base, said water distribution plate having a plurality of water distribution grooves therein located in axially spaced relationship to said nozzle and adapted to be impinged by a stream emitted from the nozzle;
• an arc adjustment ring rotatably mounted on said base, said arc adjustment ring operatively connectable with said nozzle for rotating said nozzle and first movable edge relative to said stem and second normally fixed edge for adjustment of said arcuate discharge orifice;
• means operable through said arc adjustment ring for adjusting said second normally fixed edge to reorient said sprinkling pattern;
• an externally threaded sleeve fixed to said shaft;
• and
• an elastomeric throttle control member constructed with a smooth through-bore, engaged over said externally threaded sleeve but prevented from rotating such that rotation of said shaft causes said throttle control member to move axially relative to a flow restriction portion in said inlet, to thereby adjust flow rate through said stem and said nozzle.

• a nozzle supported within the stem and adapted to emit a stream;
• a shaft extending through said base, one end of said shaft having an externally threaded sleeve thereon;
• and
• an elastomeric throttle control member constructed with a smooth through-bore, engaged over said externally threaded sleeve but prevented from rotating such that rotation of said shaft causes said throttle control member to move axially relative to a flow restriction portion in said inlet, to thereby adjust flow rate through said stem and said nozzle.

• an elongated stem having an inlet supported within the base;
• a nozzle supported within the stem and adapted to emit a stream;
• a shaft extending through said base;
• and
• an elastomeric throttle control member having at least one rotation prevention tab projecting therefrom, said throttle control member operatively associated with said shaft such that rotation of said shaft causes said throttle control member to move axially relative to said shaft and to a flow restriction portion in said inlet, to thereby adjust flow rate through said stem and said nozzle.
