Abstract
A rotary sprinkler comprising a sprinkler body supporting a nozzle body and a water distribution plate supported on a shaft downstream of said nozzle body, said water distribution plate provided with a plurality of grooves shaped to redirect a stream emitted from said nozzle body and to cause the water distribution plate to rotate when struck by the stream; a stream deflector supported within said sprinkler body and surrounding said nozzle body; wherein said nozzle body and said stream deflector cooperate to produce a substantially rectangular wetted pattern area.
Claims23
A rotary sprinkler comprising a sprinkler body supporting a nozzle body and a water distribution plate supported on a shaft downstream of said nozzle body, said water distribution plate provided with a plurality of grooves shaped to redirect a stream emitted from said nozzle body and to cause the water distribution plate to rotate when struck by the stream, said nozzle body having an edge partially defining plural discharge orifices;
- a stream deflector supported within said sprinkler body and surrounded by said nozzle body;
- wherein said stream deflector is configured to cooperate with said edge to produce a substantially rectangular pattern.
A rotary sprinkler comprising a sprinkler body supporting a nozzle body and a water distribution plate supported on a shaft downstream of said nozzle body, said water distribution plate provided with a plurality of grooves shaped to redirect a stream emitted from said nozzle body and to cause the water distribution plate to rotate when struck by the stream, said nozzle body having an arcuate edge partially defining plural discharge orifices;
- and means for shaping a stream emitted from said nozzle body to produce a rectangular pattern.
A deflector for a sprinkler having a nozzle body formed with an arcuate edge that partially defines plural discharge orifices, the deflector comprising a center hub extending upwardly through an annular ring closed at an upper end thereof by a substantially horizontal surface, said center hub having an arcuate stream-engaging surface at an upper end thereof adapted to cooperate with the arcuate edge of the nozzle to form said plural discharge orifices;
- a pair of vertical, arcuately spaced ribs on said center hub extending upwardly from said horizontal surface for partially defining a first of said plural discharge orifices;
- an upstanding tab proximate one of said pair of ribs such that said one of said pair of ribs and said upstanding tab partially define a second of said plural discharge orifices, and wherein the outer of said pair of ribs partially defines a third of said plural discharge orifices;
- a first substantially arcuate slot formed in said horizontal surface between said one of said pair of ribs and said upstanding tab, and a second substantially arcuate slot formed in said horizontal surface adjacent the other of said pair of tabs;
- and at least one flow port formed in said horizontal surface between said pair of ribs.
A rotary sprinkler comprising a sprinkler body supporting a nozzle body and a water distribution plate supported on a shaft downstream of said nozzle body, said water distribution plate provided with a plurality of grooves shaped to redirect a stream emitted from said nozzle body and to cause the water distribution plate to rotate when struck by the stream, said nozzle body having an edge partially defining plural discharge orifices;
- a stream deflector supported within said sprinkler body and surrounded by said nozzle body;
- wherein said stream deflector is configured to cooperate with said edge to produce a substantially rectangular pattern, said deflector provided at least one port for restricting flow to one of said plural discharge orifices.
