Abstract:
1. 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 plurality of discharge streams emitted from said nozzle body and to cause the water distribution plate to rotate when struck by the stream, said nozzle body having an outlet defined by an edge; a stream deflector comprising a center hub extending axially along said shaft, said stream deflector supported within said sprinkler body with the center hub extending through the outlet of the nozzle body such that the center hub of the stream deflector is at least partially radially surrounded by the edge of said nozzle body to allow water to pass between the center hub and the edge; wherein said stream deflector comprises a pair of vertical ribs and a surface that cooperates with said edge to define a first discharge orifice section, said stream deflector further comprising a pair of slots that cooperates with said edge to define second and third discharge orifice sections disposed on either side of said first discharge orifice section, and wherein the discharge orifice sections are configured to disperse water passing therethrough in the plurality of respective discharge streams to impinge on said water distribution plate to produce a substantially rectangular wetted pattern area.
