Rotary sprinkler stream interrupter with enhanced emitting stream

A sprinkler comprising a sprinkler body having a center axis and including a nozzle adapted to issue a vertical stream along said center axis, and an associated rotor plate for redirecting the stream in a substantially radial direction, substantially perpendicular to said axis while rotating about said center axis;

• a stream interrupter mounted loosely for eccentric rotation about said center axis, said stream interrupter including an annular ring provided with a plurality of stream deflector fingers, said stream interrupter being driven directly by said stream impinging on said plurality of stream deflector fingers, and wherein said rotor plate is formed with a groove configured to receive the vertical stream and to redirect the stream in said radial direction while also causing the rotor plate to rotate about said center axis, and further wherein said groove is profiled to cause the stream to issue from the rotor plate with a primary component and a secondary component diverging from said primary component, and further wherein said primary and secondary stream components are arranged such that the secondary stream engages a respective one of said stream interrupter vanes before the primary stream, and is deflected back into the primary stream to form a third concentrated stream.

A sprinkler comprising a sprinkler body mounting a nozzle and a cap assembly including a hub supporting a rotor plate for rotation about an axis which passes through said nozzle;

• said rotor plate having a compound groove formed therein for receiving a stream emitted from said nozzle and for redirecting the stream substantially radially outwardly in two discrete stream portions;
• and a stream interrupter loosely mounted for eccentric rotation about said hub, said stream interrupter including an annular ring with a plurality of vanes depending therefrom and arranged to be successively struck by said stream portions exiting the compound groove such that said two discrete stream portions are combined to form a third concentrated stream.

A sprinkler having a nozzle for emitting a stream to atmosphere and including a rotor plate having a groove configured to rotate the stream and to direct the stream in a substantially radially outward direction;

• a relatively loosely mounted annular stream interrupter surrounding said nozzle and having a plurality of stream interrupter vanes arranged to be struck by the stream, wherein said interrupter vanes have profiles which cause said interrupter to move rotationally in an eccentric manner when struck by the stream, and further wherein said groove is further configured so that said stream is split into a primary component and a secondary generally parallel component prior to striking said interrupter, wherein said groove is configured so that the secondary stream engages a respective one of said stream interrupter vanes before the primary stream, and is deflected back into the primary stream to form a third concentrated stream.
