Two-axis full-circle sprinkler with bent, rotating nozzle
First Claim
1. A sprinkler device comprising a sprinkler body having a longitudinal center axis defining a first axis, an inlet at one end and an outlet at an opposite end;
- a rotatable nozzle mounted within said body and defining a first flow path lying on said longitudinal center axis and a second flow path terminating at a discharge orifice offset from said longitudinal center axis;
a rotor plate supported on a shaft fixed to said nozzle for orbital motion about said longitudinal center axis and for rotation about a second axis offset from said longitudinal center axis, said rotor plate having grooves formed therein shaped to cause said rotor plate to rotate about said second axis when a stream emitted from said nozzle impinges on said plate, and wherein said nozzle is thereby caused to rotate about said first axis, wherein said second axis is substantially parallel to said first axis.

Abstract
A sprinkler device includes a sprinkler body having a longitudinal center axis, an inlet at one end and an outlet at an opposite end. A rotatable nozzle is supported within the body and defines a first flow path lying on the longitudinal center axis and a second flow path terminating at a discharge orifice offset from the longitudinal center axis. A rotor plate is supported on the nozzle for orbital motion about the longitudinal center axis and for rotation about a second axis offset from the longitudinal center axis. The rotor plate has a plurality of grooves formed therein, and arranged to cause the rotor plate to rotate about the second axis when a stream emitted from the nozzle impinges on the plate, such that the nozzle assembly is caused to rotate about the first axis.

12. A sprinkler device comprising:
-
a body portion having a fluid passage therethrough defining a first longitudinal axis; a nozzle component mounted for rotation in said body portion about said first longitudinal axis, said nozzle component having a discharge orifice radially offset from said first longitudinal axis; and a rotor plate supported downstream of said nozzle component for rotation about a second axis offset from said first longitudinal axis, and for orbital motion about said first longitudinal axis, said rotor plate having a plurality of grooves therein and located such that a stream emitted from said discharge orifice impinges on said grooves, wherein said second axis is substantially parallel to said first longitudinal axis. - View Dependent Claims (13, 14, 15, 16, 17, 18)
