Abstract:
1. A rotary sprinkler comprising: a housing with an inlet for receiving fluid for irrigation, the housing having a longitudinal axis; a nozzle defining an outlet with a variable geometry for projecting irrigation fluid from the sprinkler, the nozzle mounted for rotation relative to the housing; a drive mechanism for rotating the nozzle in a reversible arc of rotation between a pair of stops defining ends of the reversible arc of rotation; an arc adjustment mechanism coupled to at least one of the stops, the arc adjustment mechanism arranged and configured upon adjustment thereof to increase or decrease the arcuate distance between the pair of stops to increase or decrease the arc of rotation of the nozzle; and a flow control member arranged and configured to shift in an axial direction relative to the nozzle to vary the geometry of the outlet, the flow control member operably coupled to the arc adjustment mechanism such that adjustment of the at least one stop is operable to shift the flow control member in the axial direction to change the geometry of the outlet to adjust a flow rate through the outlet proportional to the arc of rotation.
