    摘要: An irrigation sprinkler includes an outer case and a riser extensible from the outer case by water pressure and normally in a retracted position. A nozzle is rotatably mounted at an upper end of the riser. A turbine is mounted in the riser for rotation by water entering a lower end of the riser. A gear train reduction is mounted in the riser. A gear driven coupling mechanism mounted in the riser couples the gear train reduction and the nozzle. A pressure regulator valve is located inside a nozzle turret of the sprinkler and includes a valve member that is pivotably mounted between the gear train reduction and the nozzle.

    摘要: A sprinkler includes a stream nozzle with a plurality of circumferentially spaced, radially extending stream forming ports. A non-rotating arc adjustment sleeve is mounted for axial movement relative to the stream nozzle to selectively block the stream forming ports to vary an arc of coverage of a plurality of streams of water ejected from the stream forming ports.
