摘要： 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.

摘要： A sprinkler head includes a base adapted to be secured to a component supplying water under pressure; an arc adjustment ring rotatably mounted on the base; a nozzle and a stream deflector supported by an elongated stem carried by the base, the nozzle and the stream deflector cooperating to define an adjustable nozzle orifice; a water distribution plate secured to a shaft in the stem and located downstream of the nozzle; the stem and the nozzle axially movable relative to the base; and a drive train operatively connected between the arc adjustment ring and the nozzle to rotate the nozzle relative to the stream deflector to thereby adjust the nozzle orifice between a pair of limit positions. The stem is rotatable within the base upon over-rotation of the arc adjustment ring beyond either of the pair of limit positions. The sprinkler head also incorporates a throttle control memeber secured to an upstream end of the shaft such that rotation of the shaft causes the throttle control member to move axially relative to a flow restriction seat portion, to thereby adjust flow rate through the nozzle, the throttle control member engageable with the seat in a maximum restriction position; and means for permitting rotation of the throttle control member with the shaft upon over-rotation of the shaft.

摘要： A sprinkler head includes a base; an elongated stem having an inlet supported within the base; a nozzle and a stream deflector supported within the stem, the nozzle and stream deflector cooperating to define an arcuate orifice; a water distribution plate supported on one end of a shaft extending upwardly from the base, the water distribution plate located in axially spaced relationship to the nozzle and adapted to be impinged by a stream emitted from the nozzle. An externally threaded sleeve is fixed to an opposite end of the shaft; and an elastomeric throttle control member constructed with a smooth through-bore is engaged over the externally threaded sleeve to self-tap along the previously smooth bore. The throttle member is prevented from rotating such that rotation of the shaft causes the throttle control member to move axially relative to a flow restriction portion in the inlet, to thereby adjust flow rate through the stem and the nozzle.

摘要： A sprinkler includes a body having an inlet and an outlet, an adapter having an end face secured to the inlet, and a stream distributor plate located downstream of the outlet. A quick change nozzle is slidably received on the adapter, the nozzle having a nozzle inlet at one end and a discharge orifice located at an opposite end adjacent the outlet. The nozzle also includes an externally visible identification band adjacent the inlet at an interface between the adapter and the body, as well as an annular, radial flange proximate to the opposite end. The nozzle is also held in a horizontally extending clip, the clip projecting laterally away from the body and holding a second alternatively usable nozzle laterally adjacent the first nozzle:, the clip being reversible such that the first and second nozzles are selectively mountable on the adapter.

摘要： A nutating sprinkler includes a body portion having a nozzle at one end and a spray plate supported thereon at an opposite end downstream of the nozzle. The spray plate has a plurality of stream distributing grooves formed on one side thereof configured to cause the spray plate to rotate when struck by a stream emitted from the nozzle. The spray plate also includes a flexible connector coupling the spray plate to a free end of a first rigid shaft seated in a housing at the opposite end, such that the spray plate is caused to wobble about a common center of motion as it rotates.

摘要： A pop-up rotary sprinkler includes a sprinkler body, a rotatable distributor and nozzle assembly mounted in the sprinkler body for movement between inoperative retracted and operative extended positions in response to fluid pressure within the sprinkler body. The rotatable distributor has a plurality of water distribution grooves and is supported at an upper end portion of a shaft, while the nozzle assembly surrounds a lower end portion of the shaft. The nozzle assembly includes a discharge orifice having a peripheral surface at least a part of which is defined by a peripheral surface of the shaft, and a deflector is mounted on the shaft downstream of the discharge orifice and upstream of the distributing grooves, and is adapted to direct water emanating from the discharge orifice onto the distributing grooves so as to avoid direct impingement on a seal located at the distributor-shaft interface.
