摘要： In one aspect, a sprinkler is provided having a nozzle, a deflector that receives fluid flow from the nozzle, and a friction or viscous brake assembly that controls rotation of a deflector. The friction or viscous brake assembly is releasably connected to the frame in order to enhance serviceability of the sprinkler. In another aspect, a sprinkler is provided having a frame, a deflector rotatably connected to the frame, a nozzle, and a nozzle socket of the frame. The nozzle and nozzle socket have interlocking portions that releasably connect the nozzle to the frame. The nozzle may be easily removed for servicing. Further, the nozzle socket can be configured to receive a plurality of nozzles having different flow characteristics. A nozzle can be selected and utilized with the sprinkler according to the desired application for the sprinkler.

摘要： A rotational speed control device includes a housing containing a viscous fluid and a shaft disposed in the housing and rotatable relative to the housing. A rotor may be movable axially on the shaft depending on the rotating speed of the shaft. The rotor is biased in a low torque direction. A braking torque between the rotor and the housing is varied according to an axial position of the rotor on the shaft.

摘要： A rotational speed control device includes a housing containing a viscous fluid, a shaft disposed in the housing and rotatable relative to the housing, a hub assembly secured to the shaft for rotation with the shaft, and a rotor coupled with the shaft by a frictional engagement with the hub assembly. A spring is disposed in the housing and acts on the rotor to bias the rotor axially on the shaft in a low torque direction. A braking torque between the rotor and the housing is varied according to an axial position of the rotor on the shaft.

摘要： A revolving sprinkler comprises a rotatable turret assembly revolving around a rotation axis and formed with mouthpiece(s) suited to sprinkle liquid under pressure. The revolving sprinkler accommodates exchangeable mouthpieces with different throughputs-nozzle to rotation axis distance relationships, without changing a rotation velocity of the turret assembly.

摘要： A water distribution plate and diffuser plate assembly for distributing a stream emitted from a sprinkler nozzle includes: a nonrotatable shaft (14) having one end attached to a sprinkler component and an opposite end supporting first and second plates in axially spaced relationship for rotation about the shaft independent of one another. The first plate is axially adjacent the nozzle and formed with plural water distribution grooves (24) shaped and arranged to divide a single primary stream emitted from the nozzle into a plurality of secondary streams. The second plate is downstream of the first plate and formed with plural diffuser elements (30) arranged to be struck by at least some of the secondary streams exiting the first plate. The speed of rotation of one or both plates is slowed by viscous damping.

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 member 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 pop-up, rotating stream sprinkler device includes an outer housing having a first longitudinal axis, an inlet end adapted for connection to a source of liquid under pressure, a first inner housing telescopically mounted within the outer housing for movement between retracted and extended positions, and having a second longitudinal axis coincident with the first longitudinal axis, and an outlet end provided with a first arcuate slot adapted to discharge a stream of liquid under pressure. A non-rotatable shaft supports at one end thereof a substantially hollow distributor for rotation thereon downstream of the outlet. The other end of the shaft is fixedly mounted in the first inner housing, and the hollow distributor includes an interior chamber enclosing a brake assembly for retarding the rotation of the distributor. A nozzle disk is removably and rotatably secured to the first inner housing and provided with at least one discharge orifice, so that the nozzle is rotatable to align any part of the at least one discharge orifice with the arcuate slot.
