Abstract: 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.

Abstract: A rotational speed control device maintains a shaft rotation speed. The device includes a housing containing a viscous fluid and a shaft disposed in the housing and rotatable relative to the housing. A rotor is coupled with the shaft for rotation in the viscous fluid. In one arrangement, the rotor is axially displaceable along the shaft between a low-shear position and a high-shear position. A spring mechanism is disposed in the housing and biases the rotor toward the low-shear position. In another arrangement, the rotor may be designed to cooperate with the housing or other nonrotating features within the housing to vary a shear gap according to radially expanding components of the rotor. The rotor, housing and spring mechanism can be designed to cooperate to create large changes in braking torque in response to small changes in shaft rotational speed. This allows the rotation speed to be controlled within a relatively narrow range.
Abstract translation: 旋转速度控制装置保持轴的转速。 该装置包括容纳粘性流体的壳体和设置在壳体中并相对于壳体可旋转的轴。 转子与轴联接以在粘性流体中旋转。 在一种布置中，转子在低剪切位置和高剪切位置之间沿着轴可轴向移动。 弹簧机构设置在壳体中，并将转子朝向低剪切位置偏压。 在另一种布置中，转子可以被设计成与外壳内的壳体或其它非旋转特征配合，以根据转子的径向扩张的部件改变剪切间隙。 转子，壳体和弹簧机构可以设计成协调，以响应于轴转速的小变化而产生制动转矩的大的变化。 这允许将旋转速度控制在相对较窄的范围内。

Abstract: A clip for holding a pair of nozzle inserts for use with an irrigation sprinkler includes at least two flexible attachment arms, each attachment arm provided with an elongated slot and a retention shoulder on an inside surface thereof, adjacent the elongated slot. Each attachment arm is adapted to be received in an opening in a respective nozzle insert and retained therein by the retention shoulder. A related tool includes a pair of gripper arms and a respective pair of jaws extending from the gripper arms, pivotally secured to one another. One jaw is formed with a pair of parallel prongs, and the other jaw is formed with a flat head projecting toward the pair of prongs. The jaws are adapted to engage the nozzle insert and disengage the retention shoulder to permit removal of the nozzle insert from the clip.

Abstract: A rigid mount orbitor sprinkler assembly incorporates a deflector plate configuration that is configured for both spinning/rotating motion as well as orbital or wobbling motion around the center of a spool assembly. The sprinkler incorporates structure to reduce drool that may fall in a concentrated area below the sprinkler and to prevent debris from sandy water or the like from accelerating sprinkler component wear. With reduced vibration, the assembly may be rigidly mounted on a center pivot or other supporting structure while achieving the advantages associated with wobbling and rotating sprinkler assemblies.

Abstract: A spool and wobbler assembly for a sprinkler includes a spool section with facing spool flanges on opposite sides of a spool core, where at least one of the spool flanges includes a circumferential rolling ledge. A wobbler cage including a wobbler ring is supported on the spool section, and a water deflector plate is coupled with the wobbler cage. An underside of the wobbler ring is provided with a circumferential rolling surface that engages the circumferential rolling ledge of the at least one spool flange. The rolling surface and rolling ledge provide for smoother orbital motion of the deflector plate.
