摘要： 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.

摘要： A packaging/inspection system is provided for a nozzle pivot package including a collection of nozzles in various nozzle sizes. The packaging/inspection system includes a shelf assembly with a plurality of compartments, an operator load track, a verification section downstream of the operator load track, a marking section downstream of the verification section, and an operator unload track downstream of the marking section. Each compartment may store nozzles of a specific nozzle size. Features of the shelf assembly alert the operator as to which compartment should be accessed and how many nozzles from the compartment are required.

摘要： A sprinkler body for a rotating sprinkler includes a base securable to a source of water under pressure, a plurality of support struts connected to and extending from the base, and a deflector plate support connected to the plurality of support struts and disposed spaced from the base by the support struts. At least one of the plurality of support struts is wedge-shaped with an inward-facing apex. The support struts are configured to create a void in the water spray pattern away from a center pivot pipe and to direct the water spray downward to limit the effect of wind on the spray pattern.

摘要： 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.

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 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.

摘要： A sprinkler and side-loading nozzle insert assembly includes a sprinkler body provided with a flow passage and a nozzle insert seated in a complementary recess in said sprinkler body. The nozzle insert is rotatable to plural operating positions and it includes an elongated, substantially cylindrical insert body having an insert axis about which the nozzle insert rotates. A nozzle bore extends through the insert body on an axis transverse to the insert axis and alignable with the flow passage in one of the plural operating positions. A forward end face is provided with a turning knob and plural index tabs extending radially from the insert body at circumferentially-spaced locations proximate the forward end face. The index tabs are adapted to engage respective index notches in the sprinkler body as the insert body is rotated to the plural operating positions.

摘要： An automatic reversible arc assembly for a sprinkler includes a pair of primary stop members circumferentially spaced from each other by a first amount, and a pair of secondary stop members circumferentially spaced from each other by a second amount, different from the first amount. The primary stop members and the secondary stop members are coupled together and define a pivot assembly pivotable between a first position and a second position. A timer module cooperable with the pivot assembly is configured to hold the pivot assembly in the first position for a selectable period of time, after which the timer module enables the pivot assembly to pivot to the second position. The primary stop members are active in the first position, and the secondary stop members are active in the second position.
