Irrigation nozzles are provided that irrigate a full circle coverage area with different maximum throw radiuses. The nozzle may include two bodies, one nested within the other, that acting together form the full circle coverage area. The two bodies collectively define an annular exit orifice with one of the bodies defining the inner radius and the other body defining the outer radius. A flow restrictable inlet may be used to adjust flow through the nozzle and to adjust the maximum throw radius. The nozzle may also include a flow reduction valve to reduce the throw radius from a maximum distance and may be adjusted by actuation of an outer wall of the nozzle. A deflector for use with an irrigation nozzle is also provided.

A sprinkler head includes a sprinkler body, a nozzle positioned within the sprinkler body, a fixed gear coupled with the sprinkler body, a wobbler cage supported on the sprinkler body, and a water deflector plate coupled with the wobbler cage and disposed downstream of the nozzle. A brake assembly is coupled with the water deflector plate for slowing a rotating and wobbling motion of the wobbler cage and the water deflector plate. The brake assembly includes a shaft extending through the water deflector plate and a brake gear disposed at an end of the shaft, where the brake gear is engageable with the fixed gear. Among other advantages, the design eliminates the use of large fixed strut framework that creates dry shadows in the water pattern.

A sprinkler device for delivering an irrigation liquid for gravity-based pivot or linear irrigation systems includes a support structure having a first portion with a nozzle defining a longitudinal axis for generating a jet of liquid, and a second portion with a baffle plate pivoted thereto and facing the nozzle. The second portion includes a drive system, which has a first magnet moving with a reciprocating oscillatory motion due to a negative pressure generated by the liquid that flows through the nozzle, and is configured to move the baffle plate along, and force it to pivot with a reciprocating oscillatory motion about the longitudinal axis through a predetermined angle, to thereby deliver the liquid over a sector area of the soil. A method of delivering an irrigation liquid for gravity-based pivot or linear irrigation systems that uses such a sprinkler device.

A sprinkler includes a body defining (a) a passage having an inlet and extending along a longitudinal axis and (b) an outlet fluidly coupled to the passage. The sprinkler includes a seal engaging a button and the body to fluidly seal the inlet from the outlet. A link and lever assembly includes a first lever and a second lever engaging the button. The first lever and the second lever each include (a) a leg positioned near a base end of the lever and extending outward from the longitudinal axis, the leg defining an engagement surface, (b) a head positioned near a tip end of the lever, and (c) a main body extending from the leg to the head. A fusible link limits movement of the heads. The engagement surfaces each engage a surface of the body to limit movement of the button along the longitudinal axis.

A sprinkler assembly includes a body defining an inlet, an outlet, and a fluid passage extending along a longitudinal axis between the inlet and the outlet. A guide pin aperture is defined by at least one of the body or a bushing coupled to the body. The sprinkler assembly further includes a deflector slidably coupled to the body. The deflector includes a deflector body coupled to a guide pin. The guide pin includes a shaft portion extending through the guide pin aperture and a shoulder that is wider than the shaft portion and configured to engage at least one of the body or the bushing to limit movement of the deflector body away from the body.

A shroud for a sprinkler head having a series of removable tabs to allow for configuring a shield-to-shield water distribution from the sprinkler head. The shield has removeable tabs of which allow for water to be sprayed past the shield. The shroud is utilized to configure the distribution of water from a sprinkler head so as, for example, to limit water distribution on unintended or undesired areas. Embodiments of the shroud can be configured to attach by a clip to a sprinkler head, by engagement with a weight threadingly engaged with the sprinkler head, by friction engagement with the sprinkler head, or by alternate attachment. The shroud can be configured in different embodiments to attach to a specific sprinkler head in the industry or configured to attach to different varieties of sprinkler head.

Various embodiments include a fogging sprayer nozzle that includes a nozzle base and an outer cap. The nozzle base includes an inner passage extending along an axial extent of the nozzle base. The inner passage may be configured to allow a first fluid to pass through the nozzle base from a proximal base aperture in a proximal end of the nozzle base to a distal base aperture in a distal end of the nozzle base. The nozzle base may include a plurality of fins radially extending outwardly and spiraling along the axial extent of the nozzle base. The outer cap includes an inner chamber configured to receive and surround at least a portion of the nozzle base seated therein. The outer cap includes a proximal cap aperture in a proximal end of the outer cap and a distal cap aperture in a distal end of the outer cap. The nozzle base may be received through the proximal cap aperture. A second fluid may be configured to flow inside the inner chamber and between the plurality of fins from the proximal cap aperture toward the distal cap aperture.

A sprinkler assembly with a nutating distribution plate that tilts and/or rotates upon water impinging the distribution plate. A deflector assembly includes the distribution plate and a base. A body of the sprinkler assembly includes a base retainer surface and a flanged bolt which combine to create a portion of a confinement structure. A portion of the deflector assembly is located within the confinement structure to limit a range of movement of the distribution plate. A nozzle subassembly includes a nozzle and retainer supporting a seal. The nozzle alone or in combination with the retainer can be removed from the sprinkler assembly. The sprinkler assembly can be disassembled and reassembled with minimal tools and effort for servicing. The distribution plate and the base can have mass properties optimized to improve sprinkler performance by reducing vibration, improving uniform water distribution, and reducing fine water droplet generation upon water stream impingement on the distribution plate.

What is disclosed is a sprinkler head having a nozzle configured for spraying a fluid, such as irrigation water, at a distribution disk. The distribution disk is configured to rotate on an upper axle. The upper axle is housed within an upper axle housing. The upper axle housing is configured to rotate about a lower axle. The dual axle provides for two different rotation axles of the distribution disk in operation. Preferably a speed control device can be positioned to control the speed of rotation of one axle or both axles.
