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.

Serviceable sprinkler with nutating distribution plate and asymmetrical water channels

A sprinkler assembly can include a water inlet and a nozzle assembly. The nozzle assembly can include a nozzle tube having a nozzle positioned at the downstream end of the nozzle tube. The sprinkler assembly can include a user replaceable wear disc at least partially surrounding the nozzle tube. A deflector assembly can be connected to the nozzle assembly and can include a distribution plate positioned downstream of the nozzle and configured to deflect water from the nozzle. The deflector assembly can include a cage having one or more arms connected to the distribution plate and extending from the distribution plate toward upstream end of the nozzle tube. The deflector assembly can include an upstream collar portion connected to the at least one arm and having one or more load surfaces configured to contact the wear disc, wherein the wear disc is configured to bear at least a majority of a weight of the deflector assembly.

A weight for attaching to a sprinkler is disclosed. The weight includes a connector having a passageway for water to flow between a first end and a second end. The first end includes a first coupling. The second end includes an outer surface and an inner surface. The outer surface includes a second coupling and the inner surface includes a third coupling. The connector supports a shell having a chamber. The chamber allows a user to add weight to or subtract weight from the shell. In a first aspect, the weight can be attach in multiple orientations to the same sprinkler. In a second aspect, the weight can be attached to a plurality of sprinklers that have different designs. In either aspect, the weight is considered universal.

An irrigation sprinkler head has an auxiliary nozzle carrier having a nozzle attached to each end thereof. Each nozzle is held on one end of the flexible nozzle carrier. One end of the nozzle carrier holding a nozzle is attached to the sprinkler head to operatively attach the nozzle to the outlet of the sprinkler head while the other end extends from the side of the sprinkler head. The nozzles are rapidly exchanged on the sprinkler head by disconnecting the nozzle carrier and nozzle from the sprinkler head and connecting the other end of the nozzle carrier and nozzle to the sprinkler head without removing either nozzle from the carrier and without the use of tools. The nozzle carrier is flexible and angled between the nozzle holding ends so that the nozzle carrier can flex between the ends thereof to absorb impact without damage when used below a crop line.

Flexible auxiliary nozzle carrier

A pressure regulator seat assembly is disclosed. In a particular embodiment, the assembly includes a chamber, a tapered flange projecting from an upstream edge of the chamber into a flow path of the assembly, where a proximate end of the flange attached to the chamber is tapered continuously to its distal end into the flow path. In addition, the assembly includes a throttling stem seat disposed on a lower surface of the flange and a plurality of support ribs adapted to support the flange, where the plurality of ribs is spaced about one half side of the chamber. The assembly may also include a complementary base adapted to mount to the chamber about a downstream edge of the chamber to form the assembly.

An irrigation sprinkler apparatus has a rapid change nozzle which allows the changing of a nozzle without the use of tools or any disassemble of the sprinkler head. The rapid change nozzle slides into a window in the side of the sprinkler head and latches into place.

Quick change nozzle

The present invention relates to an irrigation sprinkler head having a removable weighted collar thereon. The sprinkler head has a tapered water inlet for wedging a weighted collar having a matching tapered opening therethrough.

A riser support apparatus and method for supporting a riser pipe, having a sprinkler head thereon, on a nursery wire frame table. A riser support member and a locking member are attached together onto the nursery wire table so that a riser pipe can be attached to one side and a water supply pipe line to the other side thereof.

Riser support for nursery wire table

A mister nozzle apparatus has a check valve incorporated therein to shut off the water passing through the misting nozzle to prevent draining of the water from the misting water supply pipes. The check valve has a resilient membrane valve element which opens and closes responsive to water pressure to block or open the nozzle inlet. The check valve is vented to atmosphere through a vent located in the housing between the resilient membrane and the nozzle misting outlet.
