A turbine rotor, e.g., for a drive turbine of a rotary atomizer, is disclosed having a rotatably supported turbine shaft with the potential for mounting an atomizer wheel, and having at least one drive turbine wheel having a plurality of turbine blades. The turbine blades of the drive turbine wheel may be impinged on during operation by a drive fluid in order to drive the turbine rotor. The drive turbine wheel may be designed for the drive fluid to axially impinge on the turbine blades. A complete drive turbine having such a turbine rotor is also disclosed, as well as a complete rotary atomizer and individual exemplary components of the drive turbine.

In one aspect, a sprinkler is provided having a nozzle, a deflector that receives fluid flow from the nozzle, and a friction brake assembly that controls rotation of a deflector. The friction 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.

A sprinkler nozzle for a sprinkler positioned at a distal end of a center pivot irrigation system is cooperable with a deflector plate of the sprinkler and includes a nozzle opening that is configured to distribute water back under a pivot pipe of the center pivot irrigation system to supplement a deficit of water from the sprinklers mounted along the pivot pipe

A nozzle assembly for discharging high-pressure liquid. The nozzle assembly includes a housing body and a nozzle shaft rotatably mounted therein. A nozzle head is coupled to the nozzle shaft. The nozzle shaft and the nozzle head define a portion of a fluid pathway extending from an inlet end of the housing body to a set of directional nozzles disposed at a discharge end of the nozzle head. The nozzle shaft and the nozzle head are configured to rotate together in response to a discharge of a liquid from the set of directional nozzles. The nozzle assembly also includes a friction brake assembly housed within the housing body. The friction brake assembly converts a centrifugal force generated by a rotation of the nozzle shaft and the nozzle head into an axial force that reduces a rate of rotation of the nozzle shaft and the nozzle head into a desired range.

A sprinkler module is cooperable with a sprinkler nozzle unit supporting a sprinkler nozzle to define a sprinkler configuration. The sprinkler module includes a cage attachable to the sprinkler nozzle unit and including a pair of struts, a cap connected to the cage via the pair of struts, and a deflector plate cooperable with the sprinkler nozzle and rotatably secured between the cap and the cage. The deflector plate includes a hub extending through the cap. A plate gear with gear teeth is secured to the hub and is rotatable with the deflector plate, and a cover assembly is connected to the cap. The cover assembly includes a brake gear coupled with a brake assembly, where the brake gear is disposed in a path of the gear teeth.
