In one aspect, a sprinkler is provided having a nozzle, a deflector that receives fluid flow from the nozzle, and a friction or viscous brake assembly that controls rotation of a deflector. The friction or viscous 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 includes a pop-up deflector plate that is engageable with a brake assembly in an extended position. A brake module is secured to a sprinkler body and includes a rotatable connector coupled with the brake assembly. The pop-up deflector plate is disposed adjacent the nozzle and engages the rotatable connector in the extended position.

A cone valve assembly including an upper valve member with a conical top portion and a stepped and spiraled top surface and a lower valve member including a central opening with a stepped and spiraled valve surface surrounding the central opening. The upper valve member is mounted in the lower valve member such that the lower valve member is rotatable and axially movable relative to the upper valve member. Rotation of the lower valve member allows for the adjustment of an arcuate slot opening that provides a conically shaped discharge stream of water from the cone valve nozzle assembly directly onto the rotating distributor to provide the desired arc of sprinkler coverage.

An irrigation nozzle with a rotating deflector is provided whose rotational speed may be controlled by a friction brake. The nozzle may also include an arc adjustment valve having two portions that helically engage each other to define an opening that may be adjusted at the top of the sprinkler to a desired arcuate length. The arcuate length may be adjusted by pressing down and rotating a deflector to directly actuate the valve. The nozzle may also include a radius reduction valve that may be adjusted by actuation of an outer wall of the nozzle. Rotation of the outer wall causes a flow control member to move axially to or away from an inlet.

A sprinkler includes a pop-up deflector plate that is engageable with a brake assembly in an extended position. A brake module is secured to a sprinkler body and includes a rotatable connector coupled with the brake assembly. The pop-up deflector plate is disposed adjacent the nozzle and engages the rotatable connector in the extended position.

A rotary nozzle sprinkler includes a base assembly with a bearing, a stem mounted rotatably in the bearing, and an elbow coupled at a proximal end to and rotatable with the stem and including an elbow bend. A nozzle is secured to a distal end of the elbow, and a diffuser assembly including a brake mechanism is cooperable with the elbow. By positioning the nozzle downstream of the elbow, the sprinkler can achieve a greater throw radius.

An irrigation nozzle with a rotating deflector is provided whose rotational speed may be controlled by a friction brake. The nozzle may also include an arc adjustment valve having two portions that helically engage each other to define an opening that may be adjusted at the top of the sprinkler to a desired arcuate length. The arcuate length may be adjusted by pressing down and rotating a deflector to directly actuate the valve. The nozzle may also include a radius reduction valve that may be adjusted by actuation of an outer wall of the nozzle. Rotation of the outer wall causes a flow control member to move axially to or away from an inlet.

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.

Provided is a rotary sprinkler that includes a housing, a rotatable irrigation head associated with a first magnet assembly, and a second magnet assembly associated with the housing and fitted with a rotary dampening mechanism. The first magnet assembly and the second magnet assembly are arranged with like poles facing each other so as to generate a repulsion force therebetween.

A system for painting a structure includes a motorized, wheeled vehicle that is movable along a surface and includes a frame and a lift structure coupled with the frame. The system also includes a support structure supported by the lift structure, and a table supported by the support structure. The table is translatable relative to the support structure. The system also includes a mount structure rotatably coupled with the table and a kit of parts that includes a spray head assembly configured for releasable attachment to the mount structure. The system further includes a paint reservoir and a pump, each being supported by one of the vehicle and the support structure.
