A rotary sprinkler riser extension kit is disclosed for use with a rotary sprinkler. The kit includes an external riser extension having an upper end and lower end, and defining a channel extending through the upper end and lower end. The channel is configured to accommodate the stem of the rotary sprinkler, the upper end is configured to attach to the cap of the rotary sprinkler, and the lower end is configured to attach to the enclosure of the rotary sprinkler. The kit also includes an internal riser extension having a height substantially equal to total length of the external riser extension, a width less than inner width of the enclosure of the rotary sprinkler, means for attaching to the geared lower end of the stem, a lower gear configured to rotate the rotary sprinkler, and means to raise the stem and channel water thereto in response to water pressure at an inlet to the enclosure.

A telescopic vehicle surface cleaning device comprising a washing unit, the washing unit comprising a nozzle carrier housing, a nozzle carrier and at least one fluid nozzle with at least one nozzle aperture, the nozzle carrier being movable relative to the nozzle carrier housing between first and second positions, the first position being a rest position and the second position being an extended position, the device further comprising a heating unit, the heating unit being configured as a heating sub assembly of the device and the heating unit comprising a heating element carrier with an electrically resistive heating element, the heating element carrier being fixed relative to the nozzle carrier housing and being configured such that the heating element is arranged in front of and adjacent to the nozzle aperture in the rest position of the nozzle carrier such that an air gap remains between a heating surface of the heating element and the nozzle aperture.

A rotating sprinkler includes a housing and a movable core. The core can assume retracted and extended states relative to the housing and incudes a cover, an impact member and a stream deflector. In the extended state, both the cover and the impact member can pivot between pivoted and non-pivoted states about a hinge defining an axis H generally orthogonal to axis X and the stream deflector is fixed against rotation about the hinge.

A nozzle is provided having a low precipitation rate and uniform fluid distribution to a desired arcuate span of coverage. The nozzle has an inflow port having a shape corresponding to the desired arc of coverage and a size for effecting a low precipitation rate. The nozzle also has a deflector surface with a water distribution profile including ribs for subdividing the fluid into multiple sets of fluid streams. There are at least two fluid streams for distant and close-in irrigation to provide relatively uniform distribution and coverage. The nozzle may be a unitary, one-piece, molded nozzle body including a mounting portion, an inflow port, and a deflector portion.

An improved underground sprinkler system having pop-up sprinklers installed within specifically arranged underground trenches. The kit comprises a flow control member that attaches to the water faucet can be manually or automatically switched between water zones where the underground sprinkler are placed.

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 system for lawns and landscaping is custom-fitted to each particular lot or area to be irrigated. Each in-ground, pop-up, rotating sprinkler head has a pattern defining plate fitted therein having a central opening made therein, as by laser cutting, solid particle deposition, or the like, the opening being congruent with the area to be watered, as adjusted for any sloped portions of the area. A pattern sampling aperture aligned with spray nozzles of the sprinkler rotates about the opening in the defining plate, feeding an amount of water to each radial line of the area about the sprinkler sufficient to reach from the sprinkler position out to the periphery. A speed control comprising a spring-biased cam and an opposing turbine wheel in the water flow slows spray head rotation at arc portions of longer water throw and speeds rotation where the throw is shorter, thus to obtain substantially uniform water coverage over all parts of the area served by each sprinkler head.
