An irrigation device includes a body defining a fluid passage; a slider movably coupled to the body, wherein the slider includes a body defining a plurality of apertures and a plurality of projections extending away from the body; a plurality of flexible jets coupled longitudinally to the body, wherein the plurality of flexible jets receive fluid from the fluid passage, and wherein each jet is received by an aperture in the plurality of apertures of the slider; and a toggle rotatably coupled to the body and to the slider, wherein the toggle is rotatably coupled to the body in substantial alignment with the plurality of jets, and wherein rotation of the toggle in a first direction moves the slider to cause at least one projection of the slider to engage with at least one jet to adjust a position of the at least one jet.

An adjustable rotary nozzle assembly in accordance with an embodiment of the present disclosure includes an upper valve element mounted in a drive element such that the upper valve element rotates with the drive element, wherein the drive element and upper valve element are mounted in a base and a lower valve element is mounted in a bottom of the base in a desired orientation relative to the base and the upper valve element such that the upper valve element and lower valve element cooperate to provide an adjustable arcuate slot opening though which water passes.

A spraying device, which includes a spraying mechanism and a rotating mechanism is disclosed. The rotating mechanism includes a rotating sidewall, which sidewall is provided with multiple sets of spraying holes arranged along the circumference of the rotating sidewall. Each set of spraying holes includes a plurality of spraying holes, and the spraying holes of at least two adjacent sets of spraying holes are arranged in a staggered arrangement. The spraying mechanism includes an infusion channel, the sidewall of which is provided with a spraying spout. The infusion channel extends along the inside of the rotating sidewall, the rotating sidewall being configured to rotate or swing with respect to the spraying spout of the infusion channel.

A water sprinkler includes a housing and an ejection head. An impeller is assembled in the housing, pushed by water, and connected to a cam. A water-hit target is pivoted with the housing via a compression spring, and an impacted portion of the water-hit target is extending outside of the housing. The water-hit target repeatedly impacts the housing because of the pivoting motion caused by the pushing of water flow and by the pulling of the compression spring, so that the housing is pivoted to change the ejection direction of the ejection head. A water baffling cover is pivoted with the housing. A abutted member is assembled on the water baffling cover and abutted against the cam. The cam can push the abutted member to drive the pivoting motion of the water baffling cover, so that the water baffling cover shields the ejection head by different extents.

A fluid discharging system having a pump and a discharging spray head having at least one nozzle through which fluid to be discharged exits is provided. The pump has a stator and a rotor which is attached in a chamber of the stator and can be rotated in relation to the stator about a rotational axis and axially along the axis. The axial displacement of the rotor in a first axial direction is configured such that it brings about pump filling operation. A fluid is drawn via an inlet into the stator chamber, and the axial displacement in an opposite second axial direction is configured such that it brings about discharging operation. The fluid in the chamber is expelled out of an outlet of the pump. The outlet of the pump is arranged in the rotor, and the discharging spray head is fluidically connected to the outlet of the pump.

A rotating distributor for use in a rotary type sprinkler is conically shaped and includes a plurality of water channels provided on a bottom surface thereof to guide water from a center axis of the distributor radially outward to an outer circumference of the distributor. The grooves are provided to collect and guide the water with a minimum of spray and turbulence and to impart rotation on the distributor. The depth of the grooves may be used to control flow and range as desired. An elevation control ring may be provided to vary the elevation angle of water leaving the grooves to control range. A kick angle control element may be provided to modify a kick angle at an outer circumferential end of selected grooves to provide speed control, if desired.

In a method of controlling a rotary sprinkler, a first angular position and a first watering distance are accessed from memory using a controller. A first electric motor is driven using the controller based on the first angular position. A head comprising at least one nozzle is rotated to the first angular position responsive to driving a first electric motor. A second electric motor is driven using the controller based on the first watering distance. A valve is positioned in a first valve position responsive to driving a second electric motor. Water is discharged through the valve and the at least one nozzle. The head is held at the first angular position for a first time period based on the first watering distance.

An impingement sprinkler includes a main frame and a tubular structure rotatably mounted onto a lower portion of the main frame. A sprinkling device is laterally mounted onto the main frame and an impinging device is pivotally mounted on the sprinkling device. The impinging device continually impinges the sprinkling device for intermittently rotating the main frame relative to the tubular structure when the sprinkling device continually sprinkles. A reversing device is mounted onto the sprinkling device for controlling the irrigating area of the impingement sprinkler. A trigger is connected to the reversing device and two limit rods horizontally pivotally mounted on the tubular structure, wherein a poke rod is pivotally connected to the trigger and absolutely limited between two limit rods so as to enable steering of the impingement sprinkler.

A bearing assembly suitable for a fluid delivery system such as a hydraulic water cannon, including for a first pipe that is moveable relative to a second pipe, the assembly comprising a main body adapted to be connected to an end of the first pipe, an annular centre swivel adapted to be connected to an end of the second pipe, the centre swivel including an annular, axially extending boss extending away from the main body, with the opposed radially extending face extending radially outwardly from said boss, and a bearing end cap adapted to engage around the second pipe and be fastened to the main body securing there between said centre swivel. The bearing assembly is adapted to operate at water pressures greater than 10 bar.
