A sprinkler device for delivering an irrigation liquid for gravity-based pivot or linear irrigation systems includes a support structure having a first portion with a nozzle defining a longitudinal axis for generating a jet of liquid, and a second portion with a baffle plate pivoted thereto and facing the nozzle. The second portion includes a drive system, which has a first magnet moving with a reciprocating oscillatory motion due to a negative pressure generated by the liquid that flows through the nozzle, and is configured to move the baffle plate along, and force it to pivot with a reciprocating oscillatory motion about the longitudinal axis through a predetermined angle, to thereby deliver the liquid over a sector area of the soil. A method of delivering an irrigation liquid for gravity-based pivot or linear irrigation systems that uses such a sprinkler device.

A jet former, including an impeller wheel rotatably mounted about an axis of rotation, having a blade arrangement, a control device, and at least one movably mounted nozzle. The control device is arranged and constructed to convert a rotation of the axis of rotation into a movement of the at least one nozzle. At least one blade of the blade arrangement is arranged and formed to divide the water flow directed towards the at least one blade in a direction of flow into at least a first partial flow and a further partial flow, to deviate the first partial flow in a first partial flow direction, and to deviate the other partial flow in a further partial flow direction. The direction of flow, the first partial flow direction and the further partial flow direction in each case differ from each other.

The invention discloses a water outlet device, which includes a shell part, a movable plate and a driving mechanism. The shell part is provided with a water outlet part. The driving mechanism connects the movable plate to drive the movable plate to slide relative to the water outlet part between the first position and the second position; the water outlet part has a water outlet, and the water outlet has a first inner side wall and a second inner side wall; the movable plate is provided with an insertion part, which has a first outer side wall and a second outer side wall side wall, and the insertion part is inserted into the water outlet; wherein: the movable plate is located in the first position: the water outlet forms a first water outlet channel sandwiched between the first outer side wall and the first inner side wall; the movable plate is located in the second position: the water outlet forms a second water outlet channel sandwiched between the second outer side wall and the second inner side wall, that is to say, the movable plate circulation makes the outlet water from the first water outlet channel to the second water outlet channel circulate to produce mixed water spray.

Nozzle assemblies adapted to produce an oscillatory spray pattern. A rotor member having at least one lobe engaged with one or more cavities of a stator surface for defining an oscillatory movement of the rotor member in response to a motive fluid along the rotor member and stator surface. The nozzle assembly directing the motive fluid along one or more tapered surfaces, such as complementary tapered surfaces of the rotor and stator surface. The rotor member is operatively coupled with the spray member for oscillatory movement therewith. The spray member adapted to receive the motive fluid and emit the fluid as a spray from the nozzle assembly. The spray having an oscillatory pattern that matches the oscillatory movement of the rotor.

A rinse device includes a housing part and a rinse head. The housing part has a first end configured to be attached to a supply of pressurised fluid and a second end to which the rinse head is attached, an axis X defined along the housing part from the first end to the second end. The housing part defining a cavity through which the pressurised fluid flows, in use, from the first end to the rinse head. The rinse head is provided with a plurality of openings through which the pressurised fluid is ejected. T housing part comprises an outer housing tube and an inner piston movable axially relative to the outer housing tube, and a spring attached at a first end to the outer housing tube and at a second end to the piston.

The present disclosure discloses a swing structure and a corresponding water outlet device. A water passing chamber in a body of the swing structure is equipped with a swing member, and an upper end of the swing member is provided with a recess facing a water inlet hole of the water passing chamber. The water flow impacts the recess to drive the swing member to swing to one side randomly. After a lower end of the swing member is out of range of a water outlet hole of the water passing chamber, the upper and lower ends of the swing member are adjacent to or abut against a wall of the water passing chamber, so that the swing member can swing back and forth.
