A sprinkler nozzle is configured for a sprinkler positioned at a distal end of a center pivot irrigation system. The sprinkler nozzle includes a connection part securable to the sprinkler, and a nozzle opening downstream of the connection part. A nozzle opening downstream of the connection part is part-toroidal shaped and partially blocked or skewed to control water flow to portions of the deflector plate according to a desired wetted area. The part-toroidal shape spans an arc less than 360 degrees. The nozzle enables a custom designed water application to complement the other sprinklers that are on the pivot and can be shaped to also apply water a distance beyond the end of the pivot pipe to match the application rate of the sprinklers along the pivot pipe.

A sprinkler includes a body defining (a) a passage having an inlet configured to be fluidly coupled to a source of fire suppressant fluid, (b) an outlet fluidly coupled to the passage, and (c) a compression pin aperture extending from an outer surface of the body to the passage and configured to receive a compression pin, a button received within the passage, and a seal engaging the button and the body to fluidly seal the inlet from the outlet. The compression pin aperture is positioned such that the compression pin engages the button to force the button against the seal when the compression pin is inserted into the compression pin aperture.

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 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 diffuser assembly for diffusing a liquid in irrigation plants has a supply conduit includes a diffuser with a nozzle adapted to direct a jet of liquid along a longitudinal axis, at least one deflector facing the nozzle for radially spraying the jet outwards, and a connection device for ensuring fluid connection of the diffuser to the supply conduit of the plant. The diffuser is mounted onto the irrigation plant with the axis extending in a substantially vertical direction and with the nozzle facing up, and the deflector is configured to rotate about the longitudinal axis, thereby causing oscillations in the assembly. The connection device includes a tubular body with end joints that connect to the diffuse, and the supply conduit and the body is monolithic with the joints and is made of a thermoplastic elastomeric base material. Furthermore, the body has an outer surface with annular folds, which imparts elasticity and damp the oscillations induced by the deflector. A pivot or linear irrigation plant includes a plurality of those diffuser assemblies.

The present disclosure discloses an anti-splash water outflow device comprises a water outflow body and an internal assembly. The internal assembly comprises an inner body that is rotatable relative to the water outflow body upon being impacted by water. The inner body is disposed with at least two spiral blades, and two adjacent spiral blades of the at least two spiral blades define a spiral water passage. The water flows into the water outflow body from the water inlet to impact the inner body to drive the inner body to rotate relative to the water outflow body, and the water flows through the spiral water passage, flows out of the outlet of the spiral water passage, flows spirally downward along an inner wall surface of the water outflow body, and sprays out of the water outlet to obtain an annular water spray shaped as a lampshade.

A dishwasher assembly may include a dishwasher rack including at least one drinkware row configured to hold drinkware along a length of the rack, a sprayer configured to provide at least one stream of liquid into the drinkware, and a paddle wheel assembly arranged between the drinkware row and the sprayer and including at least one paddle configured to rotate responsive to force of the at least one stream of liquid against the at least one paddle, such that during rotation the at least one paddle is configured to variably deflect at least a portion of the stream onto a plurality of portions of an interior surface of the drinkware.

A spray head comprises a body, a rotatable member, and a first bearing. The rotatable member is rotatably coupled to the body and includes a plurality of vanes and a plurality of spray nozzles. The first bearing is coupled to the body and is configured to define a rotational axis of the rotatable member. The first bearing includes a longitudinal channel and a plurality of distribution channels extending radially outwardly from the longitudinal channel through the first bearing. The first bearing is configured to direct a flow of water through the longitudinal channel and the plurality of distribution channels toward the plurality of vanes to rotate the rotatable member about the first bearing, so as to direct the flow of water through the plurality of spray nozzles.

A sprinkler head for irrigation having a sprinkler body. The sprinkler body surrounds a fluid delivery tube. The sprinkler body includes an upper plate and a lower plate. A and exits out the fluid nozzle. A fluid distribution cage is positioned on the sprinkler body and around the fluid delivery tube. The fluid distribution cage has one or more arms connecting an upper plate and a lower plate. The lower plate is configured to direct fluid sprayed onto it from the fluid delivery tube. When fluid is sprayed on the lower plate the upper plate begins to nutate around the fluid delivery tube between the upper sprinkler body plate and lower sprinkler body plate. The upper and lower sprinkler body plates have races configured for receiving one or more resilient cushions positioned on the upper plate of the fluid distribution cage. The upper cage plate or the lower sprinkler body plate has one or more projections positioned such that the fluid distribution cage hangs at an angle to facilitate initiation of nutation of the fluid distribution cage.

A garden sprinkler has an input base, an output member rotatably installed at the top of the input base, and a rotating member capable of driving the output member. The output Both sides of the output member are respectively equipped with a first outlet and a second outlet. The first outlet is equipped with a first sprinkler, and the second outlet is equipped with a second sprinkler and an adjusting sleeve. The second sprinkler is a side outlet and is screwed with the adjusting sleeve. The second sprinkler can be adjusted by the adjusting sleeve, which improves the convenience of sprinkling operation without multiple sprinkler heads.
