A sprinkler includes a body defining (a) a passage having an inlet and extending along a longitudinal axis and (b) an outlet fluidly coupled to the passage. The sprinkler includes a seal engaging a button and the body to fluidly seal the inlet from the outlet. A link and lever assembly includes a first lever and a second lever engaging the button. The first lever and the second lever each include (a) a leg positioned near a base end of the lever and extending outward from the longitudinal axis, the leg defining an engagement surface, (b) a head positioned near a tip end of the lever, and (c) a main body extending from the leg to the head. A fusible link limits movement of the heads. The engagement surfaces each engage a surface of the body to limit movement of the button along the longitudinal axis.

A deflector plate includes a flat or convex deflector surface and a plurality of deflector grooves extending radially outward from the deflector surface. The deflector surface is configured to deflect water outward into the plurality of deflector grooves.

A spray diffuser for a pool cleaner is coupled to the end of the tail sweep hose which expels pressurized water out of the end of the hose. The diffuser includes a flow shaping nozzle configured to form a diverging pressurized water stream. The shaping nozzle can be attached directly to the end of the hose with a flow obstruction of the shaping nozzle immediately adjacent the flow discharge. A dissipating portion dissipates the pressurized water stream when the spray diffuser is positioned above the surface of the water to prevent water spraying out of the pool.

An improved sprinkler distributor dampener utilizes at least one magnet and an electrically conductive material arranged so as to create an eddie current. The sprinkler is configured with a nozzle that directs fluid at the distributor. The distributor is configured to spin or rotate from the force of the fluid spray and thus distribute fluid in a randomized pattern. The dampener controls the speed of rotation of the distributor, which is preferably a distribution disc.

Disclosed is sprinkler system. The system comprises a gate valve. Further, a sprinkler frame is mounted on the gate valve. The sprinkler frame further consists of wires for connection. The system further comprises a generator. The generator is mechanically coupled with a rotor and a generator base. Further the system comprises of an electronic component. The system is housed in a sprinkler housing.

A washing liquid distribution device may be provided that includes a holder and an impeller. The holder may hold the impeller within a washing chamber of a dishwasher. The impeller may include a disc-shaped body provided with a plurality of impeller blades extending from a surface of the disc-shaped body. The impeller blades may include driving blades being angled in a first direction to cause rotation of the impeller when washing liquid is directed onto the driving blades. The impeller blades may include at least one backflow blade being angled in a second direction, where the second direction is opposite to the first direction. The present disclosure may also relate to a dishwasher including a washing liquid distribution device.

A sprinkler including a fixed base defining a water inlet and a nozzle, a rotating assembly arranged for rotation relative to the fixed based about a rotation axis and including a water stream director, receiving a pressurized stream of water from the nozzle and directing it in a generally radially outward direction and a rotation speed governing assembly operatively associated with the rotating assembly and operative to intermittently reduce a speed of rotation of the rotating assembly, so as to thereby increase a radial range of the stream, the rotational speed governing assembly including a rotating enclosure rotating together with the rotating assembly and enclosing a viscous material, a static element and a moving element.

A sprinkler assembly with a nutating distribution plate can improve even distribution of water. The distribution plate can tilt and/or translate upon water impinging the distribution plate to disperse water in different directions. The sprinkler assembly can have a deflector assembly including the distribution plate, a stem supported by a bearing, and a contact portion upstream of the distribution plate to contact an outer race that limits a range of movement of the distribution plate. The sprinkler assembly can be disassembled and reassembled with minimal tools and effort for servicing.

A spray diffuser for a pool cleaner is coupled to the end of the tail sweep hose which expels pressurized water out of the end of the hose. The diffuser includes a flow shaping nozzle configured to form a diverging pressurized water stream. The shaping nozzle can be attached directly to the end of the hose with a flow obstruction of the shaping nozzle immediately adjacent the flow discharge. A dissipating portion dissipates the pressurized water stream when the spray diffuser is positioned above the surface of the water to prevent water spraying out of the pool.

A self-cleaning solar panel assembly including a solar panel assembly having a peripheral frame, at least one sprayer mount assembly removably attachable to the peripheral frame, each of the at least one sprayer mount including a first element and a second element, both separate from the peripheral frame, the first element and the second element being removably joined together for clamping onto the peripheral frame and at least one sprayer mountable onto the at least one sprayer mount assembly.
