An oscillating sprinkler that includes a frame with a first boom and a second boom engaged therewith. The booms are oriented generally parallel to each other and each of the first and second booms rotates about an axis that extends along the boom's length of the respective first or second boom. The first and second booms rotate in opposite directions to each other and are synchronized so that they rotate toward each other or away from each other in unison. First and second booms are operatively engaged with gears that are driven by a water-powered motor. One or more valves may be provided to shut off or reduce water flow from one or both of the booms. The watering pattern from the booms is such that water tends to be more evenly distributed over a ground surface upon which the sprinkler is placed.

Disclosed is a part circle mechanism assembly mounted on a sprinkler. The part circle mechanism assembly comprises a base with a symmetrical rotational structure. The symmetrical structure further comprises a plurality of contact faces. Further a lower trip is mounted on the base. The part circle mechanism assembly further comprises an upper trip mounted on the base. At least two sector rings are mounted on the sprinkler. At least one sector ring from the at least two sector rings is in contact with the lower trip. Further the part circle mechanism assembly comprises a trip spring mounted on both tripsupper and lower. The trip spring is configured to actuate the upper trip to reverse a motion of the sprinkler. Further a cover is configured to snap fit on the base.

A shower water rotating structure includes a main body having a water inlet and water outlet, and a rotating disk, pinion, water inclining support, impeller and rotors arranged top to bottom inside the main body; the water inclining support has inclined water inlet adapted to guide water flow to impact the impeller to rotate the impeller configured with a drive gear adapted to drive the pinion to rotate; the pinion is configured with a guide rod adapted to drive the rotating disk to rotate; the rotating disk is distributed radially with guide grooves for the staged matching with the guide rod; and a lower part of rotating disk is configured with a gear adapted to drive the rotors having an inclined water hole and capable of being rotated in the water outlet of the main body, thereby realize spray having a pulsating rotating water effect.

A distribution valve of an in-floor pool cleaning system is provided. The distribution valve includes a housing having an inlet port and a plurality of outlet ports. A turbine within the housing rotates about a shaft in response to fluid flowing through the inlet port. The turbine is releasably coupled to a gear mechanism, and the gear mechanism is releasably coupled to a distribution valve disk, the disk having an aperture therein. As the turbine rotates, the gear mechanism also rotates and drives the rotation of the disk around the shaft. The rotation of the disk sequentially places the aperture over one of the plurality of outlet ports, thus allowing fluid to flow out of the outlet port over which the aperture is positioned, but restricting fluid flow into any of the outlet ports that are covered by the disk.

A gyrating nozzle head spray gun includes grip including air inlet, valve seat, gas-delivery tube connected to valve seat and terminating in mating connection screw rod and trigger operable for letting external compressed air go into air inlet and gas-delivery tube, attachment tube connected to mating connection screw rod of the gas-delivery tube, gyrating nozzle head assembly including gas-supply tube connected to mating connection screw rod and suspended in attachment tube, bearing, cap, linking module and gyrating nozzle head mounted on one end of the gas-supply tube, and water-delivery tube having one end extended bottom of coupling hole of gas-delivery tube and connected to water tank for sucking in water and opposite end thereof inserted through gyrating nozzle head for ejecting fluid for creating mist of fine droplets upon ejection of compressed air through the gas-supply tube and oblique jet hole and central axle hole of the gyrating nozzle head.

An improved sprinkler structure provides a fastener of a positioning ring for elastically fastening a water guiding pipe. A fastening dot of the positioning ring can engage with a tooth of a water inlet connector effectively so that the water guiding pipe does not detach easily. Water outlet direction of a first water passage and a second water passage is tangent with an impeller; therefore, when water is let out, the water pressure will push the impeller evenly to make the sprinkler to rotate evenly and smoothly. A push rod of a water inlet switching device is pivotally connected with a connecting rod. When the connecting rod is pushed, because a clearance is present between the connecting rod and a connecting groove, the force received by the connecting rod is partially converted into momentum of displacement when the push rod wiggles.

The present invention is directed to a rotor or sprinkler that allows its watering arc to be rotated, increased, or decreased by user-rotation of the sprinkler's rotating nozzle base.

A cleaning head for an in-floor pool cleaning system is provided. The cleaning head includes a sleeve having a passage and an insert extending through the passage of the sleeve. The insert includes a flow path and an aperture, wherein the flow path is a curved, such as a question mark shape, and exits through the aperture. The insert is moveable between a first position with the aperture retained with in the sleeve and a second position with the aperture extending beyond the sleeve. The flow path may include an overturn at the aperture. The insert includes a nozzle, a nozzle housing, an upper guide, a lower guide and a weight with the flow path extending through each component. The nozzle includes an angled inlet opening that corresponds to an angled outlet opening of the nozzle housing that engage each other when the nozzle is coupled within the nozzle housing.
