    Abstract: The high flow water return filling of the present invention is designed to connect directly to the end of a water return pipe in a swimming pool, spa, or the like. Water return fittings have been available for many years and have the primary purpose of returning filtered water back into a swimming pool, spa, or the like. However, the water return fitting of the present invention does not only return water into the swimming pool, it also substantially increases the water outflow so that a greater area of water in the pool can be circulated or agitated. In addition, the present invention has a uniquely curved nozzle that does not extend past the face plate, thus, the nozzle does not extend more than one inch from the swimming pool wall. The outflow from the nozzle creates a low pressure condition within the face plate.

The stem is tubular in shape and formed with a series of triangular openings through the wall thereof. Alternating triangular openings are oriented with their apexes facing downstream of the fluid with interspersed openings oriented with their apexes facing upstream. The triangular openings are isosceles in configuration. The stem may be formed integral with an inlet cap of the cleaning apparatus or as a separate component.

  • Publication number: 20140224278
    Abstract: Spray nozzle systems and methods of use are described herein. The spray nozzle system may include a stationary tube, a rigid rotor, and a sub-medium supply source. The stationary tube may be in fluid communication with a pressurized air source. The substantially rigid rotor is in fluid communication with the pressurized air source. The substantially rigid rotor includes a substantially rigid conduit that is in fluid communication with the passages of the stationary tube and the rotor. A portion of the conduit is substantially arched such that an outlet of the conduit is offset a radial distance in a radial direction from the rotor axis. Pressurized air ejected from the outlet produces directional components of the pressurized air in the direction of rotation about the rotor axis; and during use, the pressurized air rotates the rotor and sucks sub-medium from the sub-medium supply source into the stationary tube passage.

  • Patent number: 8777124
    Abstract: A sprinkler includes a turbine, a nozzle, a gear train reduction and a reversing mechanism that rotatably couples the gear train reduction and the nozzle. The gear train reduction includes an input stage and a planetary gear drive output stage that includes a first portion of the reversing mechanism. A second portion of the reversing mechanism is located outside of the gear train reduction. The second portion of the reversing mechanism includes a pair of arc tabs. At least one of the arc tabs is adjustable to establish an arc of coverage of the sprinkler when the water flowing past the turbine causes the gear train reduction and the reversing mechanism to oscillate the nozzle back and forth between a pair of arc stops. The arc stops are defined by the locations of the arc tabs. The input stage of the gear train reduction includes a mechanism that allows manual rotation of the nozzle between the arc stops without having to back drive the gears in the input stage.

  • Patent number: 8746592
    Abstract: An improved sprinkler has a flow altering device to change water direction and control the direction of a blade wheel. A gear set causes a sprinkler head's repetitive rotation. The sprinkler head includes a set of corresponding upper plate and lower plate to divide an interior chamber of the sprinkler head to two chambers: a control chamber and a gear chamber. A water inlet pipe connects only with the control chamber to provide water to enter the control chamber. The upper plate and the lower plate form a filtering channel interconnecting between the control chamber and the gear chamber. The water from the control chamber can flow into the gear chamber through the filtering channel. The filtering channel filters the large/coarser particle debris in the water and the water flowing into the gear chamber can lubricate and cool the gear set in the gear chamber.

  • Patent number: 8733674
    Abstract: A compact body spray nozzle is disclosed that includes a spray face that can be tilted to suit the requirements of the bather. The spray face is coupled to a spray body housing that is tiltable about the exterior surface of an internal stem driver ball. The stem driver ball is also coupled to a ceramic disk valve, and flow to the spray face through the ceramic disk valve is controlled by rotating the stem driver ball. An internal key index can be used to select a range of flow from the ceramic disk valve.
