  • Patent number: 10799891
    Abstract: A linear oscillating water jet is capable of spraying in a linear oscillating fashion without deviating from a consistent linear path such that a resulting linear spray does not extend beyond a targeted area. Through the use of an internal turbine, energy from an incoming pressurized liquid is used to create rotational motion, which is subsequently converted into an oscillatory, back and forth linear motion by way of a rocker assembly that connects a nozzle assembly to the internal turbine. The oscillatory, linear motion of the rocker assembly is translated into a linear, back and forth rocking motion for the nozzle assembly.

  • Patent number: 9844488
    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.

    Abstract: A rotating high pressure air and water nozzle is disclosed. The nozzle includes a head adapted to rotate, a housing adapted to secure the head therein, and a plurality of passageways disposed through the head. In addition, the nozzle includes a supply port disposed at a first end of each of the passageways, where each supply port has a funnel shape adapted to direct fluid into each passageway to reduce hydraulic losses, and a discharge port disposed at an opposing end of each of the passageways adapted to discharge a jet of fluid. Each discharge port is offset from the respective supply port to cause the head to rotate when fluid flows through the passageways.
