  • Water jet aerator with diverter valve
    Patent number: 4800046
    Abstract: A water jet aerator in combination with a diverter valve including an aerator housing, a valve body that is rotatably positioned within the aerator housing, and a swivel nozzle. The aerator housing includes a water inlet conduit, a water outlet conduit, and an air inlet conduit, while the valve body forms two chambers, a diverter chamber and an aeration chamber. As the valve body is rotated in one direction within the aerator housing, water flow from the water inlet conduit to the aeration chamber is diverted to the water outlet conduit, while the air inlet conduit is proportionally closed to the aeration chamber. As the valve body is rotated in the other direction, water flow from the water inlet conduit to the water outlet conduit is diverted to the aeration chamber, while the air inlet conduit is proportionally opened to the aeration chamber.
