  • Patent number: 7229031
    Abstract: A showerhead with an internal valve to control the flow of fluid between a full flow and reduced flow condition so as to save energy and thereby conserve the supply of water. The showerhead includes an internal valve that operates easily between an off position and an on position to permit a controlled flow of water from an approximate flow of two and one half gallons per minute to a reduced flow of about one half gallon per minute. The internal valve is formed in a spherical configuration and swivels or rotates between a reduced flow position and a full flow on position; it has formed therein a relatively small by-pass aperture that serves to selectively maintain a predetermined, constant temperature flow of water for a person taking a shower.

  • Patent number: 3935598
    Abstract: A toilet tank flapper valve providing user selection of either a full or partial dispensing of the liquid contents of the tank. A novel ball-check valve particularly located in the flapper valve either obstructs water from entering or permits it to enter the buoyancy chamber of the flapper valve. When water is permitted to enter, a partial dispensing action results.
