Abstract
A toilet flush system designed for manual control of the amount of water used for a toilet flush cycle uses a tank ball, flapper valve, or other type valves to control the closing of a reservoir outlet at selected times prior to or upon completion of the normal flush cycle. The tank ball or flapper valve is modified to overcome its buoyancy such that it rapidly closes the tank reservoir to thereby terminate the flush cycle when the handle of the toilet is released. By maintaining the handle in the operated position, the individual flush cycle can be controlled dependent on the waste to be disposed of, thus permitting a significant saving in fresh water. The buoyancy of the valve is overcome by utilizing a water absorbing material such as sponge material within the valve which, when primed, increases the weight of the valve.
Claims5
A toilet tank flushing assembly operable to discharge a controlled volume of water from a flush tank into a toilet bowl in accordance with the quantity and nature of the waste material to be flushed from the bowl comprising, in combination,
- a flush tank,
- a handle mounted on said flush tank,
- a valve seat disposed in the exit port of said tank,
- a flush valve adapted to engage said valve seat and thereby close said tank exit port,
- said flush valve having a substantially hollow interior portion with an opening in the bottom thereof,
- said interior portion of said flush valve including a water absorbing material adapted to modify the weight of said valve by controlling the amount of water admitted through said bottom portion of said flush valve, and
- a manually operated lever assembly connecting said handle to said flush valve,
- said modified flush valve being adapted to control the buoyancy of said float valve when said float valve is lifted from said valve seat and thereby control the reseating of said flush valve when said handle is released.
