The quantity of water which is discharged from a flushing tank into a toilet bowl is regulated by accelerating or decelerating the descent of a float in a housing which is installed in the tank. The float carries an actuator which is provided with a valving element serving to seal an outlet of the tank when the float descends in the housing to a selected level as a result of flow of water from the housing into the tank through one or more openings in the housing. Each opening is controlled by a discrete valve which can he closed or opened to a selected extent by the actuator.

Why it's free to use
- Filed June 29, 1993. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended June 29, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 29, 2015.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
