ABSTRACT:
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 be closed or opened to a selected extent by the actuator.
