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.
Claims1
Apparatus for flushing a toilet bowl, comprising a tank having a liquid confining space and an outlet for admission of liquid into the bowl;
- a housing having a chamber and an opening connecting said chamber with said space;
- a float provided in said chamber and arranged to descend in response to flow of liquid from said chamber;
- an actuator arranged to descend with said float, said actuator including a valving element and being movable to and from an operative position in which said valving element seals said outlet to prevent the flow of liquid from said space into the bowl;
- and means for regulating the movements of said actuator, said regulating means comprising means for controlling the rate of flow of liquid from said chamber into said space via said opening, and said controlling means having a first position in which liquid flows through said opening at a first flow rate, while said float and actuator descend at a first sink rate, so that said valving element seals said outlet upon evacuation of a first quantity of liquid through said outlet, said controlling means further having a second position in which liquid flows through said opening at a lower second flow rate, while said float and actuator descend at a lower second sink rate, so that said valving element seals said outlet upon evacuation of a greater second quantity of liquid through said outlet.
