ABSTRACT:
A valve assembly for the control of discharge through the flush-water outlet of a tank for toilets or of other liquid storage tanks. It includes a flexible ball and float combination pivotably supported on the overflow tube in the tank for vertical swinging movement and so as to occupy a minimum amount of the limited space in the tank. In addition, it includes counterweight means in the form of a pair of water containers mounted on opposite sides of the pivoted support which fill with water from the tube so that when the valve support is swung into upper opening position, they will hold the support in that position with the valve unseated, to permit discharge of substantially all the water from the tank, but are provided with small metering discharge openings which gradually drain the containers until the weight of the valve and associated parts will cause it to drop into closed sealing position relative to the outlet.
