Abstract
A fill valve assembly for a water tank such as a toilet tank. The fill valve assembly includes a head portion containing a valve mounted on top of a vertical water outlet tube and a float which moves vertically along the outlet tube to control the opening and closing of the valve. The float is vertically adjustable without removal or disassembly of the valve assembly in order to adjust the tank water level to a preselected position. The float includes an inverted cup-shaped structure which moves vertically along the outlet tube in response to any change in the water level. The valve contains a flexible main valve disk held in a closed position against a valve seat by water pressure in a control chamber to prevent the flow of water into the tank, and is moved to an open position upon venting of the control chamber. A pilot valve controls the pressure in the control chamber and, therefore, the movement of the main valve disk. The pilot valve is controlled by a lever mechanically connected to the float so that when the float drops with the falling water level the pilot valve is opened, thereby venting the control chamber and allowing the main valve disk to flex upwardly off of the valve seat to allow water to enter the tank. When the float rises with the rising water level to an upper predetermined position, the pilot valve is closed by the lever and the main valve disk is returned to its closed position against the valve seat to block the flow of water into the tank.
