ABSTRACT:
A fill valve for controlling liquid level in a toilet tank or other tank includes a housing with an inlet, an outlet, a valve, and a level sensing mechanism for opening the valve to permit flow when the liquid level is below a predetermined value. A flow impedance path including a compact array of many baffles defining multiple consecutive right angle turns dissipates fluid pressure without substantial velocity increases and consequent cavitation and noise. Stable valve closure when the predetermined level is reached is effected by the mounting and configuration of a valve control lever. The fill valve may be disassembled for service without removal from the tank. A coupling and mounting nut assembly facilitates mounting without tools in a variety of tanks. A backflow preventer including few simple parts may be incorporated to provide redundant cross-connection protection.
