ABSTRACT:
Disclosed is a fill valve and mounting adapter assembly combination for tank-type toilets and the like which renders the fill valve internally and instantly mountable and dismountable without the necessity of separating the mounting adapter assembly from the tank and the water delivery line. The mounting adapter is T-shaped, hollow and provides water communication, when the adapter is mounted on the tank, through the interior of the adapter, between the water line and the interior of the tank and comprises an outwardly projecting circular platform on the upper end thereof having a lower surface with a hole in the center thereof and a circumferential circular vertical wall with a pair of inwardly projecting and opposing retention tabs at its upper end which tabs and the bottom wall and side wall of the platform form a recessed trough therein adapted to receive and seat a fill valve in the platform, which valve seats on a pair of o-ring seals providing a water tight seal between the fill valve and the mounting platform. A unitary axially positioned hollow shank portion in water tight communication with and projecting downwardly from the lower surface of the mounting platform has a threaded exterior adapted to seal in cooperation with mounting and connecting nuts the mounting assembly to the tank and to the water line. The fill valve is rendered instantly and digitally rotably mountable and dismountable from the tank of a tank-type toilet without disassembly of the mounting or connecting assemblies, which fill valve comprises a circular base having two opposing compression cams adapted to seat and seal the fill valve in the trough of the platform of the mounting adapter.
