Mounting adapter and assembly for rendering fill valves for tank-type instantly dismountable

A combination of a diaphragm fill valve and a mounting assembly which renders the fill valve instantly mountable and dismountable from within the tank of a conventional tank-type toilet and the like having a hole in the bottom of the tank thereof for connecting the fill valve to a mounting assembly and adapted to be coupled for connecting the fill valve to a mounting assembly and adapted to be coupled to a water line delivering water to the tank, wherein:

• a. the mounting assembly comprises a mounting adapter which has a circular upper end adapted to be mounted onto the inner surface of the bottom of the tank and friction sealed thereto and a lower end adapted to be fitted through the hole in the bottom of the tank and connected to the water line;
• first sealing means for providing a water tight connection between the top of the mounting adapter and the fill valve;
• and second sealing means for providing water tight connection between the mounting adapter and the tank;
• and the mounting adapter comprises:
• (i) an outwardly projecting circular mounting platform on the upper end thereof having a lower surface with a hole in the center thereof;
• a circumferential circular vertical wall with a p 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;
• (ii) a unitary axially positioned hollow shank portion in water tight communication with and projecting downwardly from the lower surface of the mounting platform and adapted to be inserted from the interior of the tank through the bottom thereof and having a threaded exterior adapted to seal in cooperation with the second sealing means the mounting adapter to the tank;
• and
• b. the diaphragm fill valve is in a single motion digitally instantly rotably mountable and dismountable without the use of tools without dismounting the mounting assembly and 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.
