Quick connect device and assembly for use with a toilet fill valve

Abstract

An assembly comprising a tubular inlet riser adapted to be mounted within a toilet tank where a main control valve assembly would be mounted on the upper end of the inlet riser, the tubular inlet riser having an inner riser bore so that fill water can pass through this bore when the tank empties in accordance with the main control valve assembly, the inlet riser having a bottom-most portion having an outer threaded portion and a bottom seat, the assembly further comprising a quick connect coupling.

1 . An assembly comprising
 a tubular inlet riser adapted to be mounted within a toilet tank where a main control valve assembly would be mounted on the upper end of the inlet riser, the tubular inlet riser comprising   an inner riser bore so that fill water can pass through this bore when the tank empties in accordance with the main control valve assembly,   the inlet riser having a bottom-most portion having an outer threaded portion and a bottom seat, the assembly further comprising   a half cartridge adapter structure hermetically bonded to the bottom seat of the inlet riser and extending upwardly into the bore of the tubular inlet riser, the adapter structure comprising   a cylindrical upper tube stop cavity,   a cylindrical medial O-ring cavity and   a cylindrical lower cartridge cavity.   
     
     
         2 . An assembly comprising a tubular inlet riser adapted to be mounted within a toilet tank where a main control valve assembly would be mounted on the upper end of the inlet riser, the tubular inlet riser having
 an inner riser bore so that fill water can pass through this bore when the tank empties in accordance with the main control valve assembly,   the inlet riser having a bottom-most portion having an outer threaded portion and a bottom seat, the assembly further comprising   a standard coupling nut, the coupling nut having a side wall and an end wall having a centrally-disposed circular aperture, inside of the side wall, the coupling nut has internal threads adapted to mesh with the threaded portion of the inlet riser, the inside of the coupling nut further comprising a flat inner surface of the end wall, and   a cone washer having a centrally-disposed circular aperture,   a ramped shoulder that extends downwardly from the aperture to a vertical outer sidewall, and a substantially flat bottom surface,   the assembly further comprises a substantially tubular male insert having an upper portion and a lower portion, the lower portion having an outer cylindrical surface, the insert having a substantially cylindrical inner bore, and disposed between the upper and lower portions of the male insert is a flat peripheral flange, the flange having a top surface and a bottom surface, the upper portion of the male insert being adapted to be placed within the aperture of the cone washer and the lower portion to extend through the end wall aperture of the coupling nut.
