Abstract

Abstract This application covers a water control valve for the water tank of a toilet bowl. The housing encloses a vertically movable plunger and an open-ended chamber into which water is admitted for filling the tank, together with mechanism for controlling the vertical or axial movement of the plunger. The housing includes two unitary molded sections - a body section and a cap section which can be joined together in assembling the valve structure, or they may be separated from each other. The body section has a plurality of peripherally arranged inverted L-shaped sections which are equally spaced from each other, while the cap section embodies a corresponding plurality of bayonet members. When the body and cap sections are to be interconnected to form the composite housing, the bayonet members are positioned between the corresponding L-shaped members and one of the sections is physically given a rotary twist or shift to complete the interconnection.
