摘要： 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.

摘要： Covers a water control valve for the water tank of a toilet bowl in which the valve structure is constructed for better and more positive anti-siphonic action. The valve structure includes a plunger which is coupled by a lever arm to a float so that the plunger may move vertically within a chamber having a tapered wall in response to changes in the level of water in the tank. The chamber has an opening at the bottom for a valve seat which may be sealed by an elastomer affixed to the base of the plunger when the plunger reaches its lowermost position to close the valve. Near its upper end, the plunger has a collar for loosely supporting two elastomer disks of considerable elasticity to seal the upper end of the chamber for the anti-siphonic action. An additional flexible elastomer element is positioned on another collar of the plunger and is spaced from the tapered wall of the chamber throughout the stroke of the plunger in either direction. The anti-siphonic disks are located within a housing having a cap with a plurality of holes therein through which air may be admitted, and the cap is also provided with an overhanging canopy which blocks the admission of foreign matter to the chamber while permitting air to enter the chamber. The cap is joined to a body member to complete the housing, the body member providing the chamber in which the plunger is freely movable.
