Patent ID: 7891028

Claim:
A water-saving toilet flapper valve comprising of: a) a rounded flat section that is centrally positioned over a valve seat of a toilet tank and is radially extended beyond the diameter of said valve seat, b) an outer shell forming a flange body that is downwardly extended from said rounded flat section, said flange body of said water-saving toilet flapper valve is reinforced using radially extending reinforcing fins attached to a raised top portion and said rounded flat section of said toilet flapper valve, said flange body defines a hollow inner space, c) a solid inner core retained securely within said hollow inner space of said flange body whereby said solid inner core gives added weight to said toilet flapper valve and the interfacing of said rounded flat section and said flange body with said valve seat produces a positive seal, said solid inner core further comprises a protrusion formed in the inner wall of said recess, d) means for attaching said toilet flapper valve to an existing toilet flushing system including attaching said toilet flapper valve to a toilet flush handle and an overflow tube, whereby depressing said toilet flush handle causes said toilet flapper valve to raise and begin a flushing cycle, and d) a weighted mass retained securely within and by said solid inner core, said weighted mass gives additional weight to said toilet flapper valve, said weight mass comprises a cylindrical brass piece with a groove formed therein, wherein in the assembled configuration, said groove engaged said protrusion of said solid inner cord thereby allowing said weighted mass to be securely retained within and by said solid inner core, and said weighted mass has a free end extends outside of said hollow inner space of the flange body, wherein said solid inner core and said weighted mass entirely occupy said hollow inner space of said flange body, wherein said solid inner core comprises a dense airproof and waterproof hydraulic cement, wherein said solid inner core in conjunction with said weighted mass prevent any air pockets from forming inside said outer shell of said flange body and give the toilet flapper valve non-buoyancy and a combined weight, wherein said combined weight allows said toilet flapper valve to be manually operated with said toilet flush handle and allows said toilet flapper valve to quickly sink and come to rest on said valve seat when said toilet flush handle is released.
