Abstract
A float valve assembly for a water closet that has perfect seating control. The float valve can only move in an up and down direction and cannot move sideways. The float valve assembly has a float member that forms a valve which cooperates with a valve seat for opening and closing the flushing opening of the outlet coupling of the water closet. A pair of laterally spaced wire arm members have their one end pivotally attached to the top of the float member and their other end are pivotally attached to a C-shaped clamp that snaps onto the overflow tube within the water closet. A string-like member has its one end attached to the top of the float member and its opposite end can be attached to the free end of the actuating arm within the water closet.
Claims8
In a water closet, the combination of:
- (A) a flush tank for the storage of water, said tank having one opening in the bottom thereof and an outlet coupling located in said opening, the top of said outlet coupling is open and forms a valve seat, a substantially vertically oriented overflow tube has its lower end connected to said outlet coupling at a height below the top edge of said valve seat, a flushing drain pipe is connected to the lower end of said outlet coupling, and an actuating arm whose one end is connected to the lever that is used to flush the water closet;
- (B) a float valve assembly comprising:
- (1) a float member forming a valve cooperating with said valve seat for opening and closing the flushing opening of said outlet coupling, the valve seat of said outlet coupling having a predetermined diameter and said float member having a diameter greater than that of said valve seat, the bottom portion of said float member that seats on said valve seat being formed of polyvinyl chloride foam material, the bottom surface of said float member being substantially flat,
- (2) adaptor means for detachably securing said float valve assembly to said overflow tube,
- (3) flexible means connecting the top of said float member to the free end of said actuating arm,
- (4) substantially rigid connecting members having one of their ends pivotally attached to said adaptor means and their opposite ends pivotally attached to the top of said float member at a location spaced inwardly a predetermined distance from the peripheral edge of said float member thereby preventing said connecting members from pivoting downwardly any farther than the top surface of said float member.
