Patent ID: 8117687

Claim:
A diverter valve comprising: an inlet port coupled to a refill tube for receiving refill water; a first outlet port having an entrance and an exit; a bowl refill tube having a first end coupled to the exit of the first outlet port and a second end adjacent to a toilet tank overflow tube, the bowl refill tube providing a path of fluid communication between the first outlet port and the toilet tank overflow tube; a second outlet port having an entrance and an exit; a central flow passageway providing a path of fluid communication between the inlet port and the first and second outlet ports, the entrance of the first outlet port and the entrance of the second outlet port being directly opposite one another in the central flow passageway; a poppet slidably mounted in the central flow passageway, the poppet having a first raised position obstructing the entrance of the first outlet port and a second lowered position obstructing the entrance of the second outlet port; an actuating arm coupled to the poppet; a float member coupled to a rod and movable between a raised position and a lowered position; and a pivoting linkage having a first end coupled to the rod and a second end coupled to the actuating arm, the pivoting linkage translating downward motion of the rod into upward motion of the actuating arm and translating upward motion of the rod into downward motion of the actuating arm; wherein when water level in a toilet tank in which the diverter valve is mounted falls below a first predetermined level, the float member is in the lowered position and the poppet is in the first raised position obstructing the entrance of the first outlet port and preventing flow of refill water through the first outlet port into the bowl refill tube; and wherein when water level in the toilet tank rises above the first predetermined level, the float member is in the raised position and the poppet is in the second lowered position obstructing the entrance of the second outlet port and permitting flow of refill water through the first outlet port into the bowl refill tube.
