<p>A diverter valve for a fluid storage tank such as the storage tank of a water closet is disclosed. In one embodiment, the diverter valve has a housing with an inlet passage for receiving a supply of water and a pair of outlet passages. One of the outlet passages delivers pressurized water from the diverter valve to the storage tank, and the other outlet passage delivers the pressurized water to a diversion conduit connected to the toilet bowl rim. The diverter valve also includes a movable flap mounted within the diverter valve which moves to proportion the flow of water between the two outlet passages in response to changes in the water level of the tank. The flap is initially positioned to direct water to the tank when the tank water level is high. The flap is then moved by a water level sensor such as a float to direct water to the bowl rim when the water level in the storage tank has dropped below a pre-determined diversion level. Flow to the bowl rim continues even after the tank has emptied. A special bleed line in communication with the supply line is provided to allow a portion of the water supply to flow into the storage tank even when the water level is below the diversion level, so as to refill the tank.</p> |
