Abstract:
In combination;a water storage tank having a bottom, a discharge port in said bottom, and a peripheral sidewall adapted to store water at least to an upper storage level and to enable discharge of water through the discharge port to a lower level; a tank valve mounted to said tank having an inlet port an outlet port, and valve workings between said inlet and outlet ports to pass water under pressure when the ballcock valve is open, and a float responsive to water level to control said valve workings; a flush valve in said discharge port adapted selectively to close said discharge port to store water, and to open to release it in a flush operation, and an actuator operable to open said tank valve; a diverter valve comprising a base with a through passage extending from an inlet port to an outlet port having an axis and a lumen; a guide cylinder extending from said base with a central axis normal to the axis of the through passage having a cylindrical wall that intersects and opens into said through passage at said lumen; a tubular diverter plunger axially slidable in said cylinder, said diverter plunger having a central passage extending from end to end; a deflector surface on the end of said diverter plunger closest to said through passage so proportioned that when the diverter plunger is in its lowermost position it substantially occludes the lumen and deflects water upwardly into the central passage, and when the diverter plunger is sufficiently raised, the deflector is removed from said lumen; a pair of tank discharge tubes, one on each side of said plunger, a bridge conduit structurally joining and fluidly interconnecting said plunger with said discharge tubes; a float adjustably attached along both of said discharge tubes, whereby said float, discharge tubes, plunger and bridge conduit move vertically in unison for selecting different water levels, said float thereby biasing the diverter plunger upwardly and opening the through passage to flow when the water level in said tank is sufficiently high, the reaction between the deflector surface and flow of water from the ballcock valve holds the diverter plunger down with the deflector surface in the lumen during the time while the float is at a lower level and the ballcock valve is open; and a conduit from the outlet port of the diverter valve for conveying water to the toilet rim.
