ABSTRACT:
A two level flush valve assembly for use in a water tank of a conventional toilet. An essentially cylindrical, hollow valve body has an upper flush opening, a lower flush opening, an overflow pipe and a discharge opening. The valve body is positioned in the interior of a toilet water tank with its lower end extending downward through an opening in the bottom of the tank. An extension arm is fastened to the free end of the lever arm which is operated by the flush handle of the toilet. A pulley is rotatably mounted on the free end of the extension arm and operatively engaged by a chain which interconnects a pair of valve elements pivotedly connected to the valve body for closing the upper flush opening and the lower flush opening. The valve element which closes the upper flush opening is pivoted open by the pulley and chain mechanism in response to movement of the flush handle, lever arm and extension arm for approximately one-half of their total distance of travel. Movement of the flush handle, lever arm and extension arm for their total distance of travel pivots both of the valve elements open.
