Abstract
A flush valve is adapted to be mounted in the tank of a toilet and includes a selector assembly and a flush valve. The selector assembly is accessible from outside the toilet and provides for initiation of the flushing operation and an alternative choice between a larger flush water volume and a smaller flush water volume. A support structure provides for both axial and radial movement of the selector assembly relative to the flush valve in order to facilitate mounting and aligning of the flush valve assembly. A slide mechanism provides for variation of at least the smaller flush water volume.
