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.
Claims5
A method for preventing binding of a multi-button selector assembly in a toilet flush valve, comprising the steps of:
- providing a shuttle with an opening;
- configuring the shuttle to be movable between a first position associated with a first flush volume and a second position associated with a second flush volume less than the first flush volume;
- configuring a first button in the selector assembly to move the shuttle to the first position;
- configuring a second button in the selector assembly to move the shuttle to the second position;
- inadvertently pressing the first button and the second button at the same time;
- and
- during the inadvertent step, enlarging the opening.
