Abstract:
A dual flush assembly for a flapper valve having a valve rotatable about a pivot when actuated for opening the valve, the assembly comprising:a guide adapted to the valve and extending at least a partly between the valve and the pivot; a weight movable along the guide for varying a turning moment of the weight, guide and valve about the pivot; and a resettable latch adapted for connection to a tensile member for actuating the latch between two positions, a short flush position wherein when the valve is pivoted upwardly, the latch remains latched and the weight is maintained adjacent the valve for maximizing the turning moment for closing the valve, and a long flush position wherein when the valve is pivoted upwardly, the latch is released so the weight moves closer to the pivot, for minimizing the turning moment to close the valve, and once the valve closes, the weight moves adjacent the valve and the latch resets in the short flush position.
