Abstract

Abstract A flush activation system is provided for controlling the drainage of water from a toilet flush tank during a flush. The system comprises a valve assembly; a displaceable flush lever assembly coupled to the valve assembly; at least one auxiliary assembly coupled to the flush lever assembly; and, an actuation assembly coupled to the auxiliary assembly. The valve assembly includes a valve member displaceable for initiating and terminating the drainage of water from the flush tank. The flush lever assembly is adapted to actuate the displacement of the valve member. The auxiliary assembly includes an activating arm having at least one activating float component coupled at a terminal end thereof, and is pivotally displaceable between angularly offset active and inactive positions. The activating arm is biased in orientation at both its active and inactive positions in angularly disposed directions away from a vertical orientation. It operates in its active position to actuate at least a portion of the flush lever assembly to maintain the valve member in such position to permit the drainage of water at least until the water level within the flush tank drops beyond a predetermined activating water level.
