  • Patent number: 4868933
    Abstract: A flush control device for controlling the flush operation of a flush toilet having a cistern, a feed water control mechanism fluidly coupled to a water supply pipe and a flush water control mechanism fluidly coupled to one end of a flush pipe, the opposing end of which is connected to a toilet bowl. The flush control device includes a float coupled to the feed water control mechanism for operating the mechanism to stop water supply as the float reaches a predetermined water level. At the end of the flush operation, the descent of the float will operate the flush control mechanism to end the flow of water from the cistern to the flush pipe and operate the feed water control mechanism to supply water into the cistern again.
