  • Patent number: 5206960
    Abstract: A dual flush toilet control mechanism includes an operating handle and attached actuating cam, a control arm and a control float arm. When the handle is turned in a first direction, the actuating cam moves the control arm to open fully a conventional toilet tank main valve to its buoyant position. When turned the handle is turned in a second direction, the actuating cam moves the control arm to open partially the main valve to a position wherein it is subject to the suction developed by the water exiting the toilet tank. A control cam on the control float arm maintains the control arm in position to maintain the main valve open against the suction until the water level in the tank drops below a predetermined level. When the float on the control float arm reaches the predetermined water level, the attached control cam allows the control arm to drop and the main valve to close.
