A float arm inter connection device for a cistern inlet valve

摘要

A method and apparatus are disclosed for actuating an inlet valve (12) of a cistern or flush tank. The cistern has a float arm (13) connected to a valve actuator (35) by a gear mechanism which preferably takes the form of a rack (27) and pinion (28). A substantial increase in effective gear/force ratio is achieved together with conversion of arcuate motion of the float arm (13) into linear motion of the actuator (35).
