locking links 106 108 are identical and pivotally connected together each link 106 108 has a lower protrusion 106 a 108 a and an upper shoulder 106 b 108 b respectively best seen in fig6 the links 106 108 are arranged so that in a locked position the lower protrusion 106 a engages the upper shoulder 108 b while the lower protrusion 108 a is urged upward by the valve reset lever 110 the valve reset lever 110 also is pivotally connected to a float linkage 112 preferably the links 106 108 the lever 110 and the linkage 112 are coupled by pins 114 the float linkage 112 is secured to a buoyant float 116 that can move up or down on an elongated body 118 of the fill valve assembly 100 the valve release lever 104 is elongated and includes an attachment end 120 and an opposite free end 122 the free end 122 of the lever 104 is roughly parallel the float linkage 112 in the full tank position the attachment end 120 has a pivot pin 124 that extends through the cap 126 of the fill valve assembly 100 and pivotally connects the lever 104 to the cap 126 the pivot pin 124 includes a cam 128 for unlocking the links 106 108 during flushing the pivot pin 124 may also serve as a banking surface for the links 106 108 when in the locked position the links 106 108 are coupled to a valve member 130 which.
