handle 38 pivoting the plunger 36 about pivot 130 such that the inner end of the plunger pivots resulting in a changed flush volume the embodiments illustrated in fig3 d f have a pivot point 130 proximate the valve body the positioning of the pivot point at the opposite end of the plunger 36 from the handle 38 results in an increased need for a plunger 36 handle 38 interface able to create a moment to pivot the plunger 36 motion of the handle 38 pivots the plunger 36 about the pivot 130 resulting in a changed flush volume the interface of the handle 38 and the plunger 36 maybe any of the various designs that achieve the movement of the plunger 36 about the pivot point 130 as dictated by statics as such the embodiments utilizing at the inner end i e proximate the valve body 11 rather than the handle 38 generally require a plunger head 83 and or a handle face plate 58 which has a particular shape designed to create a moment in one embodiment the plunger 36 of fig3 a and b include head 83 having a flattened conical shape best illustrated in fig6 a downward movement of the handle 38 pivots the plunger upward in this embodiment the plunger head 83 may comprise any shape to enable the creation of a moment to pivot the plunger about the axis for example an alternative embodiment utilizes an inverted flattened conical shape and imparts the opposite relationship between handle 38 movement and plunger.
