Abstract
In a motion transmitting mechanism for controlling a power output control member such as a butterfly valve of an internal combustion engine, wherein a control input member is operatively connected to an input lever which cooperates with an output lever by means of a projection received on a guide slot formed in the input lever, the guide slot has first and second slot sections arranged at an angle and adapted to operate the output lever and the power output control member at a relatively small motion transmission ratio with a relatively large incremental operating force increase in a lower partial load range when the projection is in the first slot section and at a relatively high motion transmitting ratio with relatively small incremental operating force increase in a higher partial load range.
