ABSTRACT:
An internal combustion engine throttle control includes an extensible linkage connecting the throttle pedal to the butterfly valve. A linkage contraction spring urges the butterfly valve open and a butterfly return spring 22 urges it closed. The linkage is such that when the drivers foot is lifted from the pedal, a pedal return spring acts to shorten the linkage to its minimum extension and rapidly close the butterfly valve. A part of the linkage is urged by the linkage contraction spring against a cam forming part of a limited authority closed loop servo-mechanism, acting to limit throttle opening in accordance with one or more engine or vehicle parameters.
