ABSTRACT:
A position control device for use in association with a foot pedal member controlling the fuel flow to an engine of a vehicle. The device includes an elongated and hollow chamber means and an actuator piston slidably disposed in the chamber means and movable between first and second positions therein. The first position represents a position of maximum fuel supply to the engine. Structure separately supporting the foot pedal member is provided for movement between first and second positions but permitting an operative connection of the foot pedal member to the actuator piston for movement along a path. A control device is provided for controlling the position of the actuator piston between the first and second positions and in response to vehicle speed and includes a yieldable resistance device for causing the actuator piston to resist a change in the position of the foot pedal member if an effort is made to alter the position of the foot pedal member toward the first position to increase the fuel supply to the engine and beyond the position of the actuator piston determined by the control means while simultaneously permitting an overpowering of the yieldable resistance device to effect a yieldable movement of the foot pedal member and the actuator piston together along the path to vary the fuel supply to the engine.
