Abstract: A vehicle speed control device in a vehicle having a variable speed engine and drive train arrangement connecting the engine to a drive wheel therefore includes a foot pedal movable in first and second directions, a vehicle speed transducer arrangement for generating a signal in response to vehicle speeds in excess of a predetermined speed and a control arrangement for varying the value of the predetermined speed. A throttle arrangement is responsive to movement of the foot pedal in the first direction for increasing the vehicle speed and is responsive to movement of the foot pedal in the second direction for decreasing the vehicle speed. A coupling arrangement transfers movement of a movable actuator to the foot pedal, to move the foot pedal in the first and second directions. A regulating arrangement is responsive to the signal of the speed transducer arrangement for regulating the vehicle speed at or just below the predetermined speed.

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.

Abstract: Saving fuel in the operation of a motor vehicle by providing an increased resistance to depression of a gas pedal at increased velocities in a predetermined speed range from a lower velocity up to a predetermined upper velocity. A piston is urged against the pedal by a spring in a cylinder. Adjustments in vacuum in the cylinder are utilized to adjust the spring force constituting the resistance to pedal depression of the piston.
