ABSTRACT:
A speed control device for a vehicle driven by an internal combustion engine comprises a longitudinally movable actuator member connected to the accelerator control linkage of the engine, a longitudinally movable abutment member, a device for optionally locking the abutment member against longitudinal movement, a spring and a flexible diaphragm connecting the actuator and abutment members, and means for applying manifold vacuum from the internal combustion engine to the diaphragm whereby to vary the relative positions of the actuator and abutment members. Preferably the device locking the abutment member is controlled by an acceleration responsive device so as to unlock the abutment whenever the vehicle is subjected to more than a predetermined degree of deceleration.
