ABSTRACT:
A vacuum and atmospheric air pressure actuated valve assembly which prevents re-energization of the servomotor of a vacuum actuated vehicle road speed control system after the brakes have been applied and the road speed control system de-energized. The device requires manual opening movement of the throttle valve by movement of the accelerator pedal, or stopping of the engine, to decrease the amount of vacuum sufficiently to let the device re-set to a condition which will permit the road speed control system to be re-energized.
