Abstract
The invention relates to a safety device for an automotive pneumatic system, whereby a safety valve comprising a restoring element is provided. The invention also relates to a method which enables an automotive pneumatic system to operate in a safety mode. Components such as the pressure control valve, the regeneration valve and a circuit protection device can be actuated in a normal operational mode. One of said components fails to function in the safety mode. The inventive safety device is characterized in that the force of the restoring element can be adjusted. The inventive method is characterized in that the restoring element of the safety valve is discharged in the safety mode.
