A control (2) processes a signal of outlet pressure and compares it with a stored reference pressure. A signal is sent to a pressure regulation-unit and compressed air applied if necessary. Independent claims are also included for the following: (a) an air brake for a vehicle, especially a railed vehicle or truck; (b) a vehicle as above;and (c) an operating process for the above.",
