Abstract
The invention creates a vehicle pneumatics overpressure regulating circuit of a supply device of a pneumatic consumer in a vehicle with an operating pressure. The overpressure circuit has a compressed air source , which furnishes compressed air for the consumer ; a pressure switch , by means of which the compressed air source is turned on and/or off to supply the consumer with compressed air; and a supply line , by way of which compressed air can be carried from the compressed air source to the consumer . The pressure switch can be subjected to a measured pressure via a pneumatic measurement line , which is separate from the supply line, and this measured pressure characterizes a state of the operating pressure of the consumer. As a result, extremely precise regulation of the requisite operating pressure is successfully achieved.
