Abstract:
A vehicle pneumatics overpressure regulating circuit (1) of a supply device of a pneumatic consumer (5) in a vehicle having an operating pressure, havinga compressed air source (3), wherein said compressed air source (3) furnishes compressed air for the consumer (5), a pressure switch (8), wherein said pressure switch (8) turns the compressed air source on and/or off to supply the consumer (5) with compressed air, and a supply line (4), wherein compressed air is selectively carried out from the compressed air source (3) to the consumer (5), characterized in that the pressure switch (8), via a pneumatic measurement line (7) separated from the supply line (4), is selectively subjected to a measured pressure, wherein said measured pressure characterizes a state of the operating pressure of the consumer (5), wherein the pressure switch (8) is set such that if a predeterminable pressure switch point is undershot, a switch contact is actuated, whereby said compressed air source (3) is turned on, wherein the compressed air source (3) and the pressure switch (8) are disposed in a common housing, while the consumer (5) is spaced apart from this housing.
