Patent ID: 8413440

Claim:
A method for regulating an outlet pressure in an outlet of a fresh-gas supply device, the method comprising the steps of: determining operating parameters of an operating state of an internal combustion engine arranged downstream of the outlet of the fresh-gas supply device; blocking a connection of the outlet to a charge-air inlet of the fresh-gas supply device by closing an adjusting device arranged in the connection of the outlet to the charge-air inlet if one or more determined operating parameters indicate an acceleration of the internal combustion engine is required; opening a connection of the outlet to a compressed-air inlet by fully opening at least two valves between the outlet and the compressed air inlet in a pressure build-up phase; regulating the outlet pressure after opening the connection of the outlet to the compressed-air inlet by comparing the outlet pressure with a nominal pressure during a pressure-regulating phase and by separately opening and closing the at least two valves or by adjusting at least one of the at least two valves between an open and closed position in response to the result of the comparison of the outlet pressure with the nominal pressure; and when the inlet pressure has reached a defined and parameterizable value, closing the connection of the outlet to the compressed-air inlet by closing the at least two valves and opening the connection of the outlet to the charge-air inlet by opening the adjusting device.
