Fresh gas supply device for an internal combustion engine and method of operating same

A fresh gas supply device for an internal combustion engine having an exhaust gas turbocharger, the fresh gas supply device comprising:

• a charge air inlet for inlet of compressed charge air flow from the exhaust gas turbocharger;
• an outlet connected to the charge air inlet;
• a valve portion arranged between the charge air inlet and the outlet, the valve portion being closeable by at least one valve in a closing position that blocks the compressed charge air flow from the exhaust gas turbocharger to the outlet;
• an adjusting device coupled to the at least one valve for adjusting the at least one valve into the closing position;
• and
• a compressed air inlet for inlet of compressed air into the outlet, the compressed air inlet being operatively arranged to direct the compressed air from the compressed air inlet in a direction toward the at least one valve such that the compressed air from the compressed air inlet impinges against an outlet side of the at least one valve in a manner that assists movement of the at least one valve to the closing position.
