Beschreibung
Zusammenfassung:	The invention relates to a fresh gas supply device (7) for an internal combustion engine (1) having a turbocharger (2), said device (7) comprising the following: a charge air inlet (6) for taking in charge air from the exhaust gas turbocharger (2); a compressed air inlet (8) for taking in compressed air; an outlet (9) which can be connected to the charge air inlet (6) via a flap element (16) and to the compressed air inlet (8) via an amount controlling device (20) having a closed position and positions open to any extent, wherein the amount controlling device (20) is closed when the flap element (16) is partially or fully open; and a control unit (15) for controlling the flap element (16) and the amount controlling device (20) according to operating states of the internal combustion engine (1), wherein the amount controlling device (20) comprises at least one valve (21, 21') for opening and closing the compressed air inlet (8) and a proportional valve (23) connected downstream in the direction of flow for setting a pressure in the outlet (9). The invention also relates to a method for controlling a pressure in an outlet (9) of such a fresh gas supply device (7).
