Abstract

A fresh gas supply device is provided for an internal combustion engine having a turbocharger. The device includes a charge-air inlet for taking in charge-air from the exhaust gas turbocharger, a compressed air inlet for taking in compressed air, an outlet connectable to the charge-air inlet via a flap element and to the compressed air inlet via a flow regulating device, and a control unit for controlling the flap element and the flow regulating device. The flow regulating device has at least one valve for opening and closing the compressed air inlet and a proportional valve connected downstream in the direction of flow for setting a pressure in the outlet.
