Abstract: A wide-band damper is designed for charge air lines of an internal combustion engine with turbocharger. The wide-band damper has an inlet and an outlet. Proceeding from the inlet, at least three slot chambers are arranged axially in series. The slot chambers are dimensioned for different frequencies f1, f2 and f3. At least three gap chambers are provided, which are arranged axially in series and axially downstream of the at least three slot chambers. The gap chambers are dimensioned for different frequencies f6, f7 and f8. Each of the frequencies f1, f2 and f3 of the slot chambers is lower than each of the frequencies f6, f7 and f8 of the gap chambers.
Abstract: A disc damper for a charge air line of an internal combustion engine that has a turbocharger. The disc damper includes an inlet, an outlet, and at least one slit chamber disposed between the inlet and outlet. Starting from the inlet, at least two gap chambers are provided downstream of the slit chamber and disposed axially one after the other. At least one of the following features is fulfilled: a) the slit chamber has a radial inner dimension that changes in the circumferential direction and/or b) the slit chamber has axial inner dimensions that change in the circumferential direction, and/or at least one gap chamber comprises radial inner dimensions that change in the circumferential direction.
