发明名称 Wide-band damper for charge air lines of an internal combustion engine with turbocharger
摘要 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.

主权项 1. A wide-band damper for charge air lines of an internal combustion engine having a turbocharger, the wide-band damper, comprising: an inlet; an outlet; at least three slit chambers disposed axially one behind the other between the inlet and the outlet, the slit chambers each being dimensioned to dampen or insulate different frequencies f1, f2 and f3; and at least three gap chambers disposed axially one behind the other and axially between the slit chambers and the outlet, the gap chambers each being dimensioned to dampen or insulate different frequencies f6, f7 and f8, wherein each of the frequencies f1, f2 and f3 of the slit chambers is lower than each of the frequencies f6, f7 and f8 of the gap chambers.
