In an air filter system for an internal combustion engine having a fresh air line with an air inlet, a filter housing with an upper housing half and lower housing half, a filter element disposed in the filter housing, a clean air outlet opening with an adjoining clean air line opening into the intake system of the internal combustion engine, and means for damping intake noise, the means for damping the intake noise is a sheet configured and arranged adjacent, and clamped to, the upper housing half opposite the clean air outlet whereby the intake noise vibration energy is absorbed by frictional relative movement between the sheet and the upper housing half, the intake noise being damped by a change in impedance, in particular by a jump in impedance.

Air filter system

In a vibration dampening support arrangement for supporting a component on a support structure such that it is removable only in a predetermined direction of removal, a projection extends from the support structure at an angle .alpha. of 12.degree. to 60.degree. with respect to the direction of removal and an elastic element is disposed on the projection in form-locking engagement with the component in the predetermined direction of removal but is unreleasably held in any other direction.
