Abstract
An intake tract is provided for combustion air of a vehicle. The intake tract includes, but is not limited to an intake opening and an intake channel. At the end of the intake channel a sound source is arranged, which is sound-dampened by a sound damping device in the intake channel. An air filter is arranged between part regions of the intake channel and downstream of the air filter an air mass sensor is provided in an intake channel section, wherein the intake channel section of the air mass sensor includes, but is not limited to the sound damping device.

An intake tract for combustion air of a vehicle, comprising:
- an intake opening;
- an intake channel;
- a sound source arranged at an end of the intake channel;
- a sound damping device in the intake channel that is configured to sound-dampen the sound source;
- an air filter arranged between part regions of the intake channel;
- and
- an air mass sensor downstream of the air filter and arranged in an intake channel section,
- wherein the intake channel section of the air mass sensor comprises the sound damping device,
- wherein the sound damping device comprises a sound damping resonator coaxially configured to the intake channel section,
- wherein a radial coupling slit of the sound damping resonator is a flow direction-dependent open flow valve,
- wherein the radial coupling slit is arranged between an inner radial lip and an inner radial bead and downstream of the inner radial lip, and
- wherein axial orientations and cross sections of the inner radial lip and the inner radial bead determine a coupling direction of the sound damping resonator.
