A filter unit () for the filtration of gaseous fluids has a filter web (), which is wound in a spiral about a support core (), and which is provided with parallel flow channels () for the fluid. Flow channels () which are directly adjacent to the support core, are covered by a cover element (), which is connected to a component of the filter unit ().

In various aspects of the invention a flow vortex suppression apparatus for use in an air intake duct having a mass air flow sensor is disclosed. The flow vortex suppression apparatus includes an air flow permeable fibrous vortex dispersive media installed into the air duct in a position upstream of the mass flow sensor and configured to occlude the air duct such that air flow in the duct is constrained to pass through the vortex dispersive media. The vortex dispersive media is configured and adapted to diffuse vortices and reduce air turbulence of an air stream entering the mass flow sensor, thereby reducing variations and noise in a flow measurement signal from the mass air flow sensor.

A device for noise transmission of an intake system of an internal combustion engine to the interior of a motor vehicle has a transmission line having an inlet at a first end and an exit provided with a mouth at a second end. A diaphragm is arranged at the second end to close off the mouth and to enable noise transmission. The inlet of the transmission line communicates with the intake system of the internal combustion engine. A protective device is arranged at the second end to protect the diaphragm.
