Abstract
An exhaust-gas conduction component that is effective as a vibration decoupling element and can be installed in an exhaust-gas system for conducting the exhaust gases of a motor vehicle internal combustion engine. The exhaust-gas conduction component () has an outer pipe () with a corrugated metal tube section () and an inner pipe () that is coaxial with the outer pipe () and separated from the latter by an annular gap. The outer pipe () also has a smooth central section (), first and second corrugated metal tube sections () and smooth first and second end sections (). The inner pipe () is permanently fixed to the outer pipe () by a continuous joint () extending around the central section () and the rectilinear exhaust-gas conduction component () is approximately axially symmetrical in relation to a central transverse axis (). The exhaust-gas conduction component is especially suitable in utility vehicles for linking an emission control unit to an internal combustion engine.
