Body noise sink device for tube of exhaust gas arrangement, has cross section with impedance spring in axial direction, where impedance spring is provided in form of radial extension of cross section

摘要

The device has a cross section with an impedance spring in an axial direction, where the impedance spring is provided in the form of a radial extension (3) of the cross section. The radial extension is made of solid material, and is applied by welding, adhering or by shrinking on the cross section. The radial extension has a material thickness, which corresponds to a double wall thickness up to a double diameter of a tube (1).
