A sound damper for an exhaust gas system of an internal combustion engine includes a sound damper housing, at least one intermediate wall which is arranged in a housing interior and at least one sound damper connection pipe. The sound damper connection pipe is supported in a first pipe end region on the sound damper housing and is arranged in a second pipe end region on a support element which is arranged in the housing interior. The support element forms an integral component of an intermediate wall. The sound damper connection pipe introduces exhaust gas into the housing interior or directs exhaust gas out of the housing interior.

Sound damper

A decoupling element for an exhaust system () of a combustion engine, with an elastic exhaust gas-conducting body (), with at least one support ring () connected to the body () in a fixed manner, which encloses an axial end portion () of the body () on the outside in the circumferential direction (), and with at least one flange (), which is fastened to the support ring () by means of a weld seam (), wherein the flange () comprises a connecting piece (), which is inserted in the end portion () of the body () enclosed by the support ring (), and wherein the weld seam () is configured circumferential on the outside and connects an axial face end () of the support ring () facing away from the body () to the outer circumference () of the connecting piece () of the flange ().

Decoupling element for an exhaust system

A flange component part () for a component of an exhaust gas system for an internal combustion engine, in particular of a vehicle, has a flange (), which extends in a flange plane () and has a pipe section (), which projects away from the flange () at a longitudinal center axis (), which is perpendicular to the flange plane (). A cost-efficient producibility results when the flange component () is a sheet metal mold, which is produced from a single metal sheet () by means of metal forming.

Flange component part and production method

A muffler unit (), especially for a motor vehicle, has a two-part housing () with first and second housing parts () each of a shell-like design. An outlet opening and an inlet opening () are provided in the housing (). An outlet bottom () and an inlet bottom () are inserted into outlet opening () and into the inlet opening (), respectively. The outlet bottom () and inlet bottom () are designed each as a cover that can be inserted into outlet opening () and inlet opening ().
