Abstract: The invention relates to an exhaust gas treatment device for an exhaust system of a combustion engine, more preferably of a road vehicle, with a housing enveloping at least one interior space, and with at least one through-pipe penetrating the interior space without interruption and which at two fastening points distant from each other is connected to the housing in a fixed manner. For compensating thermally related expansion effects the through-pipe between the fastening points can comprise at least one expansion compensation section, in which a wall of the through-pipe comprises slits penetrating the wall alternating in circumferential direction and strips protruding relative to adjacent wall sections of the through-pipe.

Abstract: A holding device, for the holding of a component part of an exhaust system on a peripheral structure, more preferably of a vehicle equipped with the exhaust system, has a first connecting point for fastening the holding device to the component part of the exhaust system and a second connecting point for fastening the holding device to the structure. A coupling device is arranged between the connecting points which makes possible reversible relative movements between the connecting points. For improved holding function, the coupling device is configured such that in at least in one active direction the coupling device has a speed-dependent or frequency-dependent stiffness. The coupling device has a lower stiffness with slower or low-frequency relative movements than with faster or high-frequency relative movements.

Abstract: The present invention relates to a sheet metal component (1), in particular of an exhaust system, having a body (2) comprising at least two shells (3, 4), having at least one pipe (5), wherein at least two shells (3, 4) are joined together along butt edges (8, 9) that are in contact, wherein at least two shells (3, 4) form a tubular connecting area (10) in contact with the pipe (5) on the outside, into which the butt edges (8, 9) of the shells (3, 4) that have been joined together extend, wherein the pipe (5) is joined to these shells (3, 4) by a welded seam (11) which extends along an edge (12) of the shells (3, 4) in the connecting area (10), running around the pipe (5) on the end with regard to the longitudinal direction (13) of the pipe.

Abstract: The present invention relates to a muffler for an exhaust system of an internal combustion engine having an exhaust gas-carrying first pipe which is connectable to a first exhaust line of the exhaust system or forms an integral component of the first exhaust line, and an exhaust gas-carrying second pipe which is connectable to a second exhaust line of the exhaust system or forms an integral component of the second exhaust line. To design the muffler to be as compact as possible, a housing of the muffler includes a damper space situated between the pipes and has two longitudinal side walls each formed by a wall section of one of the pipes that is permeable for airborne sound.
