Abstract: An exhaust muffler for an exhaust system of an internal combustion engine includes a muffler housing (12) with an outer shell (14) enclosing a muffler interior (22), through which exhaust gas can flow. An inner shell (54) is arranged in the muffler interior (22) and covers the outer shell (14) in at least some areas on an inner side (52) facing the muffler interior (22).

Abstract: A muffler for an exhaust gas system of an internal combustion engine. The muffler has a muffler housing having at least two interconnected housing shells delimiting a muffler interior. Each housing shell has a connecting edge extending away from the muffler interior. The housing shells are mutually connected by material bonding in the region of their mutually adjacent housing shell connecting edges. An insulating arrangement covers at least regions of the inner side of one of the housing shells. The insulating arrangement has an insulating shell with an insulating shell connecting edge extending away from the muffler interior and the insulating shell is arranged with the insulating shell connecting edge between the mutually adjacent connecting edges of the housing shells and is connected by material bonding to the connecting edges of the housing shells in the region of the insulating shell connecting edge.

Abstract: A three-way flap valve (4) includes an inlet (1), a first outlet (2), a second outlet (3), and a valve flap (5). The valve flap (5) can be moved between at least a first position and a second position. In the first position of the valve flap (5), fluid flowing in through the inlet (1) is directed to the first outlet (2). In the second position of the valve flap (5), fluid flowing in through the inlet (1) is directed to the second outlet (3). A surface (51) of the valve flap (5) circumscribed by an outer edge (53) includes at least a first surface section (A1), where the surface of the valve flap (5) has a curvature.
