Abstract: A heat recovery component for an exhaust gas system comprises: an inlet; an outlet; a first branch conduit comprising a first inlet, a first inlet axis, a first outlet, and a heat exchanger; a second branch conduit parallel to the first branch conduit, separate and thermally separated from the first branch conduit and comprising a second inlet, a second inlet axis, and a second outlet; and a valve arranged at the first inlet and the second inlet. The valve comprises separate first and second valve flaps fixedly arranged on a shaft and extending in a plane defined by the first and second inlet axes and perpendicular to the first and second inlet axes. The first valve flap is arranged at an axial location on the shaft corresponding to the location of the first inlet, and the second valve flap is arranged at an axial location corresponding to the second inlet. The valve flaps are arranged angularly rotated relative to one another about the shaft.

Abstract: A muffler shell (1) for use in an exhaust system of a vehicle comprises an inner metal sheet (13) and an outer metal sheet (10). The outer metal sheet (10) is arranged to enclose the inner metal sheet (13). The muffler shell further comprises a vibro-acoustical dampening material (14) sandwiched between the inner metal sheet (13) and the outer metal sheet (10). Both the inner metal sheet (13) and the outer metal sheet (10) are corrugated sheets made of stainless steel having a thickness in the range of 0.15 mm to 0.30 mm. The vibro-acoustical dampening material has a thickness (T) in the range of 4 mm to 8 mm and a density in the range of 130 kg/m3 to 160 kg/m3.
