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.

In order to provide a trailer coupling device for motor vehicles, comprising a rear-side cross member which is mountable on a vehicle body, a supporting unit provided on the cross member which holds a ball neck receiving sleeve having a ball neck receptacle in which a ball neck incorporating a coupling ball is insertable and fixable therein, in which the ball neck receiving sleeve is minimally visible and disturbing when the ball neck is not inserted, it is proposed that the supporting unit comprises a pivot bearing unit by means of which the ball neck receiving sleeve is pivotable from a working position in which the ball neck is insertable therein in order to use a trailer, into a rest position in which an insertion opening of the ball neck receiving sleeve is arranged outside a visible region.
摘要:
A unit for recovering thermal energy from exhaust gas of an internal combustion engine including an inlet, an outlet, a heat exchanger arranged downstream of the inlet and upstream of the outlet, and a valve capable of being switched between a recovery position. The exhaust gas flows from the inlet through the heat exchanger to the outlet, and a bypass position, in which the exhaust gas flows from the inlet through a bypass to the outlet. The valve includes separate first and second valve bodies and associated separate first and second valve seats arranged upstream and downstream of the heat exchanger, respectively. The first and second valve bodies are adapted to be switched only simultaneously from the recovery position to the bypass position and vice versa.
