Abstract: An exhaust-gas flap device, including for the exhaust-gas flow of an internal combustion engine, has a flap pipe and a flap plate that is supported in the interior of the flap pipe on a pivot shaft. The pivot shaft is rotatable about a pivot axis (A). The pivot shaft has first and second axial end regions and is supported rotatably on the flap pipe by respective first and second bearing assemblies. The pivot shaft is configured, in the first axial end region, for coupling to a drive element of a pivot drive. The pivot shaft is, in at least one of the axial end regions, in contact with vibration-damping material that is supported relative to the flap pipe.

Abstract: A coupling arrangement is disclosed for the rotational coupling of a drive element of a pivoting drive of an exhaust-gas flap for the exhaust-gas flow of a combustion engine to a pivot shaft rotatable about a pivot axis. A first coupling element has a coupling region coupled to a pivot shaft for rotation about the pivot axis. A preload element generates a force acting on the first coupling element and the second coupling element in a peripheral direction with respect to one another and generates a force acting in an axial direction between the coupling elements. One of the coupling elements includes two radially outwardly extending rotational coupling projections and the other coupling element includes a rotational coupling cutout receiving the projection. The one coupling element is held axially on the other coupling element by the preload element to prevent the projections from moving out of the cutouts.

Abstract: A control flap assembly for a gas flow in a fuel cell system, in particular in a vehicle, includes a control flap housing providing a gas flow channel, and a control flap with a disk-like control flap body which can be adjusted in the control flap housing between a closed position preventing a gas flow through the gas flow channel and at least one open position opening up the gas flow channel for a throughflow. A control flap seat is provided on the control flap housing, and a sealing region bearing against the control flap seat in the closed position of the control flap is provided on the control flap. The sealing region includes resilient sealing material on an external peripheral region of the control flap body.

Abstract: A fuel-cell exhaust system for a fuel-cell arrangement, in particular in a vehicle, includes a fuel-cell exhaust line through which fuel-cell exhaust gas can flow and a condenser having a condenser body through which the fuel-cell exhaust gas can flow. With the condenser, liquid is condensed out of the fuel-cell exhaust gas. A liquid separator is arranged downstream of the condenser.
