Zusammenfassung:A valve assembly for an exhaust system includes a conduit, a valve flap disposed within an exhaust passageway for controlling exhaust flow through the exhaust passageway, a shaft supporting the valve flap in the exhaust passageway for rotation about a pivot axis, and a mass damper disposed external to the conduit and coupled to the shaft. The mass damper includes a longitudinal segment coupled to the shaft. The mass damper also includes a first damping mass that is disposed proximal to a first end of the longitudinal segment and is linearly movable along a centerline axis to a first distance with respect to the pivot axis. The mass damper further includes a second damping mass that is disposed proximal to a second end of the longitudinal segment and is linearly movable along the centerline axis to a second distance with respect to the pivot axis.
