Beschreibung
Zusammenfassung:	A snap-action valve assembly for an exhaust system and a method for manufacturing the same is provided. The valve assembly includes a first conduit and a second conduit that is partially received in the first conduit. A valve flap is disposed within the first conduit for controlling exhaust flow. A shaft supports the valve flap in the first conduit for rotation between open and closed positions. The first conduit has first and second slots, each extending from an open slot end to a closed slot end. First and second bushings supporting the shaft are disposed within the slots between the second conduit and the closed slot ends. A pad made of wire mesh is attached to the valve flap. The pad includes an end portion that contacts the first conduit in the closed position to dampen vibration and reduce valve flap flutter.
