| description | A snap-action valve assembly for an exhaust system is provided that includes a first conduit and a second conduit that are joined to together to define an exhaust passageway. A valve flap is disposed within the exhaust passageway for controlling exhaust flow. A shaft supports the valve flap in the exhaust passageway for rotation between open and closed positions. First and second bushings support the shaft. A pad made of wire mesh is attached to the valve flap. The pad includes an end portion that contacts the first or second conduit in the closed position and side wings that contact the first or second conduit in the open position. A resilient tongue may support the pad on an angle relative to the valve flap and a mass damper may be attached to one end of the shaft. These features dampen vibration and reduce valve flap flutter. |
