Abstract
An exhaust pressure actuated valve assembly for placement inside a tubular exhaust conduit includes a valve plate rotatable between open and closed positions. An axle is adapted to pivotally couple the valve plate to the exhaust conduit about a longitudinal axis of the axle. The axle axis is adapted to extend in a direction substantially perpendicular to a direction of exhaust flow through the conduit. A cantilevered spring pad has a first portion coupled to the valve plate and a second portion spaced apart from the valve plate. The second portion is oriented to contact an inner surface of the conduit as the valve plate moves toward the closed position to dampen vibration.
