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.

An exhaust pressure actuated valve assembly for placement inside a tubular exhaust conduit, the valve assembly comprising:
- a valve plate being rotatable between open and closed positions;
- an axle adapted to pivotally couple the valve plate to the exhaust conduit about a longitudinal axis of the axle, the axle axis adapted to extend in a direction substantially perpendicular to a direction of exhaust flow through the conduit;
- and
- a cantilevered spring pad having a first portion coupled to the valve plate and a second portion spaced apart from the valve plate, the second portion being oriented to contact an inner surface of the conduit as the valve plate moves toward the closed position to dampen vibration.
An exhaust pressure actuated valve assembly for placement inside a tubular exhaust conduit, the valve assembly comprising:
- an axle extending through the conduit;
- a valve plate fixed to the axle and positioned in the conduit, the valve plate being rotatable between open and closed positions;
- and
- a spring pad including a first portion fixed to the valve plate and a second portion spaced apart from the valve plate such that the second portion is shaped as a cantilevered beam having one end fixed to the first portion and an opposite free distal end spaced apart from the valve plate, wherein the spring pad is positioned to contact an inner surface of the conduit when the valve plate is in the closed position.
