Abstract
A valve assembly for a vehicle exhaust system includes a rigid mount structure that is configured to be mounted within an exhaust component that defines an exhaust gas passage. The valve assembly further includes a plurality of flexible members that each extend from a first end to a second end. One of the first ends and second ends of the flexible members is fixed to the rigid mount structure and the other of the first ends and second ends is free to move such that the plurality of flexible members creates a variable restriction to flow through the exhaust component that varies in response to a pressure difference upstream and downstream of the plurality of flexible members.
