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.

Variable restriction valve for vehicle exhaust system

An exhaust line element comprises a valve body, a shutter, a pivot link connecting the shutter to the valve body, an upstream tube, and a downstream tube. At least one first stopper is attached on an inner surface of the valve body. The shutter abuts against the first stopper in the closing off position. The first stopper defines a longitudinal position of at least one of the upstream tube and the downstream tube relative to the valve body.
