Abstract
A damper valve assembly for an exhaust system of a vehicle includes a valve housing and a valve flap. The valve housing is adapted to be attached to a pipe of the exhaust system and defines an opening. The valve flap is rotatable relative to the valve housing and about a pivot axis between a first position whereat fluid flow through the opening of the valve housing is restricted and a second position whereat fluid flow through the opening of the valve housing is allowed. The valve flap includes a body and a mass damper. The mass damper is integral with the body and includes a plurality of segments that are folded so that the plurality of segments are in a stacked arrangement.

A damper valve assembly for an exhaust system of a vehicle, the damper valve assembly comprising:
- a valve housing adapted to be attached to a pipe of the exhaust system and defining an opening;
- and
- a valve flap rotatably coupled to the valve housing about a pivot axis, the valve flap movable between a first position whereat fluid flow through the opening of the valve housing is restricted and a second position whereat fluid flow through the opening of the valve housing is allowed, the valve flap including a body and a mass damper,
- wherein the mass damper is integral with the body and includes a plurality of segments that are folded such that the plurality of segments are in a stacked arrangement.
A damper valve assembly for an exhaust system of a vehicle, the damper valve assembly comprising:
- a valve housing adapted to be attached to a pipe of the exhaust system and defining an opening;
- a shaft rotatably coupled to the valve housing;
- a valve flap rotatable about a pivot axis of the shaft between a first position whereat fluid flow through the opening of the valve housing is restricted and a second position whereat fluid flow through the opening of the valve housing is allowed, the valve flap including a body and a mass damper;
- and
- a spring engaging the valve flap to bias the valve flap toward the first position,
- wherein the mass damper is integral with the body at a periphery thereof and includes a plurality of segments that are folded such that the plurality of segments are in a stacked arrangement.
A damper valve assembly for an exhaust system of a vehicle, the damper valve assembly comprising:
- a valve housing adapted to be attached to an end of a pipe of the exhaust system, the valve housing including a valve seat and an opening;
- a shaft coupled to the valve housing;
- a valve flap rotatable between a first position whereat the valve flap engages the valve seat and fluid flow through the opening of the valve housing is restricted and a second position whereat the valve flap is spaced apart from the valve seat and fluid flow through the opening of the valve housing is allowed, the valve flap including a body and a mass damper;
- and
- a spring engaging the valve flap to bias the valve flap toward the first position,
- wherein the mass damper and the body are formed from a single sheet, the mass damper including a plurality of segments that are folded such that the plurality of segments overlap one another.
