Abstract
A valve device includes: a valve housing having a valve passage connected with an air flow passage; a valve disk rotatably disposed inside the valve housing through a valve driver and changing air flow cross-section of the valve passage; and a porous member installed at the valve disk and positioned in an open section between the valve disk and the valve passage.
Claims13
A valve device, comprising:
- a valve housing having a valve passage connected with an air flow passage of an exhaust system;
- a valve disk rotatably disposed to be spaced apart from the valve passage inside the valve housing through a valve driver and adjusting an air flow cross-section of the valve passage;
- and
- a porous member attached to the valve disk and disposed in an open section between the valve disk and the valve passage,
- wherein the porous member includes a mesh foam having a predetermined porosity.
