  • Valve device for exhaust flow passage
    Patent number: 10571036
    Abstract: A link couples a support body and a valve body in a first arrangement where a first link-forming member is rotationally movably supported by the support body and in which a second link-forming member is rotationally movably supported by the valve body. The link includes: a link length that is a length of the first link-forming member, as measured between a rotation axis with respect to the support body and a rotation axis with respect to the second link-forming member; and a link length that is a length of the second link-forming member, as measured between a rotation axis with respect to the valve body and a rotation axis with respect to the first link-forming member. The link lengths differ from each other. The link is also configured to enable coupling between the support body and the valve body in a second arrangement inverted with respect to the first arrangement.
