An exhaust gas control valve for regulating a flow of exhaust gas includes a housing having an interior wall defining a housing interior, a yoke disposed in the housing interior and having a length and an axis extending along the length, with the yoke being moveable between a first and second yoke position. The exhaust gas control valve further includes a valve member including a valve shaft and a valve body. The valve member is moveable between a first valve position and a second valve position. The exhaust gas control valve also includes a retainer coupled to the yoke, and a biasing member disposed in the housing interior and coupled to the yoke and the retainer to bias the yoke and the retainer in opposite directions, with the biasing member being configured to prevent free play of the yoke and the valve member with respect to said housing.

Exhaust gas control valve and assembly including the same

A number of variations may include a product comprising: a linkage system comprising: a first and second lever; a first interconnecting component and second interconnecting component operably connected to the first and second levers; a link bar having a first end with a first opening for receiving the first or second interconnecting component, and providing a clearance between the first opening and the first or second interconnecting component and; a second end with a second opening for receiving the first or second interconnecting component and providing a clearance between the second opening and the first or second interconnecting component; and a biasing device having a first and second end for engagement with the first and second interconnecting components and at least one section to allow for increasing or decreasing its length.

Biasing device for linkage system and method of making and using the same

A valve assembly includes a valve housing defining a bore with a first axis extending along a length of the bore, and a valve shaft partially disposed within the bore along a second axis that is perpendicular to the first axis. The valve assembly additionally includes a valve plate coupled to the valve shaft and disposed within the bore, and a restricting device including a stop member and an engagement member. The stop member extends from the valve housing and presents a stop surface. The engagement member extends from the valve shaft and presents an engagement surface. At least one of the stop surface and the engagement surface is non-parallel with the second axis. The at least one non-parallel surface engages the other of the stop member and the engagement member and biases the valve shaft axially along the second axis.
