A valve assembly includes a valve housing defining a flow passage configured to receive exhaust gas from an internal combustion engine, and defining a bore extending along a bore axis and fluidly coupled to said flow passage. The valve assembly also includes a valve body for controlling the flow of exhaust gas through the bore, and a shaft coupled to the valve body. The valve body is moveable between a closed position and an open position when the shaft rotates about the axis. The vale assembly additionally includes a first biasing member coupled to the shaft and configured to bias the shaft along the shaft axis in a first direction, and a second biasing member coupled to the shaft and configured to bias the valve body in the first direction along the shaft axis.

Valve assembly and exhaust gas recirculation system including 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.
