Abstract
An exhaust gas recirculation (EGR) valve assembly includes a valve housing with a wall defining a flow passage. The valve housing defines a bore communicating with the flow passage. A shaft is supported in the bore and extends into the flow passage. A flap is supported on the shaft in the flow passage. The flap is movable relative to the flow passage between a closed position and an open position. A sealing member projects from the wall into the flow path. The sealing member has a sealing surface that interacts with the flap in the closed position to inhibit gas flow through the flow passage, an opposite surface tapering toward the wall, and a circumferential end surface proximate and tapered away from the bore. The flap is coined against the sealing surface. A spider assembly is positioned between the shaft and a drive shaft of an actuator assembly.
