A bypass valve assembly for a turbocharger includes a bypass valve having a valve stem rotatable about a valve stem axis for opening and closing the valve. The end of a first crank of an articulated two-bar linkage is connected to the valve stem. The end of a second crank of the linkage is connected to a cam follower engaged with a guide cam. An actuator provides motive force to the cam follower to proceed along the guide cam, which is configured to advance the cam follower along a guide path that is non-linear and non-circular arc, causing the two-bar linkage to rotate the valve stem. Valve stem angular displacement versus actuator stroke can be altered by modification of the shape of the guide path.
