Abstract
A linkage extends between an actuator and a valve in a turbocharger. The linkage comprises two spaced member bodies having central portions with opposing curved shapes that extend between ends translatable along and rotatable about spaced pivots. Translation of one member toward the other member compresses the central portions, increasing overall stiffness of the linkage, and translation of one member away from the other member creates a gap between the central portions, allowing independent translation of the ends along the spaced pivots to compensate for misalignment between the actuator and the valve caused by heat and vibration. Another linkage extending between an actuator and a valve in a turbocharger includes two planar spaced member bodies extending between ends translatable along and rotatable about spaced pivots. The two member bodies have different thicknesses.
