Abstract
An assembly can include a turbine assembly that includes a wastegate; an actuator assembly that responds to a control signal to transition the wastegate from a closed position to an open position; a linkage assembly that includes a control coupling, a wastegate coupling, and a spring guide, where the wastegate coupling is operatively coupled to the wastegate and the control coupling is operatively coupled to the actuator assembly; and a spring assembly that includes a spring that includes an extension, where the extension forcibly contacts the spring guide at a closed angle of contact for the closed position of the wastegate and at an open angle of contact for the open position of the wastegate, where the open angle of contact is less than the closed angle of contact.
