Abstract
A variable turbine geometry assembly for controlling flow of exhaust gas to a turbine wheel of a turbocharger includes an adjustment ring extending about an axis and rotatable about the axis, at least one vane lever coupled to the adjustment ring, and at least one vane coupled to the at least one vane lever. The at least one vane is moveable with respect to the adjustment ring when the adjustment ring rotates about the axis. The variable turbine geometry assembly further includes a wave spring operably in contact with at least one of the at least one vane lever and the adjustment ring. The wave spring is configured to bias one of the at least one vane lever and the adjustment ring toward the other of the at least one vane lever and the adjustment ring.
