SPRING SYSTEM TO REDUCE TURBOCHARGER WASTEGATE RATTLE NOISE

摘要

A turbocharger for a motor vehicle. The turbocharger includes a compressor mechanically coupled to a turbine. The wastegate of the turbine includes a valve head matched to a valve seat. The valve head is retained at one end of an actuator arm. A resilient spacer is arranged between the valve head and the actuator arm. The resilient spacer is configured to forcibly separate the valve head from the actuator arm when the valve head is unseated.
