摘要:
A shaft seal arrangement for turbochargers comprises a two piece wear washer for preventing passage of bearing lubricant into the turbocharger turbine housing. The two pieces of the wear washer seal respectively with the turbocharger shaft and with the turbocharger bearing housing. The two pieces of the wear washer further cooperate with each other to form a radially displaceable seal arrangement to accommodate radial excursions of the shaft without leakage of bearing lubricant.
