Title: TURBOCHARGER HAVING THRUST BEARING OIL RETAINER
Abstract:
A turbocharger (100) includes a turbine wheel (110), a compressor wheel (140), and a shaft (160) coupled to the turbine wheel (110) and the compressor wheel (140). The turbocharger (100) additionally includes a bearing housing (170) containing a thrust bearing (190) through which the shaft (160) extends. The bearing housing (170) receives oil and drains the oil therefrom. The bearing housing (170) includes a reservoir (184) that maintains a retained portion of the oil received in the bearing housing (170) after the oil is drained from the bearing housing (170). The retained portion of the oil lubricates the thrust bearing (190).
