Beschreibung
Zusammenfassung:	A turbocharger (10) having a bearing housing (14) between a turbine housing and a compressor housing with a shaped core (16) forming an internal oil drain cavity (20) adjacent to a spacer (24) shaped to induce swirling for oil defoaming. A depression (18) in an internal core wall of the bearing housing (14) forms the oil drain cavity (20) with each end (22) of the depression (18) corresponding to a distal end (30) of the spacer (24). The spacer (24) is preferably substantially tubular with a row of oil-flow apertures (32) aligned on each outer span (34) of a recessed center portion (28) to induce swirling.
