A compressor oil seal comprising a thrust bearing (59) adapted for insertion into a turbocharger housing cavity (33), concentric with the turbocharger's compressor wheel shaft (11). An insert (360) is adapted for insertion into the cavity (33) adjacent the thrust bearing (59), wherein the thrust bearing (59) and insert (360) are configured to provide an oil drain cavity (35) therebetween. The oil seal also includes an oil flinger (340) that includes a flinger flange (382) and a sleeve portion (383) extending therefrom. The flinger flange (382) extends between the thrust bearing (59) and the insert (360). A plurality of spiral vane segments (74) are circumferentially spaced about the flinger flange (382). Each spiral vane segment (74) extends arcuately from a first end (372) to a second end (373). The spiral vane segments (74) are disposed between the flinger flange (382) and the insert (360). The spiral vane segments (74) may extend into a recess (363) formed into the insert (360), and the recess (363) may include at least one discharge port (370). |
