The peripheral plate portion has an opening for discharging the oil in the oil reservoir. The deflector further includes a tongue which extends from the plane of the recessed plate portion through the opening of the peripheral plate portion.

Oil sealing deflector

A lubricating oil sealing apparatus for use of a turbocharger having a compressor wheel for supplying a supercharged air through an intake passage, a turbine wheel driven by a force of an exhaust gas, and a driving shaft connecting the compressor wheel with the turbine wheel. The apparatus is located between the compressor wheel and turbine wheel, and has a labyrinth structure therein in order to prevent the lubricating oil from being suctioned into the intake passage.
