Method of assembling a lubricating oil sealing apparatus in a turbocharger.

摘要

A lubricating oil sealing apparatus for use of a turbocharger(1) having a compressor wheel (4) for supplying a supercharged air through an intake passage (9), a turbine wheel (2) driven by a force of an exhaust gas, and a driving shaft (3) connecting the compressor wheel (4) with the turbine wheel (2). The apparatus is located between the compressor wheel (4) and the turbine wheel (2), and has a labyrinth structure therein in order to prevent the lubricating oil from being suctioned into the intake passage (9). In order to facilitate assembly of the labyrinth seal, the central hub thereof, the encircling retainer (15) and the annular deflector member (16) are formed as a unit to reduce assembly time.
