Device for sealing a bearing box of a turbocharger

摘要

The device has a seal (6) arranged between a rotor (2) and an intermediate wall (4). A drain-off device (8) conducts lubricant oil collected in an oil trap channel (42) into an oil drain (13) using gravitational force. The drain-off device is molded in a lower sector of a front surface of a wall attachment (40). The lower sector lies below a rotational axis (A) of the rotor. The drain-off device includes a drain surface aligned perpendicular to the axis. The drain surface is axially offset to a wheel pressure space (12) of a compressor housing relative to a remaining part of the front surface.
