摘要

The compressor (1) has a rotatable shaft (4) stored in a bearing housing (6), where a compressor wheel (3) is fixed outside the bearing housing. A compressor housing (7) is surrounded by the compressor wheel that comprises an axial intake guide (8) on the bearing housing, where the bearing housing is arranged on an opposite side of the compressor wheel and a spiral housing (9). An axial spacer (18) is attached to the intake guide such that the spacer measures distance between the intake guide and the bearing housing. A rear wall (10) of the compressor housing comprises a recess. An independent claim is also included for a turbo supercharger comprising a turbine.
