Abstract

The present invention relates to a compressor ( 1 ) of an exhaust-gas turbocharger having a compressor housing ( 2 ) which has a compressor outlet connecting pipe ( 3 ), and having a sound absorber ( 4 ), wherein the sound absorber ( 4 ) is formed as a separate component which can be connected to the outlet connecting pipe ( 3 ).

First claim

The invention claimed is:

1. A compressor ( 1 ) of an exhaust-gas turbocharger with a clip-on easily exchangeable sound absorber for sound related adjustment, comprising:
a compressor housing ( 2 ) which has a compressor outlet connecting pipe ( 3 ), and
a sound absorber ( 4 ) in the form of a shell having exterior walls ( 22 , 24 ) arranged around the outside of the compressor outlet connecting pipe, the sound absorber having in its interior two axially spaced chambers ( 14 , 15 ) which are separated from each other by at least one internal radial wall ( 23 ), wherein
the outlet connecting pipe ( 3 ) has two circumferentially elongate radial connecting ducts ( 12 , 13 ) in communication with the two chambers of the sound absorber,
the sound absorber ( 4 ) is formed as a separate component releasably connected to the outlet connecting pipe ( 3 ) and adapted to the sound-related requirements of the compressor ( 1 ), and
the sound absorber ( 4 ) is clipped onto the outlet connecting pipe ( 3 ) by means of:
(i) a separate holding element ( 10 ) after the sound absorber ( 4 ) is pushed on the outlet connecting pipe ( 3 ) or (ii)
(ii) a multiplicity of clips ( 8 , 9 ) provided on the end side ( 7 ) of the sound absorber ( 4 ) pointing away from the compressor housing ( 2 ) and which, in an assembled state, engage into a holding groove ( 6 ) of the outlet connecting pipe ( 3 ).

2. The compressor as claimed in claim 1 , wherein the sound absorber ( 4 ) is constructed from shell components ( 16 , 16 ′) adapted to be connected to one another.

3. The compressor as claimed in claim 2 , wherein the shell components ( 16 , 16 ′) are half shells.

4. The compressor as claimed in claim 3 , wherein the shell components ( 16 , 16 ′) are differently-shaped components.

5. The compressor as claimed in claim 1 , wherein the outlet connecting pipe ( 3 ) is further in communication with the first and second axially spaced chambers ( 14 , 15 ) via two additional circumferentially elongate radial connecting ducts ( 12 ′, 13 ′).
