Stabilizer channel of a compressor

A compressor comprising a compressor wheel and a stabilizer channel, the stabilizer channel comprising an annular stabilizer chamber which surrounds a main flow channel in the intake region of the compressor wheel,

• wherein the annular stabilizer channel is delimited with respect to the main flow channel by an annular web, the annular web having a first surface that defines a portion of the annular stabilizer chamber,
• wherein the annular stabilizer chamber is free of vanes and connected via a downstream inlet channel and an upstream outlet opening,
• wherein a plurality of flow-guiding elements are arranged in the downstream inlet channel, and
• wherein the downstream inlet channel is arranged between an upstream part of the annular web and a downstream, part of the annular web,
• wherein at least one of the following applies:
• i) the upstream part of the annular web comprises a first projection and the downstream part of the annular web comprises a second projection, wherein the first projection and the second projection extend away from the first surface of the annular web in the radial direction and into the annular stabilizer chamber, or
• (ii) the downstream part of the annular web comprises a third projection which extends in the axial direction into the annular stabilizer chamber such that the third projection overlaps a portion of the upstream part of the annular web, thereby forming the downstream inlet channel having a curved transition region.

A turbocharger comprising:

• a compressor comprising a compressor wheel and a stabilizer channel, the stabilizer channel comprising an annular stabilizer chamber which surrounds a main flow channel in the intake region of the compressor wheel,
• wherein the annular stabilizer chamber is delimited with respect to the main flow channel by an annular web, the annular web having a first surface that defines a portion of the annular stabilizer chamber,
• wherein the annular stabilizer chamber is free of vanes and connected via a downstream inlet channel and an upstream outlet opening,
• wherein a plurality of flow-guiding elements are arranged in the downstream inlet channel, and
• wherein the downstream inlet channel is arranged between an upstream part of the annular web and a downstream part of the annular web,
• wherein at least one of the following applies:
• (i) the upstream part of the annular web comprises a first projection and the downstream part of the annular web comprises a second projection, wherein the first projection and the second projection extend away from the first surface of the annular web in the radial direction and into the annular stabilizer chamber, or
• (ii) the downstream part of the annular web comprises a third projection which extends in the axial direction into the annular stabilizer chamber such that the third projection overlaps a portion of the upstream part of the annular web, thereby forming the downstream inlet channel having a curved transition region.
