Abstract
A radial compressor, with a rotor-side impeller, a stator-side housing, an inflow passage via which medium to be compressed can be fed to the impeller in the axial direction, a diffuser via which compressed medium can be conducted in the radial direction away from the impeller in the direction of a spiral housing section of the housing The diffuser radially outside in a transition region to the spiral housing section has an enlarging flow cross section.
Claims10
A radial compressor of a turbocharger, comprising:
- a rotor-side impeller;
- a stator-side housing having a spiral housing section;
- an inflow passage, via which a medium to be compressed can be fed to the rotor-side impeller in an axial direction;
- and
- a diffuser, via which compressed medium can be conducted in a radial direction away from the rotor-side impeller and towards the spiral housing section of the stator-side housing,
- wherein the diffuser has an enlarging flow cross section radially outside in a transition region to the spiral housing section.

A turbocharger, comprising:
- a turbine for expanding a first medium;
- a radial compressor configured to compress a second medium utilising energy extracted during expansion of the first medium, comprising:
- a rotor-side impeller;
- a stator-side housing having a spiral housing section;
- an inflow passage, via which the second medium is fed to the rotor-side impeller in an axial direction;
- and
- a diffuser, via which compressed second medium can be conducted in a radial direction away from the rotor-side impeller and
- towards the spiral housing section of the stator-side housing, wherein the diffuser has an enlarging flow cross section radially outside in a transition region to the spiral housing section.
