Centrifugal compressor and turbocharger
A centrifugal compressor includes: a housing including an intake flow path; a compressor impeller arranged in the intake flow path; an accommodation chamber formed upstream of the compressor impeller in a flow of intake air in the housing; a movable member arranged in the accommodation chamber; and an annular path formed in the housing, the annular path being connected to an outside of the housing, a heating medium supplied from the outside of the housing flowing through the annular path, at least a part of the annular path being located between the accommodation chamber and a leading edge of the compressor impeller.
1. A centrifugal compressor comprising:
a housing including an intake flow path;
a compressor impeller arranged in the intake flow path;
an accommodation chamber formed upstream of the compressor impeller in a flow of intake air in the housing;
a movable member arranged in the accommodation chamber; and
an annular path formed in the housing, the annular path being connected to an outside of the housing, a heating medium supplied from the outside of the housing flowing through the annular path, at least a part of the annular path being located between the accommodation chamber and a leading edge of the compressor impeller.
2. The centrifugal compressor according to claim 1 , wherein an intake port of the annular path is positioned vertically below a discharge port of the annular path.
3. The centrifugal compressor according to claim 1 , wherein a radially outer end of the annular path is located radially outside a radially outer end of the accommodation chamber.
4. The centrifugal compressor according to claim 2 , wherein a radially outer end of the annular path is located radially outside a radially outer end of the accommodation chamber.
5. The centrifugal compressor according to claim 1 , wherein a width of the radially outer end of the annular path is narrower than a width of a radially inner end.
6. The centrifugal compressor according to claim 2 , wherein a width of the radially outer end of the annular path is narrower than a width of a radially inner end.
7. The centrifugal compressor according to claim 3 , wherein a width of the radially outer end of the annular path is narrower than a width of a radially inner end.
8. The centrifugal compressor according to claim 4 , wherein a width of the radially outer end of the annular path is narrower than a width of a radially inner end.
9. A turbocharger comprising a centrifugal compressor according to claim 1 .
