Title:
COMPRESSOR
Document Type and Number:
Japanese Patent JP2005240696
Kind Code:
A
Abstract:
To provide a compressor suppressing the decrease of compression efficiency in an operating region.
The compressor comprises a moving blade group 5 arranged in a centrifugal compression flow path 3 formed inside a casing 1, a main flow path 2 formed inside the casing 1 as an upstream side of the moving blade group 5, and a detouring flow path 14 formed upstream of the moving blade group 5 in an outer region of the main flow path 2. A downstream side port 15 of the detouring flow path 14 is located upstream of the upstream side end of the moving blade group 5. Such a positional relationship can expand operating range by addition of flow to the end of the moving blade, and suppress the decrease of compression efficiency.
