Abstract
A compressor casing defines an air inlet port, an air intake passage with an impeller accommodated therein, a diffuser and a scroll all communicated with each other in the order named. An annually extending chamber is formed between the passage and the scroll and has an opening opened sideways of the impeller in the passage, enhancing an ability of discharging a surging-occuring range to a lower flow rage. The compressor casing may be divided into a casing main body and an inner casing so as to decrease fabrication cost of the compressor casing.
