Claims

[Scope of utility model registration request]

An annular hollow chamber is provided inside a stationary partition wall that partitions the internal passage on the inlet side and the outlet side of the impeller so as to communicate with the internal passage on the outlet side or the outlet side of the impeller at a later stage, and a wall of the annular hollow chamber. An appropriate number of first holes are formed in the section so as to communicate with the internal passage on the input side.
The same number of second through holes are formed in the same positional relationship as the through holes and each of the first through holes, and the second through holes are slidably abutted against the wall surface on the first through hole side of the annular hollow chamber, A turbo compressor characterized in that a flow rate adjustment ring is provided in which the opening area of each of the second through holes can be adjusted simultaneously.
