Claims

[Scope of utility model registration request]

As a means for controlling the inflow angle of fluid into the impeller inducer section, a spiral channel is used to guide the fluid inward from the diffuser outlet, and a forward flow from the outlet of the spiral channel to the impeller inducer section is used. A centrifugal compressor characterized by being equipped with a slit-shaped fluid inlet that communicates with a passageway.
