ABSTRACT:
A centrifugal compressor for a small-sized gas turbine utilized in an automobile. In a general gas turbine having a centrifugal compressor, a primary air flow along the front surface of a rotor disc is joined by a secondary air flow from a space between the rear surface of the rotor disc and a partition wall in an engine casing. The present invention provides improved positional relationships between the forward end of the outer periphery of a rotor disc and the rear wall of a diffuser, the outer periphery of the rotor disc and the tip of a rotor blade and the shape of the rear surface of the outer periphery of the rotor disc and the shape of the wall of a partition wall in an engine casing being opposed thereto, and a combination of those relationships to prevent the secondary air flow from changing the direction of the primary air flow.
