摘要： PROBLEM TO BE SOLVED: To enlarge the actuation range of a centrifugal compressor used for a compressed air feeder such as a compressor for a turbocharger or an industrial compressor.
SOLUTION: In a circulation flow path 6, there are formed fourth circulation flow path parts 16 located at two appropriate positions of the inner peripheral surface of a casing 2 and a third circulation flow path part 17. The circulation flow path 6 is constituted with an inner surface 12 and an outer surface 11. Local curved surfaces are formed on the inner surface 12 and the outer surface 11 of the circulation flow path 6 to thereby increase the circulation flow rate. As a result, a decrease in the surging flow rate or an increase in the choking flow rate is promoted so as to enlarge the actuation range.

摘要： PROBLEM TO BE SOLVED: To provide an electric appliance capable of globally suppressing nonuniform thermal conduction. SOLUTION: The electric appliance comprises a stator (1), a rotor (6) that rotates by magnetic interaction received from the stator (1), and a case (2) that covers the stator (1). In the stator (1) or the case (2), through-holes (1a, 2a) are formed which penetrate the stator (1) or the case (2) and spirally extend around a rotating shaft of the rotor (6). A cooling medium (10) for cooling the stator (1) flows to the through-holes (1a, 2a). The flow of the cooling medium (10) is not rectified, since the cooling medium (10) spirally flows to the stator (1), and thus nonuniform thermal conduction is suppressed globally in the electric appliance.
