COMPRESSOR

摘要

A compressor (1) that compresses a gas that flows in from the axial direction and discharges the gas in the radial direction or in a direction that is diagonal with respect to the axial direction includes: a rotating shaft (2); an impeller (3) that rotates together with the rotating shaft; and a compressor housing (6) that rotatably accommodates the impeller. The impeller includes: a hub (4) that is fixed to the rotating shaft and a plurality of main blades (5) that are provided so as to protrude from the hub. A leading edge (5b) of each of the main blades, when the impeller is viewed from the axial direction, at a position that is at least 50% of the length (L) of the blades that extend outward in the radial direction, is inclined to a rotation direction side with respect to the radial direction outward in the radial direction.
