wherein the inlet guide vane is provided at the suction port into which the fluid is drawn by rotation of the impeller and wherein the inlet guide vane is turnably installed about an axis line at the suction port in order to adjust a suction amount and flow direction of the fluid.
3. A refrigerator comprising:
a condenser that cools and liquefies a compressed refrigerant;
an evaporator that takes heat of evaporation away from a cooling object to cool the cooling object by evaporating the liquefied refrigerant; and
a compressor that compresses the refrigerant evaporated by the evaporator and supplies the refrigerant to the condenser, the compressor being a compressor that compresses a fluid with a compression mechanism that has an impeller and a diffuser and is capable of supplying the compressed fluid to a condenser, the compressor comprising,
an inlet guide vane that is turnably installed about an axis line at a suction port into which a fluid is drawn by rotation of the impeller in order to adjust a suction amount and flow direction of the fluid, the inlet guide vane comprising:
a shaft that is turnably supported by inserting a round bar-shaped shaft main body portion thereof in a bearing sleeve; and
a plate-shaped vane main body that is joined with the shaft and projects from an inner periphery surface of the suction port to a central portion of the suction port,
the shaft including a flange portion that is provided at a distal end side in a direction of the axis line to join with the vane main body and that extends to an outside in a direction perpendicular to the axis line so as to be extended outward in a radial direction of the bearing sleeve.
4. The refrigerator according to claim 3, wherein a width of the flange portion in the direction perpendicular to the axis line is a size of at least 1.5 times an outer diameter of the shaft main body portion andor at least \u2153 of a maximum width of the vane main body.
