An axial flow compressor includes: an electric motor including a rotating shaft; a compression portion including a driving shaft connected without a speed-up gear to the rotating shaft of the electric motor and a rotor rotating together with the driving shaft, the compression portion driving the driving shaft and thereby compressing a working fluid; and a velocity reducing portion having a space for reducing the flow velocity of a working fluid discharged from a discharge opening of the compression portion. The rotating shaft of the electric motor is connected to the end of the driving shaft on the side of the discharge opening; and the velocity reducing portion is disposed so as to surround the electric motor.

Axial flow compressor

An axial flow compressor includes: a rotor having a rotor vane; a first pressing member joined to one end surface of the rotor; a second pressing member joined to the other end surface of the rotor; a rotor shaft portion penetrating the first pressing member, the rotor and the second pressing member; and a nut which fixes the first pressing member and the second pressing member on the rotor shaft portion with the first pressing member and the second pressing member holding the rotor between. The rotor shaft portion is made of a material having a lower linear expansion coefficient than that of a material making at least a part of the rotor. The material making at least a part of the rotor may be aluminum or aluminum alloy.

A compressor and a refrigerating machine which enable an easy disposal of a lubricant, are friendly to the natural environment, and have simple configurations, are provided. The compressor which is used in a refrigerating machine including an evaporator and a condenser and adapted for compressing refrigerant gas evaporated in the evaporator to convey the compressed refrigerant gas to the condenser, includes: a motor; a housing having a compression chamber inside; a rotary member which has a rotating shaft and is rotated by a driving force of the motor so as to compress water vapor serving as the refrigerant gas in the compression chamber; a bearing for supporting the rotating shaft of the rotary member in the housing; and a lubricant supplier for supplying water serving as a lubricant to the bearing.
