Abstract

A compressor includes a casing, an electric motor housed in an internal space of the casing, a drive shaft rotated by the electric motor, and a compression mechanism driven by the drive shaft discharge compressed refrigerant to the internal space. The internal space includes a first and second spaces formed near axial ends of the electric motor. The electric motor includes a stator and a rotating member. The stator is fixed to the casing. The rotating member includes a rotor rotatably inserted into the stator. The electric motor has a refrigerant flow path through which the first and second spaces communicate with each other. The refrigerant flow path includes a first flow path into which the refrigerant in the first space or the second space flows, and a rotor flow path extending axially across the rotor and connected to an outflow end of the first flow path.
