Document Type and Number:
WIPO Patent Application WO/2019/176014
Kind Code:
A1
Abstract:
The purpose of a compressor according to the present invention is to provide a compressor which has a reduced internal volume while ensuring an electric insulation distance between an electric motor and a compression mechanism and inhibiting outward drawing of lubricating oil by a refrigerant discharged from the compressor. The compressor according to the present invention is provided with: a compression mechanism which compresses a refrigerant; an electric motor part which is disposed above the compression mechanism and which drives the compression mechanism; a shell in which the compression mechanism and the electric motor part are housed; and a lower insulation member disposed between the compression mechanism and the electric motor part. The electric motor part is provided with: a stator fixed to the shell; and a rotor disposed at a predetermined distance away from the inner circumferential surface of the stator. The rotor is provided with a rotor path that connects upper and lower spaces of the electric motor part, and the lower insulation member is disposed in a region on the outer circumferential side relative to the inner circumferential surface of the stator.
