Abstract (en)

[origin: EP1770341A2] An object is to provide a refrigerant compressor which solves a disadvantage that an oil flows into a refrigerant circuit in the outside of the refrigerant compressor during introduction of the oil and which minimizes an amount of the oil to be introduced and which can secure a sufficient amount of the oil, and a refrigerant cycle device including the refrigerant compressor. A rotary compressor (refrigerant compressor) comprises, in a sealed container (12), an electromotive element (14) as a driving element, and a rotary compression mechanism part (18) driven by this electromotive element (14) and constituted of first and second rotary compression elements (32,34), and discharges a refrigerant compressed by the rotary compression mechanism part (18) from the sealed container, the compressor further comprising an oil reservoir (80) constituted in a bottom part of the sealed container; and a servicing pipe (100) attached to the sealed container to introduce the refrigerant and the oil into the sealed container.
