PROBLEM TO BE SOLVED: To provide a highly reliable enclosed compressor which prevents damage at the initial startup thereof by suppressing the evaporation amount of assembling oil. SOLUTION: A content ratio of a low boiling component can be controlled by employing assembling oil 126 in which kinetic viscosity at 40°C is between 3 mm<SP>2</SP>/s or higher and lower than 10 mm<SP>2</SP>/s and a content ratio of a boiling component having a distilling temperature of 400°C or lower is 70 vol.% or lower. By this, the evaporation amount when heating assembling oil can be reduced to secure the lubricity of a sliding part. As a result, the lubricity on the initial startup can be secured to obtain a highly reliable enclosed compressor. COPYRIGHT: (C)2010,JPO&INPIT |
