Abstract

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.

Description

technical field [0001] The present invention relates to a refrigerant compressor equipped with a drive unit and a compression unit driven by the drive unit in an airtight container, and to discharge the refrigerant compressed by the compression unit to the outside of the airtight container, and a refrigeration compressor equipped with the refrigerant compressor. Agent circulation device. Background technique [0002] Conventionally, such a refrigerant cycle device including a refrigerant compressor constitutes a refrigerant circuit by sequentially connecting a refrigerant compressor, a radiator, a capillary tube (throttling mechanism), an evaporator, and the like in an annular manner. Such a refrigerant compressor is configured, for example, in a rotary compressor including a drive unit and a rotary compression unit driven by the drive unit in an airtight container, and refrigerant gas is sucked into the drive cylinder from the suction port of the rotary compression unit. T...
