    • Disclosed is a hermetic compressor which has a simplified structure and can adequately separate a coolant from a lubricating oil, and efficiently discharge the coolant to the exterior of a hermetic container. A discharge passage (90) is provided either within a scroll unit (30) and a main shaft frame (14) or between the inner wall surface of a drum portion (3) of a hermetic container (2) and the scroll unit and the main shaft frame in such a way as to conduct the coolant and lubricating oil directly to a stator (8) of an electric motor (6). An oil-separation plate (96) for separating the lubricating oil from the coolant conducted from a discharge passage is provided at the top of the stator, and a discharge pipe (72) for discharging the coolant from which the lubricating oil has been separated to the exterior of the hermetic container is provided in the drum portion arranged below the main shaft frame.
    • 本发明公开了一种密闭型压缩机,其结构简单,能够使冷却液与润滑油充分分离,并将冷却液有效地排出到密闭容器的外部。 在涡旋单元(30)和主轴框架(14)内或者在密封容器(2)的鼓部分(3)的内壁表面和涡旋单元之间设置排放通道(90) 主轴框架上,以便将冷却剂和润滑油直接导入电动机(6)的定子(8)。 用于从排放通道传导的冷却剂中分离润滑油的油分离板(96)设置在定子的顶部,以及排放管(72),用于将已经分离出润滑油的冷却剂排放到 密封容器的外部设置在布置在主轴框架下方的鼓部中。
