用するようにしたことを特徴とする冷凍用圧縮機。An auxiliary tank 4 for storing lubricating oil is provided outside the main body casing 1 housing the refrigerant compression device 2, and the upper gas phase part IA in the main body casing 1 and the upper gas phase part 4A in the auxiliary tank 4 are connected in an upper part. Through the passage 5, the bottom oil phase part 1B in the main body casing 1 and the bottom oil phase part 4B in the auxiliary tank 4 are communicated with each other through the lower communication passage 6, and the bottom oil phase part 1B in the main body casing 1 is made to communicate with each other through the lower communication passage 6. Bottom oil phase part IB
While the total pressure P of the refrigerant gas G flowing in the main body casing 1 is applied to the oil level of the lubricating oil 10 stored in the auxiliary tank 4 during operation of the compressor, the bottom oil phase portion 4B of the auxiliary tank 4 is A refrigeration compressor characterized in that a refrigerant gas pressure P' lower than the total pressure P acts on the oil level L' of the lubricating oil 10' stored during compressor operation.
