摘要： PROBLEM TO BE SOLVED: To provide a refrigerant compressor capable of continuing an operation by preventing entering of open air inside a housing even under a condition that an inlet pressure becomes a negative pressure below the atmospheric pressure.
SOLUTION: In the refrigerant compressor 1 where one end of a drive shaft 6 is connected to a compression mechanism 15 and the other end projects outside while penetrating a housing 2, the compressor is constituted so as to be driven by an external driving source, and is provided with a lip seal 11 for sealing a portion between the open air and an inlet side space 25 at a place where the drive shaft 6 of the housing 2 penetrates. In the housing 2, a lip sealing chamber 27, which is divided from the inlet side space 25 by a dividing means 26, is formed at the side of compression mechanism 15 from a lip sealing 11, and in the lip sealing chamber 27, a gas introducing path 28 is provided from which a refrigerant gas with an intermediate pressure, which is higher than the atmospheric pressure and lower than the discharge pressure, is introduced.
