Abstract:
1. A hermetic compressor comprising: a casing including a high pressure chamber, an intake pipe and a discharge pipe, the intake pipe supplying a refrigerant to the casing from an outlet of an evaporator, and the high pressure chamber communicating with the discharge pipe to supply high pressure refrigerant to a condenser; a compression mechanism accommodated within the casing for sucking the refrigerant from the intake pipe, compressing the refrigerant, and discharging the refrigerant into the high pressure chamber, which contains lubricant oil at a bottom of the high pressure chamber that is supplied to the compression mechanism, a container member being a separate body from and communicating with a bottom part of the high pressure chamber so as to allow the lubricant oil to flow to and from the container member; and a pressure reduction device which sucks gas refrigerant in the container member and sends out the thus sucked gas refrigerant to the intake pipe for reducing an inside pressure of the container member, the pressure reduction device being in fluid communication with the intake pipe at a location between the outlet of the evaporator and an inlet of compression mechanism.
