PROBLEM TO BE SOLVED: To prevent, in a horizontal electrically driven gas compressor 1, occurrence of an operational failure of a gas compression mechanism 30 due to a shortage of lubricant caused by accumulation and stagnation of lubricant and liquefied refrigerant in the space at the bottom of a suction chamber 11 even in a low-speed operation state.SOLUTION: The electrically driven gas compressor includes: an electric motor 20 disposed within the suction chamber 11 of the housing 2; the gas compression mechanism section 30 disposed within the housing 2 and operated by the electric motor 20; a sucked refrigerant guide path 60 for guiding to the gas compression mechanism section 30 a refrigerant within the suction chamber 11; and a lubricant supply path 65 for connecting, at the bottom of the suction chamber 11, the suction chamber 11 and the sucked refrigerant guide path 60 in order to supply the lubricant, which is accumulated and stagnated in the space at the bottom of the suction chamber 11, to the inside of the sucked refrigerant guide path 60. The lubricant accumulated in the space at the bottom of the suction chamber 11 is supplied to the inside of the sucked refrigerant guide path 60 by the weight of the oil itself, that is, the lubricant can be supplied independent of the rotational speed. |
