特徴とする密閉形電動圧縮機。 In a hermetically sealed electric compressor in which an electric motor-driven compression mechanism having two cylinder mechanisms is housed in a hermetically sealed casing, a liquid injection circuit is connected only to one of the two cylinder mechanisms, and a first cylinder mechanism is connected to the first cylinder mechanism. A closed type cylinder mechanism is characterized in that a discharge gas passage is formed that communicates with the inside of the sealed casing through a discharge muffler chamber, while the other cylinder mechanism communicates with the first discharge muffler chamber through a second discharge muffler chamber. Electric compressor.
