Abstract (en)

[origin: EP3434902A1] Provided are a hermetic rotary compressor configured so that the pressure resistance of a hermetic case is increased and so that the hermetic case will not become large, and a refrigeration cycle device provided with the hermetic rotary compressor. A hermetic case (10) is provided with a main case (10a) and an end case (10c) which is fitted in the main case (10a). A first compression mechanism (18A) is provided with a first cylinder (21). A second compression mechanism (18B) is provided with a second cylinder (22). The entire first cylinder (21) is accommodated within the main case (10a) in the axial direction of a rotating shaft (13). At least a part of the second cylinder (22) is inserted in the end case (10c). The maximum distance L from the center of the rotating shaft (13) to the outer periphery of the first cylinder (21) is greater than the maximum distance M from the center of the rotating shaft (13) to the inner periphery of the end case (10c).
