Abstract

A compressor (1) including a hermetic housing (2), a low stage-side compression mechanism (3) and a high stage-side compression mechanism (4) provided in the hermetic housing (2); and an electric motor (21) for driving the low stage-side compression mechanism (3) and the high stage-side compression mechanism (4). The low stage-side compression mechanism (3) is a rotary type compression mechanism, and the high stage-side compression mechanism (4) is a scroll type compression mechanism. The suction shutoff of the scroll type compression mechanism is accomplished when a rotor (34) of the rotary type compression mechanism is at a position (A) corresponding to the bottom dead center, at a position (B) of being rotated through 90 degrees from the bottom dead center, or between the positions (A and B).
