Zusammenfassung:A compressor includes a first-stage compression unit (110), a second-stage compression unit (120), a shaft member (130) connected to the first-stage compression unit (110) and the second-stage compression unit (120), and a cover member (171) configured to cover the shaft member (130). A first passage (140) is provided between the first-stage compression unit (110) and the second-stage compression unit (120), and a front chamber (180) is provided around the cover member (171). The front chamber (180) is connected to the second passage (150), and the second passage (150) is provided with a passage structure configured such that the flowing direction of the refrigerant supplied through the second passage (150) to the front chamber (180) is an avoidance direction that is a direction different from a direction toward the shaft member (130).
