Beschreibung
Zusammenfassung:	A compressor includes a first-stage compression unit configured to compress a refrigerant, a second-stage compression unit configured to compress the refrigerant compressed by the first-stage compression unit, a shaft member connected to the first-stage compression unit and the second-stage compression unit, and a cover member configured to cover the shaft member. A first passage is provided between the first-stage compression unit and the second-stage compression unit. A front chamber is provided around the cover member. The front chamber is connected to the first passage and to a second passage to which the refrigerant from an economizer is sent. The second passage is provided with a passage structure configured such that a flowing direction of the refrigerant supplied through the second passage to the front chamber is an avoidance direction. The avoidance direction is a direction that differs from a direction toward the shaft member.
