摘要： An expander-compressor unit (10) includes a two-stage rotary expansion mechanism (3) having a first cylinder (41) and a second cylinder (42). In the expansion mechanism (3), a suction port (71) facing a working chamber on the upstream side in the first cylinder (41) and a discharge port facing a working chamber on the downstream side in the second cylinder (42) are formed. An intermediate plate (43) is provided between the first cylinder (41) and the second cylinder (42). In the intermediate plate (43), a communication passage (43a) for allowing communication between a working chamber on the downstream side in the first cylinder (41) and a working chamber on the upstream side in the second cylinder (42) is formed. The communication passage (43a) does not communicate with the working chamber in the first cylinder (41) during the suction process, and communicates with the downstream working chamber in the first cylinder (41) at or after the end of the suction process.

摘要： An expander-integrated compressor (5A) has a compression mechanism (21) for compressing a refrigerant and an expansion mechanism (22) for expanding the refrigerant. The compression mechanism (21) is located above the expansion mechanism (22) inside a closed casing (10) and shares a rotating shaft (36) with the expansion mechanism (22). An oil pump (37) is provided at the lower end of the rotating shaft (36). The oil pump (37) is immersed in oil in an oil reservoir (15). Usually, the oil is placed in the oil reservoir (15) in such a manner that the oil level (OL) is located above a lower end portion (34e) of a vane (34a) of a first expansion section (30a). More preferably, the oil is placed in such a manner that the expansion mechanism (22) is immersed in the oil. An oil supply passage (38) for guiding the oil to the compression mechanism (21) is formed inside the rotating shaft (36). A suction port (37a) of the oil pump (37) is provided below the lower end portion (34e) of the vane (34a).

摘要： A multi-stage rotary-type fluid machine may be configured as what is called a two-stage rotary expander, in which a refrigerant expands in an expansion chamber having a first discharge side space (115b) of a first cylinder (105), a second suction side space (116a) of a second cylinder (106), and a communication hole (104a) for allowing communication between the two spaces (115b, 116a). The first cylinder (105) and the second cylinder (106) are partitioned by an intermediate plate (104). The communication hole (104a) is formed so as to penetrate through the intermediate plate (104). The opening shape and location of the communication hole (104a) are set so that direct blow-through of the refrigerant from a suction port (105b) to a discharge port (106b) cannot occur at any rotation angle of a shaft (103).
