摘要： A sub-compressor (23) is provided between a compressor (22) and a power-recovery device (24). A refrigerant after preliminarily being compressed by the sub-compressor (23) is allowed to flow into the compressor (22). Since the sub-compressor (23) and the power-recovery device (24) have approximately the same temperature, heat transfer hardly occur therebetween. Heat transfer occurs between the compressor (22) at high temperature and the sub-compressor (23) at low temperature. However, even if the heat from the compressor (22) heats the refrigerant in the sub-compressor (23), the refrigerant discharged from the sub-compressor (23) is delivered to the compressor (22), and thus the temperature of the sub-compressor (23) scarcely increases.
摘要翻译：副压缩机（23）设置在压缩机（22）和动力回收装置（24）之间。预先由副压缩机（23）压缩后的制冷剂被允许流入压缩机（22）。由于副压缩机23和动力回收装置24具有大致相同的温度，因此几乎不发生热传递。在高温的压缩机22与低压的副压缩机23之间发生热传递。然而，即使来自压缩机（22）的热量加热副压缩机（23）中的制冷剂，从副压缩机（23）排出的制冷剂被输送到压缩机（22），因此，副压缩机（23）几乎不增加。

摘要： A refrigeration cycle apparatus 1 includes a refrigerant circuit in which a refrigerant circulates. The refrigerant circuit is formed by connecting in sequence a compressor 2 for compressing the refrigerant, a radiator 3 for allowing the refrigerant compressed by compressor 2 to radiate heat, a fluid pressure motor 4 as a power recovery means, and an evaporator 5 for allowing the refrigerant discharged by the fluid pressure motor 4 to evaporate. The fluid pressure motor 4 performs a process for drawing the refrigerant and a process for discharging the refrigerant. These processes are performed substantially continuously.

摘要： A fluid machine (101) includes a first compressor (107) and a second compressor (108). The first compressor (107) has a first closed casing (111), a first compression mechanism (102a), an expansion mechanism (104), and a shaft (113). A first oil reservoir (112) is formed in the first closed casing (111). The second compressor (108) has a second closed casing (125) and a second compression mechanism (102b). A second oil reservoir (126) is formed at a bottom portion in the second closed casing (125). The first closed casing (111) and the second closed casing (125) are connected to each other by an oil passage (109) so that a lubricating oil can flow between the first oil reservoir (112) and the second oil reservoir (126). An opening (109a) of the oil passage (109) on a side of the first closed casing (111) is located above the expansion mechanism (104) with respect to the vertical direction. This configuration prevents the low temperature lubricating oil in a surrounding space of the expansion mechanism (104) and the high temperature lubricating oil in the second compressor (108) from flowing. Thereby, the heat transfer between the first compressor (107) and the second compressor (108) is suppressed.

摘要： There may be a case where, by simply coupling the first compressor (expander compressor unit) and the second compressor with an oil-equalizing pipe, the first compressor is not lubricated sufficiently, thereby decreasing reliability. The volumetric capacity (V1) of the first available oil space (130) of the first compressor (101) is set larger than the volumetric capacity (V2) of the second available oil space (140) of the second compressor (102). With this configuration, even if the oil level (S1) of the first oil sump (13) decreases in transition to a state of steady operation, it is possible to maintain a sufficient amount of oil in the first compressor (101), and thus high reliability as a fluid machine can be achieved.

摘要： A refrigeration cycle apparatus (100) includes a first compressor (101), a second compressor (102), a radiator (4), an evaporator (6), and a pipe branching portion (30). The first compressor (101) has a first compression mechanism (1) and an expansion mechanism (5). The second compressor (102) has a second compression mechanism (2). The pipe branching portion (30) serves as a flow passage for introducing a refrigerant from the evaporator (6) to the first compression mechanism (1) and the second compression mechanism (2), respectively. The pipe branching portion (30) includes an inlet pipe (31) for receiving the refrigerant from the evaporator (6), a first branch outlet pipe (32) for introducing the refrigerant flowing into the inlet pipe (31) to the first compression mechanism (1), and a second branch outlet pipe (33) for introducing the refrigerant flowing into the inlet pipe (31) to the second compression mechanism (2). The inlet pipe (31) and the first branch outlet pipe (32) form an obtuse angle or an angle of 180° therebetween, and the inlet pipe (31) and the second branch outlet pipe (33) form an acute angle therebetween.

摘要： A rotary compressor (100) includes a compression mechanism (3), a motor (2), a suction path (14), a back-pressure chamber (18), a return path (16), an inverter (42), and a controller (44). A check valve (73) of a reed valve type for opening and closing a return port (3c) of the compression mechanism (3) is disposed in the back-pressure chamber (18). The return path (16) functions to return a working fluid to the suction path (14) from the back-pressure chamber (18). A volume-varying valve (17) is provided in the return path (16). The volume-varying valve (17) allows the working fluid to flow through the return path (16) when the suction volume of the compression mechanism (3) should be set relatively small, and precludes the working fluid from flowing through the return path (16) to increase the pressure in the back-pressure chamber (18) when the suction volume of the compression mechanism (3) should be set relatively large.
