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.

摘要： A refrigeration cycle apparatus includes an expander-compressor unit (1) having a first motor (12), a second compressor (2) having a second motor (22), and a controller (7). The controller (7) determines the target rotational frequency F1 of the first motor (12) and the target rotational frequency F2 of the second motor (22) for a start-up operation, and determines whether the opening X of an injection valve (61) should be in a fully opened state or in a fully closed state during the start-up operation, based on an outside air temperature and other factors. Then, the controller (7) performs the start-up operation by controlling the rotational frequencies f1 and f2 of the first motor and the second motor to be the determined target rotational frequencies F1 and F2 while maintaining the opening X of the injection valve in the fully opened state or in the fully closed state.

摘要： An expander-integrated compressor 200A includes a closed casing 1, a compression mechanism 2, an expansion mechanism 3, a shaft 5, an oil pump 6, and a heat insulating structure 30A. The oil pump 6 is disposed between the compression mechanism 1 and the expansion mechanism 3, and draws, via an oil suction port 62q, an oil held in an oil reservoir 25 to supply it to the compression mechanism 2. The heat insulating structure 30A is disposed between the oil pump 6 and the expansion mechanism 3, and limits a flow of the oil between an upper tank 25a, in which the oil suction port 62q is located, and a lower tank 25b, in which the expansion mechanism 3 is located, so as to suppress heat transfer from the oil filling the upper tank 25a to the oil filling the lower tank 25b.

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： A refrigeration cycle apparatus 100 includes a compressor 2, a radiator 3, a positive displacement fluid machine 4, an evaporator 7, an injection flow passage 10f and a controller 102. The positive displacement fluid machine 4 performs a step of drawing a refrigerant, a step of expanding and overexpanding the drawn refrigerant, a step of supplying, through an injection port 30, the refrigerant to a working chamber so as to mix the supplied refrigerant with the overexpanded refrigerant, a step of recompressing the mixed refrigerant by using power recovered from the refrigerant, and a step of discharging the recompressed refrigerant. The controller 102 executes an activation control for allowing a pressure in the injection flow passage 10f to be a pressure equal to an outlet pressure of the compressor 2 at time of activation of the refrigeration cycle apparatus 100.

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).

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 high 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.
