摘要： An object of the present invention is to enable a reduction in weight and improve reliability. A rotary compressor (101) has a cylinder (24), a piston (21), and a bushing (22). The cylinder (24) includes a cylinder hole (24a). The piston (21) moves relative to the cylinder (24) in the cylinder hole (24a). The bushing (22) slides against the cylinder (24) and the piston (21) in the cylinder hole (24a). The cylinder (24) and the piston (21) are formed from an Al-Si alloy having a Si content exceeding 12.6 wt%, which is a eutectic point. The bushing (22), which is formed from steel, has a surface layer including a sliding surface (22a) that slides against the cylinder (24) and the piston (21). The surface layer is reformed so as to have greater hardness than hardness of proeutectic Si contained in the Al-Si alloy. The surface layer also has hardness of at least Hv 1000 in the sliding surface.

摘要： An air-conditioning apparatus (1) comprises a four-stage compressor (2), switching mechanisms (31 to 33), intercoolers (51 to 53), oil separators (41 to 43), and a control unit. The four-stage compressor (2) has four compression mechanisms (21 to 24) connected in series. The switching mechanisms (31 to 33) are connected to blow-out pipes (101b to 103b) of the compression mechanisms (21 to 23). The switching mechanisms (31 to 33) switch between a cooling operation cycle and a heating operation cycle. The intercoolers (51 to 53) cool a refrigerant blown out from the compression mechanisms (21 to 23) during the cooling operation cycle. The oil separators (41 to 43) are placed between the switching mechanisms (31 to 33) and the intercoolers (51 to 53). The oil separators (41 to 43) separate a lubricating oil from the refrigerant blown out from the compression mechanisms (21 to 23) during the cooling operation cycle. A control unit controls the four-stage compressor (2) and the switching mechanisms (31 to 33).

摘要： In a refrigerant circuit (5) of an air conditioner (1), a single-stage compression refrigeration cycle is performed. In the refrigerant circuit (5), a second heat exchanger (40) is provided downstream a first heat exchanger (30). In the first heat exchanger (30), high-pressure refrigerant of a high-pressure flow path (31) is cooled by exchanging heat with first intermediate-pressure refrigerant of an intermediate-pressure flow path (32). First intermediate-pressure gas refrigerant generated in the first heat exchanger (30) is supplied to a first compression mechanism (71). Second intermediate-pressure refrigerant having a pressure lower than that of the first intermediate-pressure refrigerant is supplied to an intermediate-pressure flow path (42) of the second heat exchanger (40). In the second heat exchanger (40), high-pressure refrigerant of a high-pressure flow path (41) is further cooled by exchanging heat with the second intermediate-pressure refrigerant of the intermediate-pressure flow path (42). Second intermediate-pressure gas refrigerant generated in the second heat exchanger (40) is supplied to a second compression mechanism (72).

摘要： In two compression units (41, 51) of a compressor, phases of respective pistons (45, 55) are configured to be opposite to each other. The piston (45, 55) has a non-circular outer peripheral surface, whereas a cylinder chamber (60, 70) has an inner peripheral surface of which shape is determined based on an envelope of the outer peripheral surface of the piston (45, 55) in rotation. The compressor includes an introduction section (67, 68, 163a, 164a) configured to introduce an intermediate-pressure refrigerant into a compression chamber (75) of the compression unit (41, 51).

摘要： In a positioning apparatus (40), a fixed scroll (34) is positioned with respect to an assembly body (11) in which a compressor motor (25) has been incorporated. In positioning the fixed scroll (34), electric power is supplied to the compressor motor (25) from an inverter (81) to rotate a crank shaft (20) by the compressor motor (25), thereby shifting a movable scroll (31). In the positioning apparatus (40), the shift of the movable scroll (31) leads to calculation of an appropriate position of the fixed scroll (34). A striking unit (70) applies impact force to the fixed scroll (34) to stir the fixed scroll (34) to the appropriate position.
