Abstract: A rotary compressor (102) has a shaft (4), a cylinder (5), a piston (8), a first vane (32), and a second vane (33). The first vane (32) divides a space between the cylinder (5) and the piston (8) along a circumferential direction of the piston (8). The second vane (33) further divides the space divided by the first vane (32) along the circumferential direction of the piston (8) so that a first compression chamber (25) and a second compression chamber (26) having a smaller volume than the first compression chamber (25) are formed within the cylinder (5). The piston (8) and the second vane (33) are integrated together, or the piston (8) and the second vane (33) are coupled together.

Abstract: A rotary compressor (102) has a shaft (4), a cylinder (5), a piston (8), a first vane (32), a second vane (33), a first suction port (19), and a second suction port (20). The first vane (32) divides a space between the cylinder (5) and the piston (8) along a circumferential direction of the piston (8). The second vane (33) further divides the space divided by the first vane (32) along the circumferential direction of the piston (8) so that a first compression chamber (25) and a second compression chamber (26) having a smaller volume than the first compression chamber (25) are formed within the cylinder (5). The first suction port (19) introduces a working fluid into the first compression chamber (25). The second suction port (20) introduces a working fluid into the second compression chamber (26). The second suction port (20) is provided with a suction check valve (50).

Abstract: An expander-integrated compressor (100) includes: a compression mechanism (2) for compressing a working fluid; an expansion mechanism (3) for expanding a working fluid; and a shaft (5) that couples the compression mechanism (2) and the expansion mechanism (3). The expansion mechanism (3) includes a variable vane mechanism (60). The variable vane mechanism (60) controls the movement of a first vane (48) so that the ratio of a period P2 to a period P1 (P2/P1) can be adjusted, where P1 denotes the period during which the first vane (48) is in contact with a first piston (46) in the course of one rotation of the shaft (5), and P2 denotes the period during which the first vane (48) is spaced from the first piston (46) in the course of one rotation of the shaft (5).

Abstract: A diameter of a main bearing member 12m is defined as Dm, a length thereof is defined as Lm, a diameter of the eccentric bearing member 11e is defined as De and a length thereof is defined as Le. A ratio (=Lm/Dm) of the length and the diameter of the main bearing member 12m and a ratio (=Le/De) of the length and the diameter of the eccentric bearing member 11e are set to Le/De?Lm/Dm?1. Therefore, contact at edge portions of both ends of the eccentric bearing member 11e does not occur, and it is possible to prevent contact at edge portions of both ends of the main bearing member 12m even if the main shaft 13m inclines, and to reduce a viscosity loss caused by oil 9a. Hence, the present invention provides a scroll compressor securing reliability of the bearing members 12m, 11e and 16s and having high efficiency.

Abstract: A rotary compressor 100 of the present invention includes a compression mechanism 3, a motor 2, a suction path 14, a communication passage 16 and an on-off valve 32 as a control mechanism 30. The rotary compressor 100 further includes an interior space 28, a first check valve 35a and a second check valve 35b. If the on-off valve 32 opens, a volume of the operation chamber 25 is reduced and with this reduction in the volume, the first check valve 35a opens. Pressure in the operation chamber 25 does not rise. At this time, the rotary compressor 100 is operated with substantially zero suction volume. If the on-off valve 32 is closed, the rotary compressor 100 is operated with a normal suction volume.

Abstract: The present invention provides a capacity-control refrigeration cycle device capable of efficiently vary capacity, and in any of a full operation mode in which capacity of the refrigeration cycle device is not controlled and an operation mode in which the capacity is controlled, all of refrigerants are discharged into a hermetic container 1 and then, the refrigerants pass through a discharge path 11 and are guided to outside of the hermetic container 1. After a refrigerant and oil are sufficiently separated in the hermetic container 1, the refrigerant is discharged to outside of the hermetic container 1. Therefore, efficiencies of a condenser 300 and an evaporator 600 are not deteriorated. Since it is possible to reduce an amount of oil taken outside of the hermetic container, it is possible to stably secure oil in an oil reservoir 22, and to prevent bite of parts of a compressing mechanism and to prevent abnormal wearing.
