Embodiment approach 1
[0018] Figure 1 to Figure 6 is a diagram showing Embodiment 1, figure 1 is a longitudinal sectional view of the twin-cylinder rotary compressor 100, figure 2 and image 3 is a longitudinal sectional view of the compression mechanism part 3 of the two-cylinder rotary compressor 100, Figure 4 yes figure 2 The Z-Z section view in, Figure 5 It is a figure showing the procedure of assembling the first piston 11a to the crankshaft 4 when the relief shape 11a-1 is provided at both axial ends of the inner diameter of the first piston 11a, Figure 6 is a comparison Figure 5 and Figure 7 of the graph ( Figure 6 (a) represents a comparative example, Figure 6 (b) represents this embodiment).
[0019] Below, use Figure 1 to Figure 6 The twin-cylinder rotary compressor 100 according to Embodiment 1 will be described.
[0020] use figure 1 The configuration of the two-cylinder rotary compressor 100 will be described. A motor 2 including a stator 2 a and a rotor 2 b and...
Embodiment approach 2
[0080] In Embodiment 1, the relationship between the inner diameter 10 a of the separator 10 and the first piston 11 a and the second piston 11 b is not particularly mentioned. The inner diameter 10 a of the separator 10 and the first piston 11 a and the second piston 11 b may be formed in, for example, the following relationship. In addition, items that are not particularly described in the second embodiment are the same as those in the first embodiment, and the same functions and configurations will be described using the same reference numerals.
[0081] Figure 8 It is a figure which shows Embodiment 2, and is a longitudinal cross-sectional view of the compression mechanism part 3 of the twin-cylinder rotary compressor 100. As shown in FIG.
[0082] Such as Figure 8 As shown, if the distance from the axial center of the intermediate shaft 4e to the inner peripheral surface of the inner diameter 10a of the separator 10 (that is, the radius of the inner diameter 10a of th...
