no. 1 approach
[0028] Such as figure 1 As shown, the cascade vane compressor of the first embodiment has a first side plate 11, a first cylinder block 5, a second side plate 13, a second cylinder block 7 and a third side plate 15, and the first side plate 11 , the first cylinder block 5 , the second side plate 13 , the second cylinder block 7 , and the third side plate 15 are fixed in a state received in the front case member 1 and the rear case member 3 coupled to each other. The front housing member 1 and the rear housing member 3 form an outer shell 9 . The diameter of the casing 9 is the same as that of the single-cylinder type vane compressor. Furthermore, the first cylinder block 5 and the second cylinder block 7 have the same outer shape.
[0029] Such as figure 2 As shown, an elliptical first cylinder chamber 5 a in a direction perpendicular to the axis is also formed in the first cylinder block 5 . Such as image 3As shown, a second cylinder chamber 7a having the same shape as...
no. 2 approach
[0065] In the cascade vane compressor of the second embodiment, as Figure 4 As shown, a main upstream passage 11h is formed in the first side plate 11 to extend upward from the lower end. Furthermore, in the first side plate 11 is formed an annular main intermediate passage 11 i surrounding the shaft hole 11 a. The upper end of the main upstream passage 11h communicates with the main intermediate passage 11i. Furthermore, in the first side plate 11, two main downstream passages 11j for communicating with the main intermediate passage 11i extend rearward in the axial direction. The respective main downstream passages 11j are configured to communicate with the main back pressure chamber 33 during compression and during discharge by the rotation of the first rotor 27. The main upstream channel 11h, the main intermediate channel 11i, the main downstream channel 11j form a first supply channel.
[0066] Furthermore, similarly to the first embodiment, a second supply passage com...
no. 3 approach
[0072] In the cascade vane compressor of the third embodiment, as Figure 5 As shown, a sub-upstream passage 13p is formed in the second side plate 13 to extend upward from the lower end. Further, in the second side plate 13, a sub-middle passage 13q surrounding the shaft hole 13a is formed. The upstream end of the sub-upstream passage 13p communicates with the sub-intermediate passage 13q. Furthermore, in the second side plate 13, two sub-downstream passages 13r for communicating with the sub-middle passage 13q extend rearward in the axial direction. The respective sub-downstream passages 13r are configured to communicate with the sub-back pressure chamber 39 during compression and during exhaust by the rotation of the second rotor 29 . The sub-upstream passage 13p, the sub-middle passage 13q, and the sub-downstream passage 13r form a second supply passage.
[0073] Furthermore, similarly to the second embodiment, a first supply passage configured by the main upstream pass...
