Claims

[Scope of utility model registration request]

A multi-stage compression section is formed by arranging an outer circumferential partition plate and an inner circumferential partition plate facing each other along the axial direction of the rotating shaft, and the fluid to be compressed is transferred between the partition plates to the subsequent compression section. In a multi-stage compressor having an annular return passage, an outer partition plate is formed that butts against each other from both sides of the inner partition plate to partition an outer circumference of the return passage, and is attached to the outer circumference of the abutting portion. A support guide member is formed along the axial direction so as to surround the support guide member, and the outer circumferential side partition plate and the inner circumferential side partition plate are faced to each other and fixed by pressing from one direction. Multi-stage compressor.
