Title:
SCROLL COMPRESSOR AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2023/063243
Kind Code:
A1
Abstract:
A cylindrical main shell (11) that houses a compression mechanism unit (3) having a fixed scroll (31) and an orbiting scroll (32), a frame (2) for slidably holding the orbiting scroll (32), and a drive mechanism unit (4) for sliding the orbiting scroll (32) is composed of a first straight tube section (1111) extending along the central axis, a second straight tube section (1112) having a smaller outer diameter than the first straight tube section (1111), and a third straight tube section (1113) having a smaller outer diameter than the second straight tube section (1112). Due to the outer diameter (D3) of the third straight tube section being reduced, the main shell (11) can be kept from breaking even when the ratio between the outer diameter (D1) of the first straight tube section and the outer diameter (D3) of the third straight tube section of the main shell (11) exceeds a strain amount equivalent to the tensile strength of the material forming the main shell (11).
