Document Type and Number:
WIPO Patent Application WO/2018/034273
Kind Code:
A1
Abstract:
The present invention provides a scroll compressor that makes it possible to achieve three-dimensional compression without the use of stepped sections like those of a stepped scroll compressor. The scroll compressor (1) is provided with a fixed scroll member (3) and a rotating scroll (5). The scroll compressor (1) is also provided with an inclined section in which the distance (L) between the facing surfaces of an end plate (3a) and an end plate (5a) that face each other continuously decreases from the outer circumferential side toward the inner circumferential side. The inclined section is configured from wall body inclined sections (3b1, 5b1) in which the heights of wall bodies (3b, 5b) decrease continuously from the outer circumferential side toward the inner circumferential side and end plate inclined sections (3a1, 5a1) in which tooth bottom surfaces are inclined in accordance with the inclines of the wall body inclined sections (3b1, 5b1).
