Title:
SCROLL COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2022/239679
Kind Code:
A1
Abstract:
A scroll compressor 100 according to the present disclosure includes: a partition plate 120 that partitions the interior of a sealed container 110 into a high-pressure space 230 and a low-pressure space 240; and a compression mechanism unit 130 disposed in the low-pressure space 240. On the periphery of a fixed scroll 150 of the compression mechanism unit 130, an injection adapter 190 that is a separate body from the fixed scroll 150 and is capable of moving in an axial direction with respect to the fixed scroll 150 is provided. The injection adapter forms an in-adapter injection passage 191 without restricting the movement in the axial direction of the fixed scroll 150. Due to this configuration, the cross-sectional area of the in-adapter injection passage 191 can be enlarged, and a sufficient injection flow rate can be obtained. Moreover, performance improvements due to injection and discharge temperature reduction effects can be realized at a high level.
