Document Type and Number:
WIPO Patent Application WO/2023/286559
Kind Code:
A1
Abstract:
Provided is an annular sealing member for a compressor that is capable of exhibiting a reliable low-torque property without harming durability or causing deterioration of a sealing function. In a scroll compressor comprising a fixed scroll body 3, a movable scroll body 4, a shaft 7, a main bearing 9 that rotatably supports the shaft 7, and a main bearing member 12 that fixes the main bearing 9, wherein, together with a fluid being compressed in a compression chamber 5 by the rotation of the shaft 7 causing the movable scroll body 4 to revolve about the axis of the fixed scroll body 3, the fluid is supplied to a back pressure chamber 15a on the back surface side of the movable scroll body 4, this annular sealing member 16 is mounted to at least one annular groove 4d formed in the back surface of a bottom plate part 4a of the movable scroll 4, and seals the back pressure chamber 15a. In a ring side surface of the annular sealing member 16, a dynamic pressure groove is provided to at least a sliding surface that revolves and slides.
