Abstract
A scroll compressor (100) comprises an orbiting scroll component (160); a fixed scroll component (150); sealing components (PS1, PS2, PS3, PS4, PS5, PS6), wherein the sealing components match a concave part (158) on the orbiting scroll component (50) so as to form a back pressure chamber (BC) together, and the sealing components are constructed to separate the back pressure chamber from a high-pressure side and a low-pressure side in the scroll compressor (100); and a leakage path (L), wherein the leakage path (L) is constructed to allow fluid in the back pressure chamber (BC) to leak.
