Document Type and Number:
WIPO Patent Application WO/2022/000872
Kind Code:
A1
Abstract:
A scroll compression mechanism and a scroll compressor. The scroll compression mechanism comprises: a movable scroll (20); and a fixed scroll assembly comprising a fixed scroll (30, 30a, 30b) and a cover plate (100, 100a, 100b), the fixed scroll (30, 30a, 30b) comprising a fixed scroll end plate (32, 32a), and the cover plate (100, 100a, 100b) being fixed on one side of the fixed scroll end plate (32, 32a), so that a central high-pressure recess (36) capable of being in fluid communication with a central compression cavity is defined between the cover plate (100, 100a, 100b) and the fixed scroll end plate (32, 32a), and a back pressure cavity (70) is formed on the side of the cover plate (100, 100a, 100b) facing away from the fixed scroll (30, 30a, 30b); the fixed scroll assembly being further provided with a medium-pressure channel, the medium-pressure channel enabling a middle compression cavity to be in fluid communication with the back pressure cavity (70); a sealing reinforcing structure for limiting a sealing reinforcing area being provided between the cover plate (100, 100a, 100b) and the fixed scroll end plate (32, 32a); the medium-pressure channel penetrating through the sealing reinforcing area so as to prevent a working fluid from leaking from the central high-pressure recess (36) to the medium-pressure channel. According to the scroll compression mechanism, the wear failure of the scroll compression mechanism can be prevented, the service life of the scroll compression mechanism is prolonged, and the use performance of the scroll compression mechanism is improved.
