Embodiment 1
[0033] This embodiment takes a scroll compressor as an example to illustrate the implementation of the sealing structure according to the present invention. In addition to the scroll compressor, the present invention can be applied between relatively stationary shells, covers, plates and other parts. , especially on instruments with high sealing requirements due to the pressure difference between the cavity and the atmosphere.
[0034] Such as picture 1 As shown, the compression assembly of the scroll compressor includes a movable scroll 53 and a fixed scroll 52 , which mesh with each other to enclose a plurality of compression chambers 54 . The fixed scroll 52 remains stationary, and the movable scroll 53 is driven by the crankshaft 55 to rotate eccentrically. The peripheral compression chamber 54 sucks the refrigerant, and the compression chamber 54 gradually moves to the center while shrinking in size. When it moves to the center, the refrigerant is discharged, thereby ...
