Description

Technical Field

[0001] The utility model relates to the technical field of compressors, in particular to a piston ring pressing ring tooling. Background Art

[0002] A compressor is a driven fluid machine that boosts low-pressure gas to high-pressure gas. It is the heart of the refrigeration system.
