Piston rings? No problem New piston rings for refrigeration compressors

Abstract

Reliable, durable and economical operation of reciprocating refrigeration compressors, as well as automobile engines, depends on the performance properties of components and parts. The most important parts of the piston mechanism are sealing and oil scraper rings, which prevent the leakage of compressed gas into the crankcase and the removal of lubricating oil into the compression cavity.
These rings must have high wear resistance and low coefficient of friction, quickly run in and prevent active wear of cylinder liners.
