HIGH EFFICIENCY PISTON RING |
摘要 |
Improved liquid lubricated piston ring gas seals with reduced friction and wear compared to prior art rings are disclosed for use in internal combustion engines, gas pumps and gas compressors. These improved rings allow independent adjustment of the parameters controlling friction and wear, and eliminate the tradeoff between low friction and low wear typical of prior art rings.
