SLIDING COMPRESSOR ELEMENT, SLIDING ELEMENT BASE, SPIRAL ELEMENT AND COMPRESSOR Russian patent published in 2010 - IPC F04C29/00 C21D5/00 B22D27/00 

FIELD: engines and pumps.

SUBSTANCE: invention relates to development of sliding components used in compressors. Sliding component (17, 23, 24, 26, 39, 60, 96, 310b, 524, 526, 644, 646, 724, 726, 734, 736, 817, 821, 823, 824, 825, 826, 827, 921, 924) of compressor features content of carbon varying from 2.0 wt % to 2.7 wt %, content of silicon varying from 1.0 wt % to 3.0 wt %, the rest making iron that contains unavoidable impurities. Metal structure represents, mainly, perlitic structure, ferrite structure and grain graphite. Metal hardness exceeds HRB 90, but is smaller than HRB 100. Smaller part of sliding component has high tensile strength.

EFFECT: longer operating life, fast running-in, no jamming in abnormal conditions.
