NON-ROUND PISTON RING WITH VARIABLE DEGREE OF IRREGULARITY OF DISTRIBUTION OF RADIAL PARTIAL PRESSURES (VERSIONS)

摘要

FIELD: mechanical engineering; engines. ^ SUBSTANCE: proposed piston ring is mom-round. Ring gap in free state is within 11% and 18% of cylinder bore in which piston ring is installed. Degree of irregularity of distribution of radial partial pressure deltar is within -5.175333187 and +2.339517464. Irregularity of ring in gap area is from 1.3 to 1.9. Other design version of ring is described in invention also. ^ EFFECT: reduced vibration of rings, wear of friction parts, increase service life of engine. ^ 17 s dwg
