GAS-DISTRIBUTING MECHANISM

摘要

FIELD: engines and pumps.SUBSTANCE: gas-distributing mechanism of ICE includes valves with heads and shafts, which are located in movable manner in guide sleeves of head of ICE cylinder block. In shaft there made are longitudinal vertical channels and transversely located holes. The latter are arc-shaped and have variable cross section throughout their length. Larger diameters of holes are conjugated with vertical channels, and smaller diameters are located in contact zone with guide sleeves of valves. Vertical channels of shafts have variable cross section, which is smoothly transient from cylindrical hyperboloid to some part of single-cavity hyperboloid.EFFECT: improving reliability of gas-distributing mechanisms of ICE.2 dwg
