Piston rings, английский
Used in engines to maintain a gas-tight seal between piston and cylinder, to assist in cooling the piston and to control cylinder wall lubrication; the three rings include a fire ring, a compression ring and an oil ring.
Phospate esters, английский
A class of synthetic esters with superior fire resistance; used primarily as fr fluids, they are formulated with these general properties: specific gravity greater than one, good lubricating capability, fair high-temperature stability, poor hydrolytic stability, and poor viscosity-temperature linkage. though they are harmful to paints and some seal materials, one such ester, tricresyl phosphate, has long been used as an anti-wear additive in lubricating oils.
