PRESSURE FLUID, METHOD OF PRODUCTION OF PRESSURE FLUID AND PRESSURE FLUID FOR HIGH- PRESSURE UNITS USED FOR TRANSFER OF ENERGY UNDER LOAD Russian patent published in 2002 - IPC

FIELD: hydraulic systems. SUBSTANCE: pressure fluid is based on esters of tall oil and polyethylene glycol or polyhydroxyl compounds of neopentane, such as trimenthyl propane, pentaerythritol, trimethyl ethane, trimethyl butane, neopentyl glycol; it also contains at least oxidizing inhibitor, corrosion inhibitor, foam suppressor and high-pressure lubricant. Pressure fluid is obtained through esterification of tail oil and polyhydroxyl compounds. EFFECT: enhanced efficiency. 8 cl, 1 dwg, 3 tbl
