FIELD: chemical engineering. SUBSTANCE: apparatus consists of cylindrical cavity containing tangential oil-supply channel operated under pressure, tangential purified oil-discharge channels, and axial channel for releasing air removed from deaerated oil. Oil-supply channel is located in lower part of cylindrical cavity, whereas tangential oil- discharge channels and axial air-release channel are disposed in its upper part. Apparatus functions in vortex mode. EFFECT: ensured possibility to remove air bubbles from aircraft-engine lubricating oils in any configurations and conditions of flight. 3 cl, 3 dwg
