FIELD: mechanical engineering; gas-turbine engines of aircraft and ground applications. SUBSTANCE: according to invention, in compressor of gas- turbine engine with radial-thrust antifriction bearing, sealing of oil space in form of labyrinth seal with oil-deflecting lip is made double-tier, with ratio of outer diameter of oil-deflecting lip and mean diameter of bearing being 1.01-1.2, and ratio of value of axial clearance between stator flange of labyrinth upper tier and oil-deflecting lip to value of axial clearance between stator flange of lower tier and plate of outer labyrinth being 1.01-1.5. Invention is aimed at prevention of getting of seal wear products into bearing and damaging of oil-deflecting lip in process of compressor demounting. EFFECT: improved reliability of compressor of gas-turbine engine. 3 dwg
