FIELD: aviation.
SUBSTANCE: invention relates to aircraft engine building, namely to seals of oil cavities of supports of gas turbine engine rotors. Task of expanding the range of equipment - reliable interval contact seals of coaxial high-speed rotors with opposite direction of rotation and increase in their reliability is solved by interval contact sealing of oil cavity of support of coaxial high-speed rotors of opposite direction of rotation of turbomachine, containing graphite sealing rings 8, contacting with end contact surfaces of shafts 9, 10, wherein in shaft 5 of one of rotors cage 7 is installed with possibility of its rotation relative to common axis of rotation of rotors 14, and graphite sealing rings 8, with elastic element between them 11, are installed in the cartridge in a fixed angular position.
EFFECT: wider range of equipment.
