FIELD: engines and pumps.
SUBSTANCE: invention relates to aircraft engineering, particularly, to oil chamber seal. The latter is composed of at least one spinning member and one stationary member of turbojet engine to retain the suspension of lubing oil drops (h). It includes at least one brush seal with tightly packed row of fibres. This ensures tightness between at least one spinning member and one stationary member of turbojet engine. This device includes the means for oil suspension portion recovery in inner volume (V). Besides, it comprises the means for delivery of said collected oil (h) and oil cycling along said brush seal fibres directed in spinning member direction. Claimed seal resists the coking.
EFFECT: higher efficiency and stability of seal.
