FIELD: engines and pumps.
SUBSTANCE: invention relates to aircraft engineering, namely to oil cavity seals in gas turbine engines and power plants. Radial-end seal is equipped with two graphite rings installed on the shaft on both sides of circular elements adjacent to each other, two contact bushings installed on the shaft on both sides of graphite rings, the protruding areas to form a ring arranged with clearance relative to external surfaces of graphite rings with possibility of contact of its outer surface with inner surface of cylindrical section outer shaft and stator Note here that contact sleeve, graphite ring and ring elements are fixed on the shaft in axial direction, and between one of contact sleeves and nearby graphite ring is installed axial spring.
EFFECT: increased service life and wider application field of gas turbine engines and power plants.
