FIELD: seal.
SUBSTANCE: invention relates to a radial sealing device with a bypass of the working medium in which a U-shaped profile with an inclined wall is applied which rests on the inner-widening surface of the first flange, and the inclined wall rests on the outer surface of the inlet part of the second flange. In this case, the bypass of the working medium is carried out through the holes in the top of the U-shaped profile of the sealing ring, and the sealing device has the elements for fixing the sealing ring, for example, the second flange has, on the outer surface of the inlet portion, projections securing the sealing ring.
EFFECT: invention increases the reliability of operation and provides an even radial clearance between the sealing flanges.
