FIELD: machine building.
SUBSTANCE: radial-end contact seal of a turbomachine support comprises two elastic graphite rings with cross cuts installed at the turbomachine rotor, contact rings with their end surfaces contacting the end surfaces of the said elastic graphite rings, and a bush. The seal comprises the third elastic graphite ring with a cross cut placed between the said elastic graphite rings and installed at the turbomachine rotor with the outer rotor surface contacting the inner bush surface; the contacting surfaces of the third elastic graphite ring and the said contact rings are tapered.
EFFECT: increased service life of a graphite seal due to slipping in the area of contact of graphite rings in respect to the contact rings and the bush.
