FIELD: labyrinth seals.
SUBSTANCE: proposed labyrinth seal laid between parts revolving axially relative to each other has at least two continuous circular sealing clearances located in succession in axial direction. End surface and sealing surface of circular sealing clearance are located in immediate proximity without contact, thus forming lateral working surfaces. At least one lateral surface of one circular sealing clearance is taper in shape; circular sealing clearances are inclined towards each other.
EFFECT: enhanced operational reliability of labyrinth seal.
