摘要

FIELD: sealing engineering. ^ SUBSTANCE: seal comprises sealing and pressing rings made of materials of different flexibility and arranged parallel in the ring grooves. The material of the sealing ring has higher rigidity. The sealing ring is made of a V-shaped collar mounted with a spaced relation and rotation of its nibs no less than by 120° and cylindrical collar on the convex part which is in a contact with the pressing ring. The surface of the ring groove over the pressing ring is conical. The pressing ring may be round in cross-section and provided with a groove whose open part faces the pressure delivery. ^ EFFECT: enhanced reliability of sealing. ^ 3 cl, 6 dwg
