MECHANICAL SEAL OF ROD Russian patent published in 2025 - IPC F16J15/56 

FIELD: sealings.

SUBSTANCE: invention relates to sealing equipment, in particular to mechanical seals intended for installation on hydraulic pneumatic machines and devices, which working members make reciprocating movement, and can be used in oil and gas industry, as well as in various branches of machine building. Mechanical rod sealing containing sealing rings ground to each other at the ends and pressed to the sealed surface by the elastic cage, characterized in that the sealing rings are made with radial cuts, wherein radial cuts of adjacent sealing rings are diametrically opposite. O-rings cross-sections have a T-shape, the O-rings face the sealing surface with a wide part, and in cavities between circular ribs of adjacent sealing rings elastomeric rings are arranged to height level of circular ribs, wherein the set of sealing and elastomer rings is enclosed by an elastic elastomer cage, the ends of which are embedded between the end mandrels and the perforated housing surrounding the elastic elastomer cage.

EFFECT: invention is distinguished by its greater technological advancement, relative simplicity, and reliability.
