HYDRAULIC DAMPER WITH REINFORCED ROD SEAL Russian patent published in 2023 - IPC F16F9/36 

FIELD: mechanical engineering.

SUBSTANCE: hydraulic damper with a reinforced rod seal comprises a tank with a working cylinder placed in it. In the upper part of the working cylinder, there is a rod guide, in the central axial hole of which a rod equipped with a piston is movably fixed, as well as a rod gland holder with a tank nut and a casing cover in the upper part of the tank and the bottom of the tank with a valve compression, made with holes, at the bottom of the tank. The internal cavity of the working cylinder is divided by a piston into a rod part and a piston part. The rod has a reinforced seal in such a way that between the reservoir nut and the rod there is an upper wiper, fixed in the groove of the central axial through hole of the said nut, and between the rod guide and the rod there is a lower wiper fixed in the groove of the central axial through hole of the said guide.

EFFECT: expansion of operational capabilities is provided, consisting in the effective implementation of increased load-bearing capacity, stability, reliability and service life of the damper to increase the sealing of the device environment from the ingress of dust and dirt from outside in its upper part near the guide rod.
