HYDRAULIC DAMPER Russian patent published in 2023 - IPC F16F9/14 

FIELD: mechanical engineering.

SUBSTANCE: hydraulic damper 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 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 piston comprises built-in independent valves, each of which is located in the cylindrical body of the piston and is made in the form of a screw or bolt, on which a spring steel washer, a spring, a piston washer and a nut are installed.

EFFECT: expansion of operational possibilities, flexibility of a wide range of resistance force settings, maximizing optimal damping at various piston speeds.
