HYDRAULIC DAMPER WITH RECOVERY DISPLACERS Russian patent published in 2023 - IPC F16F9/16 

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 tank is made in the form of a cylinder with a cylindrical recovery cavity formed in its internal part by means of the external part of the internal coaxially located working cylinder, where at least one recuperative displacer immersed in the working shock-absorbing fluid is freely located.

EFFECT: expansion of operational capabilities, flexibility of a wide range of settings for resistance forces, maximizing optimal damping at different speeds of piston movement, as well as reducing foaming of the working shock-absorbing fluid when the damper operates under conditions of differences in the operating temperature with the possibility of adjustment to the said conditions.
