HYDRAULIC SHOCK ABSORBER Russian patent published in 2013 - IPC F16F9/19 

FIELD: machine building.

SUBSTANCE: hydraulic shock absorber comprises a reservoir with an operating cylinder filled with a working fluid. Inside the cylinder there is a piston installed movably with valves. The piston is rigidly fixed on the stem interconnected with the protective jacket. The working cylinder and the protective jacket are made of diamagnetic material. The protective jacket contacts with its inner circular surface with the responsive surface of the working cylinder via a row of revolution solids. In the space between rows of solids of revolutions inside the specified protective jacket there is a ring rigidly fixed, made of a permanent magnet. The ring interacts with its magnetic field via an air gap and a wall of a working cylinder with a cylindrical circular generatrix surface of a magnetoconductive piston of a shock absorber.

EFFECT: increased reliability and simplified design of hydraulic shock absorbers.
