HYDRAULIC MECHANICAL DAMPER Russian patent published in 2012 - IPC F16F9/14 F16F5/00 

FIELD: machine building.

SUBSTANCE: damper includes working cylinder with elastic stock and piston arranged in it. Radial ribs and projections having the channels bent at right angle to longitudinal stock axis are provided on piston edge. Discs of smaller diameter in comparison to diameter of piston are adjacent to above-piston and under-piston end surfaces of piston with possibility of angular rotations. Discs are rigidly fixed on stock of solid cross-section, which is arranged in hollow stock in movable manner. Channels of curved shape, which interact with channels of stocks of solid and hollow cross sections, are made in discs. Channels include ball-shaped movable body designed for overlapping of curved shape of disc channels. Spiral-shaped through slots which have variable cross section throughout their length are made in discs coaxially to vertical channels of piston.

EFFECT: higher efficiency of damping characteristics.
