HYDRAULIC DAMPER Russian patent published in 2014 - IPC F16F9/14 F16F5/00 

FIELD: machine building.

SUBSTANCE: invention relates to machine building. A hydraulic damper includes an operating cylinder, in which an arrangement is made for an elastic stock with a piston rigidly fixed on it and on its end face there are radial ribs and projections having passes bent at a right angle to the piston axis. On a vertical generatrix of the cylindrical surface of the piston there are slots of a similar shape. The slots are connected on one side to the passes arranged in walls of the operating cylinder throughout their height and connected both to its below-piston and above-piston cavities, and on the other side, they are connected to the passes located in the piston. Opposite ends of channels have an L-shape and are located with a gap relative to the ribs rigidly fixed on upper and lower end surfaces of the piston.

EFFECT: achieving enlargement of operating characteristics of hydraulic dampers.
