HYDRAULIC DAMPER Russian patent published in 2008 - IPC F16F9/14 F16F5/00 

FIELD: engineering industry.

SUBSTANCE: hydraulic damper consists of working cylinder in which two-piece piston is movably placed. Piston parts are rigidly fixed on hollow and continuous rods of ring and continuous round section, and supplied by channels for hydraulic fluid transiting. In the lower part of a continuous rod the channel is executed. This channel is linked, at least with two open coaxial holes located in its diametrical plane. Walls of a hollow rod lay in a horizontal plane of these holes, and are supplied with open slots varying on height of rods. Each of slots is directed on an external and internal generatrix of a hollow rod to each other by the ends having their least height.

EFFECT: operational efficiency upgrading of a damper due to improvement of its damping performances.
