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

FIELD: engineering industry.

SUBSTANCE: damper consists of the working cylinder in which the two-piece piston is movably placed. Piston parts are rigidly fixed on hollow and continuous rods of round section and supplied on the surfaces by radial edges and protuberances with bent under a right angle to a horizontal and vertical plane of the piston channels. Surfaces of the radial edges converted to horizontal sites of channels, are executed in the curvilinear shape. Symmetry direct-axes are located in the lower part of curvilinear surfaces of radial edges in a place of their adjunction to piston parts. Face surfaces of protuberances have the curvature that is adequate to curvilinear surfaces of edges.

EFFECT: increasing of a torque; deriving of better performances of the oscillations damping.
