HYDRAULIC DAMPER Russian patent published in 2015 - IPC F16F9/19 F16F6/00 

FIELD: machine building.

SUBSTANCE: hydraulic damper consists of a working cylinder coupled with a housing via rolling bodies. A piston is made from magnetic material. A magnetic ring rigidly fixed on the housing is in contact with the piston through an air gap. A splined pin made from resilient material is mounted inside the working cylinder. The splined pin is interconnected with mating splines of the piston. The piston is equipped with vertical throttle channels. The channels pass into L-shaped channels on the end face surfaces. The outlet holes of the channels adjoin plates with a gap. The plates are rigidly fixed on the piston.

EFFECT: change of damping characteristics.
