HYDRAULIC DAMPER Russian patent published in 2016 - IPC F16F7/09 F16F9/18 

FIELD: machine building.

SUBSTANCE: invention relates to machine building. Hydraulic damper comprises a cylinder, in which working fluid is tightly closed. Piston divides cylinder inner part into two chambers. Friction element is installed in the cylinder on the inner side of the sealing element and formed by an annular elastic rubber part. Part of the base comprises a lower section in the form of a disc with a drilled hole and a tubular section. Elastic rubber part comprises a section with minimum inner diameter and a section with increasing diameter on both sides in axial direction from the section with minimum inner diameter, formed on the inner circular side of the elastic rubber part. Elastic rubber part is made with a section of adjunction of the tubular section. Deepest part of the cut section is less deep than position in axial direction of the section with minimum inner diameter.

EFFECT: improved characteristics of damping force.
