CABLE BUMPER Russian patent published in 2011 - IPC F16F7/14 F16F13/00 

FIELD: machine building.

SUBSTANCE: bumper consists of flexible element made of sections of steel cable of arc-shape. Sections are arranged in a row to the left and right along length of upper and lower bearing plates and are secured in them by means of straps. Vertices of arcs of sections face vertical axis of the bumper. Hydraulic dampers are fixed in the bearing plates along total length of the straps. Each damper is formed with two coaxial cylinder sleeves. A pressure tight circular cavity is formed between the external and internal sleeves. An upper part of the cavity is closed with a movable circular flange with packings along internal and external surfaces, while a lower one is closed with a circular washer. A circular piston with throttling orifices is arranged in the circular cavity. The piston is pivotally connected with the circular flange by means of at least three control rods; a spring rests on the circular flange. An upper base of the spring rests against a cover rigidly tied with a rod of the damper. The bush is rigidly connected with a cover and functions as a guiding device for the spring. The rod is installed coaxially to the sleeves. A lower end of the rod is connected with the vibration isolated object, while the upper one - with the cover.

EFFECT: raised efficiency of vibration insulation under resonance mode.
