VIBRATION INSULATING SYSTEM BY KOCHETOV Russian patent published in 2010 - IPC F16F9/16 

FIELD: machine building.

SUBSTANCE: vibration insulating system consists of four dampers with pendulum suspension, which are connected with support elements of equipment. The damper consists of compression spring interacting with base of case and the pendulum suspension. The damper also consists of the base, of the guiding device and of a shock-absorbing device pivotally joined with the base by means of a bracket with a base. The damper is formed with two coaxial cylinder sleeves. A pressure tight circular cavity is formed between external and internal sleeves. An upper part of the cavity is closed with a movable circular flange with packing along internal and external surfaces, while a lower one is closed with a circular washer. A circular piston with throttling holes is arranged in the circular cavity. The piston is hinged by means of at least three rods with the circular flange whereupon a spring rests. An upper base of the spring thrusts against a cover rigidly connected with a rod of the damper. A bushing is rigidly tied with the cover and operates as a guide for the spring. The rod is installed coaxially to sleeves. A lower end of the rod is connected with a vibration protected object, while an upper one is connected with the cover.

EFFECT: increased efficiency of anti-vibration in resonance mode and simplification of design and assembly of damper.
