VIBRATION ISOLATOR Russian patent published in 2013 - IPC F16F9/18 F16F9/48 F16F15/27 

FIELD: machine building.

SUBSTANCE: vibration isolator contains the first and the second base, bearing flexible element and hydraulic damper attached between bases and two retainers. Hydraulic damper is made in a form of cylinder with piston and rod. At the bottom front part of the cylinder there is a subsidiary cavity and installed valve and throttling element. The valve is designed for fluid passing from subsidiary cavity to under-piston cavity of the cylinder. Subsidiary cavity is connected to above-piston cavity of the cylinder by hydraulic channel. Throttling element is designed for fluid passing from under-piston cavity into subsidiary cavity with obtaining stepped characteristic of dissipative force. The first retainer is attached to the first base and pin-connected to the rod. The second retainer is fixed on the second base and pin-connected to the cylinder. These two connections provide horizontal location of hydraulic damper.

EFFECT: increase of vibration isolation efficiency of objects via obtaining optimal stepped-falling characteristic of compensating influence.
