Patent ID: 7311182

Claim:
A sealing and guiding packet for shock dampers, comprising: a ring encompassing a piston rod driven to oscillate, said ring being in contact with said piston rod; said ring having a first end face and a second end face; said ring having also a cylindrical mantle surface; a cylindrical elastomer element surrounding said ring and having two radially projecting flanges thrusting said ring resiliently against said end faces; said elastomer element having a radially extending flange biasing said ring against said piston rod; biasing elements on said elastomer element and holding said elastomer element under bias in both axial and radial directions when in a working state; pressure passages for applying pressure to said elastomer element and carrying fluid under pressure when in the working state, said fluid acting directly or indirectly on said elastomer element and producing pressure relief of said elastomer element against internal pressure of a shock damper.
