| 摘要 |
<p>The invention concerns a damper with high dissipating power comprising a piston-rod assembly (12) sliding in a cylinder (1) defining on either side of the piston (13) a working chamber (18, 19) containing hydraulic fluid. The invention is characterised in that each working chamber (18, 19) communicates permanently with an associated chamber (20, 21) containing a heterogeneous energy absorbing-dissipating structure consisting of a porous capillary matrix (51, 61) and an associated liquid (52, 62) towards which the matrix is lyophobic. Further, each working chamber (18, 19) communicates with a common equalizing chamber (30) via an associated valve system (32, 33) including non-return means (40, 41) which automatically closes the chamber concerned during compression, and opens said chamber during expansion.</p> |
