緩衝器
Document Type and Number:
Japanese Patent JP4050514
Kind Code:
B2
Abstract:
The invention relates to a shock absorber having high dissipating power and comprising a rod-and-piston assembly (12) slidably received in a cylinder (11) and defining on either side of the piston (13) respective working chambers (18; 19) containing hydraulic fluid. In the invention, each working chamber (18, 19) communicates continuously with an associated chamber (20, 21) containing a heterogeneous energy absorption-dissipation structure constituted by a capillo-porous matrix (51, 61) and an associated liquid (52, 62) relative to which the matrix is lyophobic. In addition, each working chamber (18, 19) communicates with a common compensation chamber (30) via an associated valve system (32, 33) including non-return means (40, 41) ensuring that the working chamber concerned closes automatically during compression, and opens during expansion.
