<p>The structure has main piston valve assembly (30) which is installed at piston rod (20). The generated damping force is varied with respect to moving velocity of piston (55). A sub-piston portion (41) is secured at bottom portion of main piston valve assembly. A communication passage (42) is formed within piston rod so that interior (52) of housing (51) is connected to upper chamber (11). The piston is supported using upper and lower springs (47,58) such that piston is vertically moved within interior of housing. A slot (53) is formed in inner surface of housing.</p> |
