摘要： Provided is a piston valve of a shock absorber which can achieve both an effect of varying an attenuation force according to a pressure and an effect of varying an attenuation force according to a frequency region. The piston valve includes: a main valve unit coupled to a lower end of a piston rod formed with an orifice hole, to divide an inside of a cylinder into an extension chamber and a compression chamber, the main valve unit generating an attenuation force according to a difference of pressure between the extension chamber and the compression chamber; and a frequency sensitive valve unit installed at one side of the main valve unit and configured to generate an attenuation force according to a frequency of hydraulic fluid delivered through the orifice hole of the piston rod, wherein the frequency sensitive valve unit is installed within the main valve unit.

摘要： Provided is a shock absorber, which has a cylinder filled with a fluid, a piston valve dividing the cylinder into a rebound chamber and a compression chamber, and a piston rod extending to the outside of the cylinder in a state of being connected to the piston valve. The shock absorber includes: a free piston which divides the compression chamber into an upper chamber and a lower chamber in such a state that the piston rod vertically passes through the free piston, and forms a vertical passage such that the upper chamber and the lower chamber are connected to each other; and a support which is connected to the piston rod, with a larger diameter, increases a pressure of the upper chamber by locally tightly contacting and ascending the free piston from below during a rebound stroke of the piston rod, and forms a horizontal passage connected to the vertical passage.

摘要： Disclosed herein is a combining structure of a shock absorber including a stopper assembly adapted to surround opposite ends of a bypass passage formed in a piston rod of the shock absorber, with at least one gateway provided to promote smooth flow of a working fluid, and to keep a piston valve firmly pressed against the piston rod and fixed. The combining structure may ensure that the overall length of the shock absorber does not unnecessarily increase, while generating normal damping force without interference with flow of the working fluid.
摘要翻译：本文公开了一种减振器的组合结构，该减震器包括适于围绕形成在减震器的活塞杆中的旁通通道的相对端部的止动器组件，至少一个通道用于促进工作流体的平稳流动，并且将活塞阀牢固地压靠活塞杆固定。组合结构可以确保减震器的总长度不会不必要地增加，同时产生正常的阻尼力而不干扰工作流体的流动。
