    • Disclosed is a door damper, in which a safety check valve is installed in consideration of the case in which an impact exceeding a design pressure will be applied, thereby absorbing the impact to enable a door to be closed safely and smoothly. In the door damper, a safety check valve is installed in a piston, and thus is opened in cooperation with another check valve installed between a spring holder and the piston when the pressure exceeding a design pressure is applied. Thereby, when the impact exceeding the design pressure occurs, the safety check valve can absorb the impact to prevent damage. A channel can be adjusted by only ridges formed on an outer circumference of the check valve, so that productivity can be improved thanks to easy tolerance management. Further, an oil seal is not contracted or deformed in spite of long-term use.
    • 公开了一种门阻尼器,其中考虑到将施加超过设计压力的冲击的情况来安装安全止回阀,从而吸收冲击以使门能够安全平稳地关闭。 在门阻尼器中,安全止回阀安装在活塞中,因此当施加超过设计压力的压力时,与安装在弹簧保持器和活塞之间的另一止回阀协同打开。 因此,当超过设计压力的冲击发生时,安全止回阀可以吸收冲击以防止损坏。 可以通过形成在止回阀的外周上的脊部来调节通道,从而通过容易的公差管理可以提高生产率。 此外,油封尽管长期使用也不会收缩或变形。
