Method of changing damping characteristics of twin-tube shock absorber
Abstract:
The present invention provides a method of optionally changing damping characteristics of a twin-tube shock absorber.In the method of changing the damping characteristics of the twin-tube shock absorber (10), a threaded hole (11a) is formed in an outer tube (11), oil is drained from the inside of the twin-tube shock absorber (10) through the threaded hole (11a), replacement oil (35) is charged into the twin-tube shock absorber (10), and a check valve (20) is mounted in the threaded hole (11a). Thereafter, in a state that the check valve (20) is positioned on the upper side in the twin-tube shock absorber (10), a gas is sucked out from the inside of the twin-tube shock absorber (10) through a flow channel of the temporarily opened check valve (20), and a replacement nitrogen gas (36) is injected into the twin-tube shock absorber (10).
Abstract(Chinese):

本发明提供一种可选地改变双管减震器的阻尼特性的方法。 在改变双管减震器（10）的阻尼特性的方法中，在外管（11）中形成螺纹孔（11a），从双管减震器（10）的内部排出油 ）通过螺纹孔（11a），替换油（35）被装入双管减震器（10）中，止回阀（20）安装在螺纹孔（11a）中。 此后，在单向阀减震器（10）的上侧设有止回阀（20）的状态下，通过流动从双管减震器（10）的内部吸出气体 临时打开的止回阀（20）的通道和替换氮气（36）被注入到双管减震器（10）中。
