But some hydraulic oil is not common, is the high point of the special dampingoil, hydraulic oil with the principle of similar.
但有的不是普通的液压油，高级一点的是专用的减震油，工作原理同液压油类似。

The controllable dampers are designed according to two basic principles which change damping force by changing the flow area of valves in damper and changing flow behaviors of dampingoil.
主动阻尼器一般根据两种原理进行设计——改变阻尼器阻尼通道的流通面积和改变阻尼器中阻尼液的流动特性。

If the excitation of the shock absorber is greater, the control piston moves to its limit position so that oil ceases flowing through the bypass duct, meaning that the full damping force is available.
