其作用是控制油路中油压的大小。

Its role is to control the hydraulic oil circuit in size.

如果减振器的振幅变大，控制活塞会移动到它的极限位置然后会终止旁通孔的油路，从而开始提供完全的阻尼力。

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.
