If the excitation of the shockabsorber 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.
The increased temperature influences greatly on reliability of seal and system when shockabsorber is working, the mechanism of heat generation when oil passes damping valve is analyzed.
针对减振装置工作时温升对密封件及系统可靠性影响较大的问题，分析了油液通过阻尼阀生热的机理。
