一种阻尼卸载阀以及粘滞阻尼器
摘要：
本申请公开一种阻尼卸载阀以及粘滞阻尼器。阻尼卸载阀，应用于粘滞阻尼器的活塞中，其包括阀体、阻尼阀芯以及泄压阀芯，阀体内形成有贯穿阀体的阻尼油道和泄压油道，阻尼阀芯设于阻尼油道，泄压阀芯设于泄压油道。当粘滞阻尼器内的油压超过第一预定压力时，阻尼阀芯封闭阻尼油道。当粘滞阻尼器内的油压超过第二预定压力时，泄压阀芯打开泄压油道。阻尼卸载阀以及粘滞阻尼器能够解决现有的粘滞阻尼器遇到过大载荷时，粘滞阻尼器受损，阻尼失效的问题。
摘要（英）：

The invention discloses a damping unloading valve and a viscous damper. The damping unloading valve is applied to a piston of the viscous damper, and comprises a valve body, a damping valve element and a pressure relief valve element, a damping oil way and a pressure relief oil way penetrating through the valve body are formed in the valve body, the damping valve element is arranged in the dampingoil way, the pressure relief valve element is arranged in the pressure relief oil way, when the oil pressure in the viscous damper exceeds the first reserved pressure, the damping valve element blocks the damping oil way, and when the oil pressure in the viscous damper exceeds the second reserved pressure, the pressure relief valve element opens the pressure relief oil way. The damping unloadingvalve and the viscous damper can solve the problems that when an existing viscous damper has the too large load, the viscous damper is damaged, and damping fails can be solved.
