两级阀和液压阻尼阀
摘要：
一种减震器，包括具有两个阀盘的两级阀组件。第二阀盘限定在较低阀压下的第一级，第一阀盘限定在较高阀压下的第二级。所述两个阀盘可由整体部件限定，或者它们可为分离的部件。所述第二阀盘可通过所述第二阀盘的偏转或整个第二阀盘的运动允许流体流动。所述两级阀组件可被包含到所述减震器的活塞组件中和/或所述两级阀组件可被包含到底阀组件中。
摘要（英）：

A shock absorber includes a two stage valve assembly that has two valve discs. The second valve disc defines the first stage at lower valve pressures and the first valve disc defines the second stage at higher valve pressures. The two valve discs can be defined by a single piece component or they can be separate components. The second valve disc can permit fluid flow by deflection of the second valve disc or by movement of the entire second valve disc. The two stage valve assembly can be incorporated into the piston assembly of the shock absorber and/or the two stage valve assembly can be incorporated into a base valve assembly.
