摘要： A two-stage shock absorber has a pressure tube within which a valve assembly is slidably disposed. A piston rod is attached to the valve assembly and extends out of the pressure tube. A ring is slidably disposed within the pressure tube and engages the valve assembly. After a specified amount of movement of the valve assembly with respect to the pressure tube in an extension movement of the shock absorber, the sleeve engages a plurality of spirally positioned bores and reduces the fluid flow through the valve assembly to progressively switch the shock absorber from soft damping to firm damping. In another embodiment the sleeve engages a spiral groove of variable depth to reduce the fluid flow through the valve assembly to progressively switch the shock absorber from soft damping to firm damping.
摘要翻译：两级减震器具有压力管，阀组件可滑动地设置在该压力管内。活塞杆连接到阀组件并延伸出压力管。环可滑动地设置在压力管内并接合阀组件。在减震器的延伸运动中阀组件相对于压力管的指定量的移动之后，套筒接合多个螺旋定位的孔并且减少流过阀组件的流体流动，以逐渐地将减振器从软阻尼到坚固的阻尼。在另一个实施例中，套筒接合可变深度的螺旋槽，以减少通过阀组件的流体流动，以逐渐地将减振器从软阻尼切换到牢固的阻尼。
