Abstract: A shock absorber includes a piston assembly which includes separate flow paths. Each flow path is controlled by a valve assembly and each flow path is in parallel with the other two flow paths. One flow path will generate firm damping characteristics. A second flow path opens depending on either the frequency of the shock absorber movement or the amount of movement or stroke of the shock absorber. The third flow path includes an on/off control valve and generates a soft damping characteristic when the control valve is activated. The soft damping characteristic can be generated by a tunable bleed restriction or by a passive valve assembly.
Abstract translation: 减震器包括一个活塞组件，它包括单独的流路。 每个流动路径由阀组件控制，并且每个流动路径与另外两个流动路径平行。 一个流路将产生稳定的阻尼特性。 第二流路根据减震器运动的频率或减震器的运动或行程量而打开。 第三流路包括开/关控制阀，并且当控制阀被启动时产生软阻尼特性。 软阻尼特性可以通过可调节的泄放限制或被动阀组件产生。

Abstract: A shock absorber has a pressure tube with a piston assembly slidably disposed within the pressure tube and attached to a piston rod. The piston assembly divides the pressure tube into an upper working chamber and a lower working chamber. The piston assembly includes a frequency dependent valve assembly attached to the piston rod which defines a housing attached to the piston rod and a spool valve assembly. The spool valve assembly includes a spool valve and a bypass valve assembly that controls fluid flow through bypass passage that bypasses the piston assembly.

Abstract: A shock absorber has a pressure tube with a piston assembly slidably disposed within the pressure tube and attached to a piston rod. The pressure tube is disposed within a reserve tube and a working fluid reservoir is formed between the pressure tube and the reserve tube. The piston assembly divides the pressure tube into an upper working chamber and a lower working chamber. A base valve assembly controls a flow of working fluid between the working fluid reservoir and the lower working chamber. The base valve assembly includes a frequency dependent valve system that provides an increased level of damping for each compression stroke of the piston assembly during low frequency movements of the shock absorber. A lesser level of damping is provided for each compression stroke during high frequency movements of the shock absorber.
