Title:
DAMPER WITH DIGITAL VALVE
Document Type and Number:
WIPO Patent Application WO/2011/043928
Kind Code:
A3
Abstract:
A shock absorber has a compression valve assembly that provides a high damping load during a compression stroke and an extension valve assembly that provides a high damping load during an extension stroke. One or more digital valve assemblies is positioned to work in parallel with the compression valve assembly and the extension valve assembly to provide a lower damping load. The lowering of the damping load is based upon the cross sectional area of flow passages provided by the one or more digital valve assemblies.
