Embodiment Construction

[0025] The following description is merely exemplary in nature and is not intended to limit the disclosure, application or uses. figure 1 A vehicle is shown in , which incorporates a suspension system having a shock absorber according to the teachings of the present invention and is generally designated by the reference numeral 10 . Vehicle 10 has been depicted as a passenger car having front and rear axle assemblies. However, shock absorbers according to the present teachings may be used with other types of vehicles or for other types of applications. Examples of these alternative arrangements include, but are not limited to, vehicles incorporating non-independent front and / or non-independent rear suspensions, incorporating independent front and / or independent rear suspensions, or other suspensions known in the art system vehicles. Furthermore, the term "shock absorber" as used herein is intended to mean a damper in general and will thus include McPherson struts and other d...

Abstract

A shock absorber has a housing with a piston rod assembly disposed therein. A first rod guide member is secured within a first portion of the housing so as to be concentrically disposed about at least a portion of the piston rod assembly. A second rod guide member is secured within the housing adjacent the first rod guide member so as to be concentrically disposed about at least another portion of the piston rod assembly. A digital valve assembly is disposed within the second rod guide member and fluidly couples chambers within the shock absorber.
