US Patent:

7216747, May 15, 2007

Filed:

Oct 12, 2005

Appl. No.:

11/248102

Inventors:

Darrell Breese - Ypsilanti MI, US

Assignee:

Tenneco Automotive Operating Company Inc. - Lake Forest IL

International Classification:

F16F 9/10
F16F 9/34

US Classification:

188315, 188318, 18832213

Abstract:

A dual tube shock absorber includes a spool valve located between the upper working chamber and the reserve chamber. The spool valve moves with the piston rod to open and close a flow path between the upper working chamber and the reserve chamber. This provides a low damping characteristic for small movements of the piston rod which changes to a high damping characteristic for larger movement of the piston rod.

US Classification:

188280, 18832215, 18832222, 188315, 188275, 1882828

Abstract:

A shock absorber has a compression valve assembly which functions during a compression stroke, a rebound valve assembly which functions during a rebound stroke and a velocity sensitive valve which is in series with one or both of the compression valve assembly and the rebound valve assembly. The compression valve assembly, the rebound valve assembly and the velocity sensitive valve can be incorporated into a piston assembly, a base valve assembly or both.

International Classification:

F16F 9/50

US Classification:

1882824, 18832214, 18832213, 1882665, 188315

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.

Assignee:

Tenneco Automotive Operating Company, Inc. - Lake Forest IL

International Classification:

F16F 9/508

US Classification:

188280

Abstract:

A shock absorber includes a pressure sensitive valve assembly that controls fluid flow through the pressure sensitive valve assembly based upon the velocity of the piston assembly in the shock absorber. The pressure sensitive valve assembly restricts fluid flow as the velocity of the piston in a compression stroke increases to increase the damping loads provided by the shock absorber.
