US Patent:

6464048, Oct 15, 2002

Filed:

Jul 24, 2000

Appl. No.:

09/624682

Inventors:

Gary W. Groves - Monroe MI
Karl Kazmirski - Toledo CO
David L. Steed - Perrysburg OH
Michael L. Zebolsky - Tecumseh MI

Assignee:

Tenneco Automotive Inc. - Lake Forest IL

International Classification:

F16F 934

US Classification:

1882666, 188315

Abstract:

A shock absorber includes a pressure tube with a piston slidably disposed therein. A separate valve includes a fluid circuit for fluid low in rebound and a fluid circuit for fluid flow in compression. Each fluid circuit includes a variable orifice which allows selection between a firm rebound with a soft compression, a soft rebound with a soft compression and a soft rebound with a firm compression. Each variable orifice is in communication with a blowoff valve in such a manner that they provide a variable blowoff feature to the blowoff valves.

Assignee:

The Pullman Company - Milan OH

International Classification:

F16F 904

US Classification:

267 6424

Abstract:

An upper mounting system for a MacPherson strut includes a shock absorber mount and an air spring mount. The air spring mount is disposed coaxially around the shock absorber mount. A curved spherical interface of the air spring mount permits pivotal movement of the air spring such that it maintains a coaxial relationship with the shock absorber. The curved spherical interface also provides a seal for sealing the gas chamber of the air spring.

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.
