  • Air pressure proportional damper for shock absorber
    Patent number: 7562750
    Abstract: An air pressure proportional damper includes a first chamber and a second chamber. The first chamber is fluidly attached to the second chamber through an air adjustment valve. The air adjustment valve regulates flow from the first chamber to the second chamber in proportion to air pressure received from an accompanying air spring.
    Type: Grant
    Filed: February 10, 2004
    Date of Patent: July 21, 2009
    Assignee: Tenneco Automotive Operating Company Inc.

  • Stroke dependent damping
    Patent number: 7320388
    Abstract: A two-stage shock absorber has a pressure tube within which a valve assembly is slidably disposed. A piston rod is attached to the valve assembly and extends out of the pressure tube. A ring is slidably disposed within the pressure tube and engages the valve assembly. After a specified amount of movement of the valve assembly with respect to the pressure tube in an extension movement of the shock absorber, the sleeve engages a plurality of spirally positioned bores and reduces the fluid flow through the valve assembly to progressively switch the shock absorber from soft damping to firm damping. In another embodiment the sleeve engages a spiral groove of variable depth to reduce the fluid flow through the valve assembly to progressively switch the shock absorber from soft damping to firm damping.
