  • Fluid flow regulation of a vehicle shock absorber/damper
    Patent number: 7628259
    Abstract: Shock absorber components, such as a radial bypass damper, an anti-cavitation valve (ACV) and an incremental flow metering valve IFMV. The damper is of a continuous, unitary construction with a main hole and auxiliary holes interconnected by passageways. The ACV has openings that angle obliquely relative to entry surfaces of valving shims and extend at an incline continuously through the valving shims. The metering valve linearly regulates flow, substantially independent of piston displacement.
    Type: Grant
    Filed: November 8, 2004
    Date of Patent: December 8, 2009
    Assignee: Thyssenkrupp Bilstein of America, Inc.
    Inventors: Bret M. Norgaard, Douglas J. Cimins
