Abstract: Methods and apparatus for accommodating vehicle suspensions that may bottom out. Some embodiments of the present invention include the secondary shock absorber placed within a primary shock absorber. Yet clear embodiments describe a shock absorber having multiple fluid flowpaths during compression, with one of the flowpaths being active near the bottoming-out condition.

Abstract: A bi-linear platform reactive damper for automotive type vehicles, which includes a damper housing having a chamber with a damper piston in it, which piston has a rod extending from it connected to the suspension of the vehicle, which chamber is filled with hydraulic fluid, the chamber being connected to an external reservoir containing a separator piston, with gas on the side of the piston opposite to the hydraulic fluid, and having an adjustable separator piston stop.
