Abstract
Methods and apparatus for position sensitive dampening with an active valve.

Claims8
A damper for a shock absorber comprising:
- a damper chamber divided by a piston and shaft into a compression portion and a rebound portion;
- a bottom out control feature at an end of the compression portion, said bottom out control feature comprising:
- a component connected at an end of said shaft, said component separate from said piston, said component configured such that near a limit of a compression stroke, said component causes increased dampening of said damper;
- a fluid flow path formed in the bottom out control feature for providing fluid communication from the bottom out control feature to the compression portion of the damper chamber during a compression stroke of the damper;
- and
- an active valve coupled with said fluid flow path, said active valve to meter a fluid flow of a working fluid through said fluid flow path.
