Compression sensitive suspension dampening

Abstract

A spring for a suspension is described. The spring includes: a spring chamber divided into at least a primary portion and a secondary portion, and a fluid flow path coupled with and between the primary portion and the secondary portion. The fluid flow path includes a bypass mechanism, wherein the bypass mechanism is configured for automatically providing resistance within the fluid flow path in response to a compressed condition of the suspension.

What we claim is: 
     
         1 . A component for a vehicle suspension, said component comprising:
 an upper leg tube;   a lower leg tube telescopically coupled to said upper leg tube;   a spring disposed in at least one of said upper leg tube and said lower leg tube and configured to provide a spring force which resists telescopic compression of said upper leg tube and said lower leg tube;   a first fluid chamber containing a first fluid, said first fluid chamber containing at least said spring, wherein said lower leg tube at least partially defines said first fluid chamber;   a second fluid chamber containing a second fluid, said second fluid chamber being disposed at least partially around said first fluid chamber; and   a dynamic seal positioned to separate said first fluid chamber from said second fluid chamber.
