Abstract
A gas spring for a vehicle suspension system includes a cylinder, a rod disposed within the cylinder, the rod and the cylinder defining a chamber, and an accumulator in communication with the chamber. The rod and the cylinder are configured such that a relative movement therebetween changes the volume of the chamber. Gas in the chamber and the accumulator are configured to cooperate to at least partially provide a spring rate that varies based on at least one of a deflection and a spring force associated with at least one of the rod and the cylinder.
