Abstract
A vehicle suspension system includes a pump, a gas spring, and an accumulator. The gas spring assembly includes a cylinder, a rod, and a chamber for supporting gas. The rod is coupled to the cylinder and moveable relative to the cylinder. The chamber is formed between the cylinder and the rod, where movement of the rod relative to the cylinder changes the volume of the chamber. The accumulator is configured for receiving, storing, and releasing potential energy from gas of the chamber. The accumulator is coupled to the chamber, and is in gaseous communication with the chamber such that a continuous body of gas extends between the chamber and the accumulator when the accumulator is receiving or releasing the potential energy.
