Patent abstract
A gas spring for a vehicle suspension system includes a cylinder, a rod disposed within the cylinder, a relative movement between the rod and the cylinder changing the volume of a chamber formed between the rod and the cylinder, and an accumulator in communication with the chamber. Compression of gas in the chamber at least partially provides a first spring rate for deflections of the gas spring below a threshold, compression of gas in the chamber at least partially provides a second spring rate for deflections of the gas spring above the threshold, and the first spring rate is greater than the second spring rate.
