Abstract
A gas spring includes a piston assembly or pack having an additional seal, pressure relief valve, and check valve that increases the output force of the gas spring. Various temperature compensation structures, also added to the piston pack, permits this increase to vary from zero at higher ambient temperatures to a maximum value at very cold temperatures thus achieving a temperature compensation, which varies, in an analog manner, inversely in response to the temperature changes.
