ABSTRACT:
A temperature compensated gas spring mechanism comprises a main gas spring energized by a pressure source that generates primary forces in excess of the selected design forces for the mechanism and a secondary gas spring energized by a second pressure source that generates forces opposed to those of the main gas spring and of magnitudes approximately equal to the excesses of the primary forces over the selected design forces, thereby a compensate to a substantial extent for changes in the primary pressure due to temperature variations.
