Abstract

A piston cylinder gas spring uses a combination of fluids to achieve a spring force which is more nearly constant with change in temperature than it would be if a single fluid were used. A primary pressure source is located within the casing (in chambers 26, 34) and acts against the piston 24 to urge the rod 30 out of the casing. A secondary pressure source is located within the casing (in chambers 28, 36) and acts against the piston to urge the rod into the casing. The primary pressure created by the primary pressure source is greater than the secondary pressure created by the secondary pressure source, and the percent change of the secondary pressure with temperature variation is greater than the percent change of the primary pressure with the same temperature variation. The primary source is nitrogen. The secondary source is a two phase liquid/vapour system e.g. acetylene, freon, ammonia, hydrogen bromide, sulphur hexafluoride.
