<p>A damper device (10) has a sealed damper chamber (70) defined by a flexible diaphragm (20) and an upper cap (40). The damper chamber is filled with a pressurizing agent that creates a pressurized condition in the damper chamber by a phase transformation to the gaseous state from a solid or liquid state. To form the pressurized damper, the pressurizing agent is placed in the upper cap of the damper chamber in a solid or liquid state. The diaphragm is then positioned across the opening of the upper case and sealed in position, as for example by crimping the edges of the diaphragm between the upper cup and the lower base (30) of the damper. As the solid or liquid pressurizing agent transforms to a gas, the pressure in the damper chamber increases to a predetermined level.</p> |
