Abstract
A charging fixture for gas charging a damper includes a pair of body members adapted to be forced together under pressure. Alignment pins align the body members as they are forced together. Compressable elastomeric members define a cavity in the body members and are disposed in the body members and sized for compressing and deforming portions of an outer cylinder surface of the damper during charging. A passageway to the cavity is connected to a high pressure source of gas, and the damper is charged by gas entering from the cavity by displacement of a piston rod seal from along an intermediate cylinder head.
