ABSTRACT:
A gas charging head which is fitted atop the piston rod of an hydraulic damper. A force is applied to the charging head driving the piston rod back within the damper cylinder. As the piston rod moves in the cylinder, a seal penetrating device associated with the head displaces the piston rod seal. An annular path is formed between the piston rod and the inner surface of the penetrating device for communicating with a pressurized cavity in the charging head supplying gas under pressure to the internal volume of the damper.
