Abstract
A hydraulic shock absorber is formed as a sealed assembly and subsequently, at a desired time, an opening is non-contaminantly pierced in the outer shell and the shock absorber is pressurized by passing a pressurized fluid through the opening and the opening is then non-contaminantly sealed with a metal ball by welding to make the hydraulic shock absorber permanently gas pressurized. The shock absorber assembly, the method of making it and the apparatus for making it are disclosed in this specification.
