Abstract
Process for emptying liquids and/or gases from a container, in particular from a shock absorber, in which a tool is used to penetrate the wall of the container to create a drain opening, whereby the tool is driven into the container by means of a pressure pulse. The pressure pulse is thereby generated by means of a controlled propellant charge inside a tool propellant chamber.
