Abstract
A gas cylinder, in particular a high-pressure gas cylinder, includes a cylinder tube () having a piston rod () that is passed through a sealing arrangement () by which the gas pressure prevailing in the pressure chamber () of the cylinder tube () is sealed off against the ambient pressure. The sealing arrangement () has a compressed oil chamber () between a sealing element () adjacent to the pressure chamber () and another sealing element further away from the pressure chamber (). Oil can be pressed in the oil chamber by a supply device () at a pressure that is equal to or higher than the respective gas pressure prevailing in the pressure chamber () of the cylinder tube ().
