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 ().

A device recovers energy in working machines with at least one power drive actuated to move a load mass back and forth and with an energy storage system () absorbing the energy released in the movement of the load mass in one direction and making it available for a subsequent movement in the other direction. The energy storage system includes an accumulator cylinder () mechanically coupled to the load mass and storing pneumatic pressure energy for movement in one direction. For movement in the other direction, the accumulator cylinder acts as an auxiliary working cylinder supporting the power drive and converting the stored pressure energy into driving force.
