Abstract

The container is influenced by a constant force in order to impart a constant pressure to the gas in the container within predetermined limits. Gas at this constant pressure is taken from the container and can be fed to a breaking circuit in the breathing or anaesthesia system. The container is so formed that it produces the constant force automatically. The container (1) is at least partly made of an elastic material, e.g. metal or plastics, the constant force being produced by the elasticity of the material. The container is a bellows with at least one folded wall (23), which at least partly is of the elastic material. At least this part of the fold (24) is so formed that the wall automatically presses itself together.
