Definitions

  • the invention relates to a gas distribution assembly comprising a gas container, such as a cylinder for gas, in particular for medical gas, a valve unit with an integrated expansion system fixed on the gas container, a protective cover arranged around of the valve unit to protect it from shocks and dirt and a pressure or autonomy indicator device arranged so as to reduce the risk of pressure reading error in particular, thanks to increased flexibility in the positioning of the elements subjected to high pressure.
