Abstract

A safety device is provided for a gas distribution system in an airplane, containing at least one pressure regulator (5) between a pressurized gas source (2) and a supply line. Reliability of operation is improved with the provision of a pressure-limiting device (4) with two lines (41, 42) arranged in parallel with two pressure-limiting valves (43, 44, 45, 46) each arranged in the same direction in series. The pressure-limiting device (4) is arranged upstream of the pressure regulator (5).
