Abstract
Device for filling and distributing gas comprising a body intended to be placed in the orifice of a pressurized-gas storage reservoir, a gas withdrawing circuit running between an upstream first end intended to be connected to the inside of the reservoir and a downstream second end intended to be connected to a user of the gas, the withdrawing circuit comprising a pressure regulator, a low-pressure chamber and an isolation valve positioned in series in that order from upstream to downstream, the low-pressure chamber being connected to a passage for discharging the gas to the outside of the device via a safety relief valve sensitive to the pressure in the low-pressure chamber and designed to close off the discharge passage when the pressure in the low-pressure chamber is below a first threshold, to open the discharge passage when the pressure in the chamber is higher than the first pressure threshold and below a second pressure threshold, and to close the discharge passage when the pressure in the chamber is higher than the second pressure threshold.

13. A gas filling and dispensing device comprising
a) a body intended to be placed in an orifice of a pressurized gas storage reservoir, b) a gas withdrawing circuit running between an upstream first end adapted for operable fluid connection to the inside of the pressurized gas storage reservoir and, c) a downstream second end adapted for operable fluid connection to a recipient gas container, wherein the withdrawing circuit comprises a) a pressure regulator, b) a low-pressure chamber and, c) an isolating valve, arranged in sequential series a)-c) from the upstream first end to the downstream second end, the low-pressure chamber in operable fluid connection to a passage in operable fluid connection to the outside of the device via a safety relief valve, wherein the safety relief valve is adapted to a) close the discharge passage when the pressure in the low-pressure chamber is below a first threshold, b) open the discharge passage when the pressure in the chamber is above the first pressure threshold and below a second pressure threshold, and c) close the discharge passage when the pressure in the chamber is above the second pressure threshold.
