Abstract
The invention relates to a pressurized gas dispensing device such as a tap, which includes a first end, to be placed in the opening of a pressurized gas storage tank, and a second end, including a connection interface selectively connectable to a device for controlling the filling and/or withdrawal of gas from the tank, the dispensing device including an internal gas circuit having an upstream end connecting inside the tank and a downstream end to be connected to said filling and/or withdrawal control device, the internal circuit including in series, upstream to downstream, a pressure regulator and a downstream insulation valve, the portion of the internal circuit located between the pressure regulator and the downstream insulation valve defining a so-called low-pressure chamber, the dispensing device; being characterized in that the connection interface includes at least one safety lock selectively movable between a first rest position, wherein the lock shapes the connection interface into a first configuration connectable to said combined filling and/or withdrawal control device, and a second active position, wherein the lock shapes the connection interface into a second configuration preventing connection to a combined filling and/or withdrawal control device, the safety lock being subject to the pressure in the so-called low-pressure chamber directly and/or via an intermediate transmission member such as a movable piston, the safety lock being moved to the active position thereof by the pressure in the low-pressure chamber when the pressure in the low-pressure chamber is greater than a predetermined threshold.

- 11. A pressurized gas dispensing, comprising a first end intended to be placed in the orifice of a pressurized-gas storage reservoir, and a second end comprising a connection interface that can be connected selectively to a device adapted to control the filling and/or the withdrawing of gas from the reservoir, the dispensing device comprising an internal gas circuit having an upstream end intended to communicate with the inside of the reservoir and a downstream end intended to be connected to the said filling and/or withdrawing control device, the internal circuit comprising, in series, from the upstream end downstream, a pressure regulator and a downstream isolation valve, a portion of the internal circuit that lies between the pressure regulator and the downstream isolation valve defining a low-pressure chamber, wherein the connection interface comprises at least one safety lock that can be moved selectively between a first rest position in which it configures the connection interface in a first configuration in which the device is connectable to the said mating filling and/or withdrawing control device and an active second position in which it configures the connection interface in a second configuration that prevents connection of the device to a mating filling and/or withdrawing control device, the safety lock being subjected to the pressure in the low-pressure chamber directly and/or via a moving piston, the safety lock being moved into its active position under the action of the pressure in the low-pressure chamber when the pressure in the low-pressure chamber is above a set threshold.
