The invention relates to a gas-dispensing device for connecting a plurality of pressurized gas sources (E1, E2, E3, E4) to a user, the device including a housing provided with a plurality of gas inlets to be connected to respective gas sources (E1, E2, E3, E4) and an outlet to be connected to a user
The invention relates to a gas-dispensing device for connecting a plurality of pressurized gas sources (E1, E2, E3, E4) to a user, the device including a housing provided with a plurality of gas inlets to be connected to respective gas sources (E1, E2, E3, E4) and an outlet to be connected to a user member, a dispensing member that selectively movable, relative to the body, into separate dispensing positions for selectively putting each inlet in communication with the outlet in turn, while the other inlets are isolated from the outlet, characterized in that the device comprises an emergency discharge system that is movable into an operative position in which all the gas inlets are simultaneously forcedly connected to a gas discharge outlet.

1. A gas-dispensing device for connecting a plurality of pressurized gas sources sequentially to a user, the device comprising: a housing provided with a plurality of gas inlets intended to be connected to respective gas sources;an outlet intended to be connected to a user member, wherein a dispensi
1. A gas-dispensing device for connecting a plurality of pressurized gas sources sequentially to a user, the device comprising: a housing provided with a plurality of gas inlets intended to be connected to respective gas sources;an outlet intended to be connected to a user member, wherein a dispensing member is selectively movable relative to the body into distinct dispensing positions permitting each inlet to be brought into communication selectively and in turn with the outlet while the other inlets are isolated from the outlet; andan emergency discharge system capable of displacement into an active position in which all the gas inlets are brought simultaneously into a forced relationship with a gas discharge outlet, wherein the emergency discharge system is capable of displacement from a neutral position towards the active position, wherein: in the neutral position, the emergency discharge system allows the selective displacement of the dispensing member into the dispensing positions in the sense that, in the active position, the emergency discharge system displaces the dispensing member into a disengaged position preventing the dispensing positions;the dispensing member is forced by a resetting member towards the disengaged position;in the neutral position, the emergency discharge system forms a removable stop preventing the displacement of the dispensing member towards the disengaged position; andthe emergency discharge system includes a thermal fuse. 2. The device of claim 1, wherein the emergency discharge system includes an actuator that is selectively movable manually or by electromechanical means. 3. The device of claim 2, wherein the actuator is capable of translational displacement and includes one extremity projecting beyond the housing for its actuation. 4. The device of claim 1, wherein the dispensing member is capable of rotational movement relative to the body, the dispensing positions being defined by respective angular positions of the dispensing member in relation to the body and to the inlets. 5. The device of claim 1, wherein the dispensing member is capable of translational displacement relative to the body towards the disengaged position. 6. The device of claim 1, wherein the dispensing member includes an internal channel having a downstream extremity in communication with the outlet and an upstream extremity likely to be brought into communication with one or all the inlets depending on the position of the dispensing member relative to the body. 7. The device of claim 1, wherein the emergency discharge system consists of a thermal fuse consisting of a metallic eutectic having a predetermined melting temperature between 85° C. and 120° C. 8. The device of claim 1, wherein the housing consists of a single piece or a plurality of assembled pieces. 9. The device of claim 1, wherein the gas discharge outlet coincides with the outlet intended to be connected to a user member of the gas. 10. The device of claim 7, wherein the metallic eutectic has a predetermined melting temperature between 105° C. and 115° C. 11. A gas-dispensing installation on the basis of a plurality of pressurized gas sources utilized sequentially to supply a user, the installation comprising a dispensing device in accordance with claim 1, said pressurized gas sources being connected fluidly respectively to the gas inlets of the housing, the user being connected fluidly to the outlet of the housing.
