Device for supplying pressurized fluid, and pressurized fluid cylinder(s) comprising such a device

A device for supplying pressurized fluid, comprising a first valve housing an internal fluid circuit, the device comprising a second valve comprising an internal circuit and forming a physical entity distinct from the first valve, the first and the second valve comprising respective coupling members forming a detachable male/female quick-connection system for the second valve on the first valve, the two valves being configured such as to place their internal circuits in communication when the second valve is coupled to the first valve via the quick-connection system, the internal circuits comprising an array of control valve(s) for controlling the circulation of the fluid towards an outlet the device comprising at least one manually actuatable movable command member for commanding the array of control valve(s) and/or the quick-connection system, the device comprising a member for purging one at least of the internal circuits, the purge member being in communication with the internal circuit or circuits on the one hand and with an exterior discharge zone, such as the atmosphere, on the other, the purge member being movable between a closed state preventing purging of the internal circuit or circuits towards the discharge zone and an open state allowing purging of the internal circuit or circuits towards the discharge zone, wherein the purge member comprises a check valve urged into a closure position against a seat by a return member, and in that the purge member can be actuated to its open state by the at least one manually actuatable movable command member, wherein the at least one manually actuatable movable command member capable of actuating the purge member comprises a member that is movable in translation and/or in rotation such as to command the locking/the unlocking of the mechanical link of the coupling members of the quick-connection system.
