Fluid filling and/or extraction control device and tank including one such device

A device for controlling the filling and/or the extraction of fluid from a tank of pressurized fluid comprising:

• (a) a body having a connection end provided with attachment means intended to collaborate with a tank connection interface,
• (b) a member for opening a valve that can move relative to the body,
• (c) actuating means capable selectively of moving the opening member, the actuating means being able to move between an on position and an off position which correspond respectively to a work position and a rest position of the opening member,
• (d) an orifice intended to accommodate a removable inlet or outlet coupling for distributing fluid, and
• (e) retractable means of locking the actuating means in the on position, the retractable locking means being configured in such a way as to collaborate with the orifice in such a way that when a coupling is not connected to the control device in the orifice, the locking means are urged into their retracted position preventing the actuating means from remaining stably in the on position and, wherein the actuating means comprise a translationally mobile switch.

• wherein the retractable locking means are configured in such a way that when a coupling is connected to the control device in the orifice, a lock activation element transmits a force to the locking means so as to maintain the latter in an active position that locks the actuating means in the on position and, wherein the locking means comprise an elastic attachment portion, the elastic attachment portion and the actuating means having mating shapes so that when the locking means are in the active locking position the movement of the actuating means toward the on position causes the elastic attachment portion to become attached to the actuating means.
