Abstract:
1. 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, 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 device further comprises intermediate means that transmit the maintaining force to the locking means; the intermediate transmission means comprising a moving member that has a first end capable of collaborating in abutment with a coupling in the orifice and a second end capable of collaborating in abutment with the retractable locking means.
