Patent ID: 8156961

Claim:
An assembly comprising a tank for storing pressurized gas and a device for controlling the filling of and/or the tapping-off from said tank, the tank comprising an orifice allowing communication with the inside of the tank, a filling and distribution head positioned at the orifice and comprising a pre-regulating device at least partially incorporated into the volume of the tank, a connection interface configured to be capable of collaborating for attachment and removal with the device for controlling the filling of and/or the tapping-off of gas, wherein the head further comprises an isolating member at least partially housed inside the volume of the head and accessible to an opening member outside the head via an access orifice formed in the head, the control device comprising a body provided with a connection end adapted to collaborate for removable attachment with the connection interface, the opening member able to move relative to the body, an actuating element able to move the opening member selectively between a retracted rest position and a work position in which one end of the opening member projects out from the body beyond the connection end so as to allow the opening member to dip down inside the access orifice in the head in order to open the isolating member and, wherein the device for controlling the filling and/or the tapping-off comprises an inlet orifice for the gas tapped off from the tank, a first safety valve and a member for regulating the pressure of the tapped-off fluid, the first safety valve and the pressure-regulating member being connected in parallel to the inlet orifice.
