The invention relates to an element for controlling filling and/or drawing of a pressurized gas, to be mounted in an opening of a tank (1), comprising a body (21) provided with at least one device (8) for controlling the circulation of gas placed between a first end, which has an opening (31) forming an inlet and/or an outlet for the gas with regard to the tank, and a second end for communicating with the inside of the tank. The control element also comprises a safety gas escape device (5) for evacuating the gas from the reservoir in the event of a dangerous situation and comprises a channel or gas escape circuit (215, 213, 212, 211, 31) running between a first end (215) for communicating with the pressurized gas of the tank and a second end (31) for communicating with a user circuit or with the atmosphere, the escape circuit being closed or not according to the state of a safety element (52), characterized in that the second end of the gas escape circuit (215, 213, 212, 211, 31) coincides with the opening (31) of the control element forming an inlet and/or an outlet for the gas.
A member for controlling filling and/or drawing of a pressurized gas, said member being adapted and configured to be mounted in an orifice of a tank, comprising a body provided with at least one gas flow control device arranged between a first end, comprising an orifice forming an inlet and/or an outlet for the gas with respect to the tank, and a second end adapted and configured to communicate with the inside of the tank, the control member additionally comprising a gas escape safety device for evacuating the gas from the tank in the event of a risk situation and comprising a gas escape circuit extending between a first end, adapted and configured to communicate with the pressurized gas of the tank, and a second end adapted and configured to communicate with a user circuit or with the atmosphere, the escape circuit being either shut off or not depending on a state of a safety element, wherein the second end of the gas escape circuit coincides with the control device orifice forming the inlet and/or the outlet for the gas.
