Abstract: Vehicle for delivering inflammable fluid comprising a tractor unit and a tank mounted on a support, the vehicle including a fluid circuit connected to the tank that includes a set of pneumatic valves. The vehicle includes an electrical circuit having at least one electrical component and an electricity source connected to the electrical circuit via at least one port for connecting to a connection interface. A cover moves between a first position blocking access to the connection port(s) to prevent the electrical connection between the electricity source and the electrical circuit and a second position not blocking access to the connection port(s) to enable the electrical connection between the electricity source and the electrical circuit.

Abstract: Station for supplying a flammable fluid fuel comprising a first cryogenic tank (2) for storing fuel in the form of a cryogenic liquid, a second cryogenic tank (3) for storing an inert gas, a cooling circuit (4, 14) in a heat-exchange relationship with the first tank (2), the cooling circuit (4, 14) comprising an upstream end connected to the second cryogenic tank (3) for drawing cryogenic fluid from the second cryogenic tank (3) in order to give up frigories from the fluid of the second cryogenic tank (3) to the first tank (2), the station comprising a circuit (7) for withdrawing fluid derived from the second tank (3), characterized in that the cooling circuit comprises two pipes (4, 14) comprising an upstream end connected to the second tank (3), the two pipes (4, 14) each being provided with a respective exchanger (9, 10) housed in the first tank (2), the two exchangers (9, 10) being respectively situated in the upper and lower parts of the first tank.

Abstract: An installation for the storage of a liquified gas under pressure in a pressure chamber. The installation includes a closed pressure resistant chamber to contain the liquid. The container has a wall whose thickness es is determined by computations taking into account parameters associated with a pressure Ps within the chamber and a temperature Ts<−50° of the wall of the chamber. The installation further includes a device to indicate a magnitude G of a temperature Ts of the chamber wall and a device to indicate a magnitude G′ representative of the computation temperature Ts. The installation also includes a device to compare the magnitudes G and G′, and a device to lower the pressure to a value P2 below the computed pressure Ps if as a result of the comparison, Te is greater than Ts.
