A thermally activatable safety valve for a pressure vessel includes i) a pressure relief unit having a valve for pressure relief of the pressure vessel; ii) at least one release line which extends away from the pressure relief unit; and iii) at least one bursting device. The release line, the bursting device and the valve are fluidically connected and form a common fluid system. The valve is designed, for pressure relief, to pass from a first closed position into a second open position if the pressure in the fluid system is less than an actuating limit pressure. The bursting device is designed to bring about pressure relief in the fluid system if the pressure in the fluid system exceeds a release pressure.

A filling station for pressurized fluids has a storage container and a dispenser supplied thereby, comprising a high-pressure path and a low-pressure path. The storage container is partitioned into separate sections, which are each connected to the input of a high-pressure pump via a first switching valve and to the output of said high-pressure pump via a second switching valve. The first or second switching valves are connected on their pump sides to the low-pressure path of the dispenser via a third switching valve. The output of the high-pressure pump supplies a high-pressure reservoir via a fourth switching valve, which high-pressure reservoir is connected to the high-pressure path of the dispenser via a fifth switching valve.

The shell of the LNG tank is substantially surrounded by insulation. The LNG tank has at least one bellow connection surrounding at least part of the length of the at least one pipe for connecting the at least one pipe extending from the LNG tank to the tank connection space. A system for connecting at least one pipe between an LNG tank and a tank connection space thereof is also provided. At least one pipe extends from the LNG tank to the tank connection space and which LNG tank is a single-shell tank having one shell. The at least one pipe is connected between the LNG tank and the tank connection space by at least one bellow connection.

A base for a pressurized gas tank, such as hydrogen, is substantially circular about an axis, and comprises a substantially cylindrical pipe of axis, which passes through the base in order to connect an outside of the tank to an inside of the tank. A substantially tubular notch of axis is arranged on an inner side of the tank and is suitable for receiving a sealing envelope. A substantially tubular sleeve of axis is arranged on the inner side of the tank and has an inner diameter substantially equal to a diameter of the pipe and an outer diameter substantially equal to an inner diameter of the notch, and also has an axial extension at least equal to that of the notch. An O-ring and a groove of axis, capable of receiving the O-ring, are arranged in a side wall of the notch. The base also comprises a body and a substantially tubular ring of axis, interfaced by a surface of revolution about the axis passing through the groove.

The invention relates to a method for detection of a leak from a tank for liquid gas, said tank comprising a membrane surrounding the liquid gas, the membrane being surrounded by an insulation space which separates the membrane from a wall, the insulation space being filled an inert gas which is injected and extracted by at least one duct. The detection method comprises the following steps: determining 921 a first variation of mass of inert gas ΔM1 between two moments by measuring the gas added and removed by the duct; calculating 922 a second variation of mass of inert gas ΔM2 corresponding to a difference between two masses of inert gas measured in the insulation space; and comparing 931 the first variation with the second variation, and triggering an alarm if a difference E1 between the first variation and the second variation of mass of inert gas is greater than a first threshold S1.
