1. A device for storing cryogenic fluid comprising:
a tank extending in a longitudinal direction and suitable for containing liquefied gas in equilibrium with a gas phase; and
a device for pressurizing the tank, the pressurization device comprising a pressurized gas generator fluidly connected to an injection rail configured to inject the generated pressurized gas that extends in a longitudinal direction in an upper portion of the tank from a first end thereof, through which the generated pressurized gas enters the injection rail via an inlet, and an opposite second end thereof, wherein:
at each one of a plurality of different longitudinal positions along the injection rail are disposed one or more outlet orifices, the different longitudinal positions being longitudinally spaced from one another;
means for improving uniformity of flow rates of the generated pressurize gas injected by the orifices in the longitudinal direction, wherein the means for improving uniformity of flow rates comprises one or more of the following: (a) the longitudinal spacing decreases in the longitudinal direction from the first end to the second end, (b) a diameter of the one or more orifices at the different longitudinal positions increases in the longitudinal direction from the first end to the second end; and
the pressurized gas generator comprises a heater for heating the liquefied gas withdrawn from the tank.
