Liquid hydrogen degassing device

A device for degassing liquid hydrogen circulating in a circuit, the liquid hydrogen being able to be stored in a storage tank and the circuit comprising a vertical degassing chamber with which three pipes communicate fluidically,

• an inlet pipe through which liquid flows from the storage tank to the vertical chamber, the inlet pipe comprising a mouth;
• a feed pipe for supplying a pump to which some of the liquid entering the vertical chamber through the inlet pipe flows;
• and
• a return pipe receiving another part of the liquid entering the vertical chamber through the inlet pipe,
• the device being characterized in that the cross-section of the vertical chamber at the level of the mouth of the inlet pipe for the arrival of the liquid in the vertical chamber is greater than the cross-section of the inlet pipe for the arrival of the liquid at its mouth, in that the ratio between these two cross-sections is greater than or equal to two, and in that a deflector is arranged in the vertical chamber opposite the mouth of the inlet pipe.
