| 摘要 |
This device comprises: a compression unit (4) having a plurality of stages, said unit being supplied with gas from the cryogenic tank (2) and delivering gas at an engine supply pressure, a reliquefaction system (20) having an outlet for liquid to the cryogenic tank (2), and an exchanger (10) arranged between the cryogenic tank (2) and the compression unit (4), in order to heat the evaporation gas coming from the tank (2) before it enters the compression unit (4). The evaporation gas coming from the cryogenic tank (2) is heated by gas compressed inside the compression unit (4) to a pressure lower than the engine supply pressure. The reliquefaction system (20) is supplied with gas compressed inside the compression unit (4) to a pressure lower than the supply pressure of the engine. |
