The present invention relates to a pressure boosting device for a cryogenic liquid fuel tank. In accordance with the present invention, the pressure boosting device, which is installed in a cryogenic liquid fuel tank to boost internal pressure by transferring fuel in the cryogenic liquid fuel tank and vaporizing the fuel and then re-introducing the fuel thereinto when the internal pressure becomes lower, includes: a first boosting transfer pipe in which the fuel in the cryogenic liquid fuel tank is introduced and transferred; a boosting module connected with the first boosting transfer pipe, receiving the fuel from the first boosting transfer pipe, and transferring the fuel through the movement of a magnet slider such that the fuel can be vaporized; and a second boosting transfer pipe connected to the boosting module and the cryogenic liquid fuel tank, and causing the fuel introduced from the boosting module to be vaporized while being transferred such that the fuel can be introduced into the cryogenic liquid fuel tank. Therefore, the present invention is capable of reducing a deterioration in the insulation performance of a fuel tank.

    본 발명은 초저온 액체 연료탱크용 승압장치에 관한 것으로, 본 발명에 따르면, 초저온 액체 연료탱크에 설치되어 내부압력이 낮아질 경우, 상기 초저온 액체 연료탱크 내의 연료를 이동시켜 기화시킨 후 다시 내부로 유입시켜 내부압력을 상승시키는 승압장치에 있어서, 상기 초저온 액체 연료탱크 내부의 연료가 유입되어 이동되는 제1 승압이동관; 상기 제1 승압이동관과 연결되어, 상기 제1 승압이동관으로부터 연료가 유입되고, 자석 슬라이더의 이동에 의해 연료를 이동시켜 기화가 이루어지도록 하는 승압모듈 및 상기 승압모듈과 상기 초저온 액체 연료탱크에 연결되고, 상기 승압모듈로부터 유입되는 연료가 이동되며 기화되어 상기 초저온 액체 연료탱크 내부로 유입되도록 하는 제2 승압이동관를 포함하는 승압장치를 제공할 수 있다.
