Abstract

L'invention concerne un système d'alimentation en liquide qui permet de raccourcir le temps passé au pré-refroidissement et permet de fournir efficacement un liquide. Le système selon l'invention est caractérisé en ce qu'il est équipé d'un premier passage d'écoulement qui passe d'une ouverture d'entrée (130b) à une première chambre de pompe (P1) et à travers lequel un liquide à ultra-faible température s'écoule vers une ouverture de distribution (130c), et d'un second passage d'écoulement qui passe de l'ouverture d'entrée (130b) à une seconde chambre de pompe (P2) et à travers lequel le liquide à ultra-faible température s'écoule vers l'ouverture de distribution (130c), et en ce que la hauteur de la position à laquelle le premier passage d'écoulement passe d'une orientation vers le haut à une orientation vers le bas dans une direction verticale et la hauteur de la position à laquelle le second passage d'écoulement passe d'une orientation vers le haut à une orientation vers le bas dans une direction verticale sont identiques.
