Abstract

Procédé permettant de régler la section de passage du capillaire. Il consiste à aplatir une partie 12 d'un tronçon de tube 10 raccordé à une source de pression constante jusqu'à ce que la pression à l'entrée du tube atteigne une première valeur, à cintrer ensuite le tube de fajon à ormer un segment arqué 60 prolongé de deux branches 62 divergentes dont on raccorde les extrémités 14 entre le condenseur et l'évaporateur 24 d'un circuit de réfrigération 16, et à régler ensuite couverture de l'angle que font les branches entre elles, à l'aide de moyens manuels ou automatiques 70, pour modifier la section du passage dans le segment 60 arqué de façon à régler le débit du tube 10. Application aux appareils de climatisation.
