Abstract

Dans la présente invention, un tuyau principal (77) relié à une conduite de liquide (60) et ayant un détendeur (78), et de multiples tuyaux de dérivation (81a, 81b, 81c) se ramifiant à partir de l'extrémité de sortie du tuyau principal (77) pour se connecter à des compresseurs (13a, 13b, 13c) et ayant chacun une soupape de réglage de débit (82a, 82b, 82c) sont prévus dans un circuit d'injection (81). Une unité de commande (100) est configurée, de sorte, pendant une opération d'injection, qu'elle maintienne à un degré d'ouverture fixe prescrit les soupapes de réglage de débit (82a, 82b, 82c) correspondant à des compresseurs prescrits (13a, 13b, 13c) des multiples compresseurs (13a, 13b, 13c), et règle les degrés d'ouverture de la soupape de compression (78) et des soupapes de réglage d'écoulement restantes (82a, 82b, 82c).
