Abstract

La présente invention concerne une machine de détente (0) comportant une zone d'admission (22) présentant un orifice d'admission d'un fluide de travail sous pression, ledit fluide étant constitué par un composant principal en phase gazeuse en régime de fonctionnement nominal chargé avec un composant lubrifiant en phase liquide. La zone de haute pression est constituée par la zone d'admission (22) alimentée directement par le fluide de travail sous pression. Le circuit de dérivation étant en contact avec la zone d'expansion (25) pour assurer un transfert thermique entre le fluide de travail circulant dans ledit circuit de dérivation et le fluide de travail contenu dans ladite zone d'expansion (25), pour former un moyen de préchauffe (15). La zone d'admission (22) présente : ? au moins une première ouverture interne débouchant dans une zone d'expansion (25) et ? une seconde ouverture interne débouchant dans ledit circuit de dérivation, commandée par ladite vanne (9).The present invention relates to an expansion machine (0) comprising an inlet zone (22) having an inlet port of a pressurized working fluid, said fluid being constituted by a main component in the gas phase in operating mode. nominal loaded with a lubricant component in liquid phase. The high pressure zone is formed by the inlet zone (22) supplied directly with the pressurized working fluid. The bypass circuit being in contact with the expansion zone (25) to provide heat transfer between the working fluid circulating in said bypass circuit and the working fluid contained in said expansion zone (25), to form a preheating means (15). The admission zone (22) presents:? at least a first internal opening opening into an expansion zone (25) and? a second internal opening opening into said bypass circuit, controlled by said valve (9).
