Abstract
Le système à compresseurs multiples (7) comprend une pluralité de compresseurs couplés en parallèle (8) ; des conduites de raccordement d’entrée (15) reliées chacune à un raccord d’aspiration de fluide frigorigène d’un compresseur (8) respectif ; des conduites de raccordement de sortie (17) reliées chacune à un raccord de refoulement de fluide frigorigène d’un compresseur (8) respectif ; une conduite d’équilibrage d’huile commune (18) et des conduites de raccordement d’équilibrage (19) reliant chacune la conduite d’équilibrage d’huile commune (18) à un raccordement d’équilibrage d’huile (21) d’un compresseur (8) respectif ; et des soupapes normalement ouvertes à ressort (25) étant agencées chacune dans une conduite de raccordement d’équilibrage respective (19) ou dans un raccordement d’équilibrage d’huile (21) d’un compresseur (8) respectif et étant configurées chacune pour se fermer lorsqu’une différence de pression entre une pression régnant dans le volume basse pression du compresseur (8) respectif et une pression régnant dans la conduite d’équilibrage d’huile commune (18) atteint une valeur prédéterminée.
