Abstract

Silencieux d'aspiration (1) pour un compresseur frigorifique (2) à enceinte hermétique, qui comprend un orifice d'entrée (3) pour faire pénétrer du fluide frigorigène dans le silencieux d'aspiration (1), et un orifice de sortie (4) pour faire sortir le fluide frigorigène du silencieux d'aspiration (1). Le silencieux d'aspiration (1) comporte également deux chambres (5, 6) pour absorber les sons, qui comportent chacune un fond (8, 9). Un élément de paroi (11) sert à séparer les chambres (5, 6) l'une de l'autre pour le fluide frigorifique dans la zone du fond (8, 9). L'invention vise à garantir que les chambres de silencieux (5, 6) soient dans l'ensemble le plus possible insonorisées et étanches au gaz. A cette fin, au moins un segment formant siphon (16) reliant les deux fonds dans la zone de l'élément de paroi (11), sert à recevoir de l'huile (14) dans une position de fonctionnement du silencieux d'aspiration (1). Le segment formant siphon (16) relie les deux chambres de silencieux (5, 6) l'une à l'autre pour l'huile (14) par l'intermédiaire d'un siphon.
