Abstract

L'invention porte sur un compresseur. Un compresseur à haut rendement comprend un trou d'admission (12) possédant une partie de diamètre réduit (12a) située sur le côté aval et une partie de diamètre agrandi (12b) située sur le côté amont. La longueur hors de contact allant de la partie d'extrémité distale aval d'une chemise d'entrée (13) à la partie de diamètre réduit (12a) est plus petite que la longueur de la partie de diamètre réduit (12a), une partie d'isolation thermique (16) est formée entre la chemise d'entrée (13) et la partie de diamètre élargi (12b), le diamètre intérieur φdC1 de la partie de diamètre réduit (12a) est égal au diamètre intérieur φdL de la chemise d'entrée (13), et une perte de pression peut être réduite au minimum pendant qu'un mouvement de chaleur entrant dans un gaz frigorigène d'entrée est supprimé dans un passage de conduit d'entrée par lequel le gaz frigorigène d'entrée est envoyé à une chambre d'entrée.
