Abstract

Un passage d'alimentation en huile de palier (70) qui est destiné à fournir une huile frigorigène à partir d'un carter d'huile (18) situé à l'intérieur d'un carter (15) aux paliers d'un arbre d'entraînement (60) est formé dans un compresseur à spirale (10). Une rainure de graissage (80) qui communique uniquement avec le carter d'huile (18) situé à l'intérieur du carter (15) par l'intermédiaire d'un passage de connexion (86) et d'un tube capillaire (87) est formée dans la face coulissante de poussée (35) du côté fixe de la spirale fixe (30). Le passage d'alimentation en huile de palier (70) et la rainure de graissage (80) ne sont pas connectés, de sorte que même si la spirale mobile (40) s'incline et que la pression dans la rainure de graissage (80) diminue, la pression dans le passage d'alimentation en huile de palier (70) ne diminue pas et l'huile frigorigène est fournie depuis le passage d'alimentation en huile de palier (70) jusqu'aux paliers de l'arbre d'entraînement (60).
