Abstract
Le compresseur à spirales comporte une unité de compression ; un arbre d’entraînement qui est orienté verticalement ; un agencement de palier inférieur (28) configuré pour supporter en rotation l’arbre d’entraînement ; et une pompe à huile (29) agencée au niveau d’une extrémité inférieure de l’arbre d’entraînement et configurée pour acheminer de l’huile vers l’unité de compression et vers l’agencement de palier inférieur (28). L’agencement de palier inférieur (28) comprend un carter de palier radial (34) comportant une surface de palier radial interne (37) entourant la portion d’extrémité inférieure de l’arbre d’entraînement ; des paliers de butée axiaux supérieur et inférieur (43, 44) configurés pour limiter un mouvement axial de l’arbre d’entraînement ; et une chambre d’huile sous pression (51) en communication fluidique avec la pompe à huile (29), la chambre d’huile sous pression (51) étant au moins partiellement délimitée par la surface externe de la portion d’extrémité inférieure de l’arbre d’entraînement, la surface de palier radial interne (37) et les paliers de butée axiaux supérieur et inférieur (43, 44).
