Abstract

L'invention concerne un compresseur à vis, destiné à être utilisé en particulier dans un véhicule, ce compresseur à vis présentant un carter d'huile (1) pourvu d'un dispositif d'atténuation des fluctuations du niveau d'huile. L'objectif de l'invention est de mettre au point un compresseur à vis dans lequel le dispositif d'atténuation des fluctuations du niveau d'huile est amélioré par rapport à l'état de la technique. À cet effet, le dispositif d'atténuation des fluctuations du niveau d'huile présente un dispositif barrière empêchant que le niveau de l'huile s'élève le long d'une paroi du carter du compresseur à vis.
