Abstract
L'invention concerne une pompe à palettes pour un fluide compressible doté d'un carter (4) étanchéifié comprenant une chambre de pompe (6), le carter (4) étant sensiblement composé d'une partie bride (8), d'une partie circonférentielle (10) et d'une partie couvercle (12), un arbre de rotor (14) doté d'une unité rotor (18) comportant au moins un élément coulissant (20) étant monté de manière à pouvoir tourner dans la partie bride (8), de telle manière que l'unité rotor (16) divise la chambre de pompe (6) en au moins deux chambres partielles (5, 7) et envisage l'établissement d'une pression/dépression, la partie couvercle (12) étant mobile dans la direction axiale de l'arbre de rotor (14), de telle manière qu'en cas de pression trop élevée dans une chambre partielle (5, 7), une décompression s'effectue du fait d'une liaison fluidique par rapport à la chambre partielle (5, 7) voisine.
