Abstract

L'invention concerne un rotor fritté pour une pompe, notamment une pompe à vide, comportant un corps de base de rotor présentant une section de palier frittée et une section de réception d'ailette, pourvue d'au moins une fente de réception d'ailette. L'invention est caractérisée en ce que la fente de réception d'ailette est délimitée par un corps de palier connecté d'un seul tenant au corps de base de rotor fritté, présentant une autre section de palier frittée.
