Abstract

L'invention concerne une pompe (110) à aube unique comprenant un stator (12), dans lequel est délimitée une chambre (14), et un rotor (116) qui tourne autour d'un axe de rotation (0-0). Le rotor (116) comprend une partie centrale cylindrique (116a) ayant un diamètre (D) prédéfini et des parties d'extrémité axiales cylindriques opposées (116b) ayant chacune un diamètre égal audit diamètre (D) prédéfini. Le rotor (116) est supporté rotatif dans la chambre (14) au niveau desdites parties d'extrémité axiales opposées (116b). Une aube (18) est montée coulissante dans une rainure (20) respective sensiblement radiale dudit rotor (116, 216). Le rotor (116) a une hauteur globale (H1) prédéfinie et un diamètre égal audit diamètre (D) prédéfini le long de ladite hauteur globale (H1). Le stator (12) comprend un corps de pompe (12a) et un couvercle (12b) qui fermer le corps de pompe (12a), le corps de pompe (12a) et le couvercle de fermeture (12b) étant pourvus de logements respectifs (122a, 122b) destinés à accueillir les parties d'extrémité axiales (116b) du rotor (116). Chaque logement (122a, 122b) comprend une surface d'appui axiale (123) destinée à une partie d'extrémité axiale respective (116b) du rotor (116). La distance axiale (H2) entre les surfaces d'appui axiales (123) desdits logements (122a, 122b) est supérieure à la hauteur globale (H1) du rotor (116).
