Abstract

L'invention porte sur une pompe volumétrique rotative avec aubes, qui comprend un corps (2), une chambre de pompage définie à l'intérieur du corps (2) par une paroi périphérique (3) ayant une forme cylindrique et une section transversale circulaire, et comprend un rotor (4) qui porte des aubes (5) et peut être entraîné en rotation excentrée à l'intérieur de la chambre de pompage, un élément annulaire apte à tourner librement (11) étant installé à l'intérieur de la paroi périphérique cylindrique (3) et définissant un espace de fonctionnement de pompe (C) dans lequel tourne le rotor portant les aubes (4), les parties d'extrémité des aubes (5) étant amenées en contact de glissement radial contre la surface interne de l'élément annulaire rotatif (11). De préférence, est laissée libre une cavité (12) entre la paroi de chambre de pompage (3) de la pompe et la surface externe de l'élément annulaire apte à tourner librement (11), et cette cavité (12) est placée en communication avec un raccord de distribution (10) de la pompe. Un disque apte à tourner librement (14) peut être placé entre au moins une extrémité axiale du rotor portant les aubes (4) et la paroi d'extrémité correspondante de la chambre de pompage, formant une cavité (15) qui est placée en communication avec un raccord de distribution (10) de la pompe. De préférence, la pompe est couplée à son propre moteur électrique (16) afin de l'entraîner.
