  1. Pompe du type gerotor comprenant un anneau lobé (12) qui engrène intérieurement avec un rotor lobé (16) ayant un plus petit nombre de lobes, tous les deux tournant autour d'axes parallèles (14,18) à l'intérieur d'une cavité cylindrique d'un corps de pompe (10), le dit corps comportant des orifices fixes d'entrée et de sortie (20,22) prévus sur l'axe de l'anneau et du rotor pour admettre du fluide dans les chambres de travail (30, 38) de la pompe qui se trouvent entre le rotor et l'anneau, et pour décharger du fluide à partir de ces chambres, les lobes du rotor et de l'anneau ayant sur leur longueur une forme en hélice,
    caractérisée en ce que
    les orifices d'entrée et de sortie sont disposés symétriquement par rapport à un plan contenant l'axe à la fois du rotor et de l'anneau, les deux orifices étant situés à la même extrémité axiale du rotor et de l'anneau, et l'angle de l'hélice étant tel qu'une extrémité de chaque lobe soit déphasée d'une valeur de 5 à 15 degrés par rapport à l'extrémité opposée de chaque lobe.
  2. Pompe du type gérotor selon la revendication 1, dans laquelle l'angle de déphasage est de l'ordre de 10 degrés.
