Claims (4)

1. Pompe à vide à palette pour le fonctionnement de servoactionneurs dans des véhicules automobiles, notamment pour l'amplification de la force de freinage, avec les caractéristiques:
1.1 le rotor est monté en porte-à-faux et possède un guidage de palette radial (fente de guidage (6), palette (7));
1.2 le rotor présente un alésage intérieur qui s'étend au moins sur la largeur du rotor et qui est fermé à ses extrémités par des parois frontales, sa paroi frontale éloignée du palier étant formée par le fait que le rotor s'applique sur le couvercle voisin que comporte le corps de pompe;
1.3 l'alésage intérieur est relié à une conduite d'amenée d'huile lubrifiante (19), n'offrant qu'une quantité d'huile limitée de manière qu'une faible pression de l'huile lubrifiante s'établisse dans l'alésage intérieur,

caractérisée par le fait que l'alésage intérieur du rotor présente un trou d'étranglement (23) allant à l'atmosphère.
2. Pompe à vide à palette selon revendication 1,
caractérisée par le fait que la conduite d'amenée d'huile arrive dans l'alésage intérieur (21) du rotor par l'intermédiaire d'une liaison tournante pour liquide.
3. Pompe à vide à palette selon revendication 2,
caractérisée par le fait que le rotor est monté dans un palier lisse et par le fait que la liaison tournante pour liquide, pour l'amenée d'huile lubrifiante, se trouve dans la région du palier lisse, de préférence dans la région axialement médiane de celui-ci.
4. Pompe à vide à palette selon revendication 1,
caractérisée par le fait que la conduite d'amenée d'huile est agencée dans le couvercle de pompe (25) situé à l'extrémité libre du corps et débouche dans la surface frontale de l'alésage intérieur.
