Abstract

Cette pompe est du type à piston rotatif excentré portant des palettes radiales mobiles. Selon l'invention, chaque palette 9 est réalisée et disposée de manière qu'un dispositif de commande 17 dont est équipée la pompe puisse déplacer la palette, en vue de la mise en service et de la mise hors service de la pompe, entre une position où le centre de gravité de la palette est excentré d'un côté de l'axe de rotation 16 et où les forces centrifuges pressent la palette par son bord de travail 10 contre la surface de contact coopérante 6 et une position où le centre de gravité de la palette est excentré de l'autre côté de l'axe de rotation 16 du rotor 5 et où les forces centrifuges écartent la palette de la surface de contact 6. Une telle pompe peut notamment servir de pompe pour servofrein et être montée directement sur l'arbre d'une génératrice de véhiculee automobile.This pump is of the eccentric rotary piston type carrying movable radial vanes. According to the invention, each pallet 9 is produced and arranged in such a way that a control device 17 with which the pump is equipped can move the pallet, with a view to putting the pump into service and taking it out of service, between a position where the center of gravity of the pallet is eccentric to one side of the axis of rotation 16 and where centrifugal forces press the pallet by its working edge 10 against the cooperating contact surface 6 and a position where the center of gravity of the vane is eccentric on the other side of the axis of rotation 16 of the rotor 5 and where the centrifugal forces move the vane away from the contact surface 6. Such a pump can in particular serve as a pump for a brake booster and be mounted directly on the shaft of a motor vehicle generator.
