Abstract

La plaque de réglage 10 est montée en sandwich entre le toc d'entraînement 2 et le rotor distributeur 13 formant corps de pompe; des échancrures prévues dans cette plaque permettent d'y loger des cales dont l'épaisseur est légèrement supérieure à celle de la plaque; un axe traversant le toc d'entraînement porte intérieurement un maneton excentré qui s'engage dans une encoche de la plaque et extérieurement un levier coudé portant une masselotte sur un bras et un faible ressort sur l'autre bras; le moteur étant à l'arrêt, la masselotte est proche de l'arbre d'entraînement sur lequel porte ledit faible ressort, ce qui assure la surcharge du moteur; quand la vitesse du moteur atteint sensiblement le régime du ralenti, la force centrifuge écarte la masselotte et le maneton excentré entraîne la plaque pour supprimer la suralimentation.The adjustment plate 10 is sandwiched between the drive toc 2 and the distributor rotor 13 forming the pump body; notches provided in this plate make it possible to accommodate therein shims whose thickness is slightly greater than that of the plate; an axis passing through the drive lock carries an eccentric crank pin on the inside which engages in a notch of the plate and an elbow lever on the outside carrying a weight on one arm and a weak spring on the other arm; with the engine stopped, the weight is close to the drive shaft on which said weak spring bears, which overloads the engine; when the engine speed substantially reaches idle speed, the centrifugal force moves the flyweight apart and the eccentric crankpin drives the plate to suppress the supercharging.
