Abstract
Pompe à pistons de course variable. Pompe à pistons cylindriques creux coopérant avec un plateau oscillant monté pivotant sur un arbre moteur. L'inclinaison du plateau est modulée au moyen d'une pression pilote agissant sur un piston différentiel et d'un mécanisme interposé entre le piston et le plateau. L'effort de poussée axial est pratiquement totalement encaissé par un arrangement formant palier hydrostatique, ce qui permet d'utiliser des paliers à billes ordinaires pour le montage de l'arbre moteur. Application aux pompes pour carburant destinées à l'alimentation de moteurs diesel.
