Abstract

La présente invention concerne une pompe d'alimentation haute pression qui présente un piston d'alimentation (14) guidé dans un cylindre haute pression. Ce piston d'alimentation est entraîné par un arbre d'entraînement (28) comprenant un excentrique (36) sur lequel une bague de roulement (40) bombée est montée rotative. Un élément de ressort (62) de type plaque est monté entre cette bague de roulement (40) et le piston d'alimentation (14) et est, par exemple, constitué par la partie inférieure (48) d'un poussoir à coupelle (46). Le piston d'alimentation (14) est, sur sa face (50), de forme concave, ce qui permet à l'élément de ressort (62) de pouvoir se plier dans la cavité (64) en fonction de la contrainte du piston d'alimentation (14). La surface de contact (54) de l'élément de ressort (62) avec la bague de roulement (40) et la surface annulaire (62), avec laquelle l'élément de ressort (62) repose sur le piston d'alimentation (14) sont ainsi plus grandes, ce qui permet de limiter dans un domaine acceptable la pression superficielle, même à de très hautes pressions de travail.
