Abstract

La présente invention concerne une pompe à haute pression présentant au moins un élément de pompe (32) qui comprend un piston de pompe (34) entraîné dans un déplacement de course par un arbre d'entraînement (12) de la pompe à haute pression. Ce piston de pompe (34) repose sur l'arbre d'entraînement (12) par l'intermédiaire d'un poussoir (50) qui est guidé mobile dans un alésage (52) d'un carter (10) de la pompe à haute pression. L'arbre d'entraînement (12) présente une section d'arbre (26) qui est excentrique par rapport à son axe de rotation (13) et sur laquelle une bague (28) est montée rotative, ladite bague étant adjacente au poussoir (50). Le poussoir (50) présente au moins sur une partie de sa surface une couche de protection anti-usure (60), dans sa zone de contact dans laquelle le poussoir (50) est adjacent à la bague (28) et/ou dans sa zone de contact dans laquelle le poussoir (50) est guidé dans l'alésage (52) et/ou dans sa zone de contact dans laquelle le poussoir (50) est adjacent au piston de pompe (34).
