Abstract

Perfectionnement apporté à un piston de pompe à creusure latérale à section réduite, dans le but d'éviter la cavitation. Selon l'addition, la partie de rainure verticale 22 de la creusure 19 est élargie d'une valeur e' ce qui définit un décrochement 26 permettant la dispersion du jet du retour de fluide à la fin de chaque cycle de refoulement de la pompe. L'addition s'applique particulièrement pour les pompes d'injection de combustible dans les moteurs de combustion interne.
