OPEN/SHUT MEMBER FOR A DELIVERY VALVE

The present invention relates to an open/shut member for a delivery valve. The delivery valve is processed to adjust fuel injection pressure characteristics by adjusting a flow channel of fuel oil and the open/shut timing of the delivery valve, thus preventing cavitation. To this end, the open/shut...

Summary:The present invention relates to an open/shut member for a delivery valve. The delivery valve is processed to adjust fuel injection pressure characteristics by adjusting a flow channel of fuel oil and the open/shut timing of the delivery valve, thus preventing cavitation. To this end, the open/shut member for a delivery valve has a contact surface on which a first chamfered portion is chamfered in a vertical direction to change the flow channel of fuel. La présente invention a trait à un élément d'ouverture/de fermeture destiné à un clapet de refoulement. Le clapet de refoulement est traité de manière à ajuster les caractéristiques de pression d'injection de carburant en ajustant un canal d'écoulement de mazout et le minutage d'ouverture/de fermeture du clapet de refoulement, ce qui permet de la sorte d'empêcher toute cavitation. Pour ce faire, l'élément d'ouverture/de fermeture destiné à un clapet de refoulement est doté d'une surface de contact sur laquelle une première partie chanfreinée est chanfreinée dans la direction verticale de manière à changer le canal d'écoulement de carburant.
