Abstract
(DE)
Die Erfindung betrifft eine Kraftstoffhochdruckpumpe (16) zum Beaufschlagen eines Kraftstoffes mit Druck, wobei ein zwischen einem ersten, oberen Totpunkt (60) und einem zweiten, unteren Totpunkt (62) entlang einer Kolbenachse (24) beweglich angeordneter Kolben (20) sowie ein Stößel (10) mit einer im Wesentlichen senkrecht zu einer Stößelachse (40) angeordneten Traverse (36) zum Übertragen von kinetischer Energie von einem Stößelantrieb (66) auf den Kolben (20) in einem Kontaktbereich (68) von einer Traversenoberfläche (70) und einem Endbereich (42) des Kolbens (20) vorgesehen sind. In dem Kontaktbereich (68) weist der Kolben (20) einen kalottenförmigen Endbereich (74) und die Traverse (36) eine kalottenförmige Ausbuchtung (72) auf.
(EN)
The invention relates to a high-pressure fuel pump (16) for applying a fuel with pressure, wherein a piston (20) and a plunger (10) are provided, said piston being arranged such that it can move between a first top dead centre position (60) and a second bottom dead centre position (62) along a piston axis (24), and said plunger having a crosspiece (36), arranged substantially perpendicular to a plunger axis (40), for transmitting kinetic energy from a plunger drive (66) to the piston (20) in a contact region (68) of a crosspiece surface (70) and an end region (42) of the piston (20). In the contact region (68), the piston (20) has a dome-shaped end region (74) and the crosspiece (36) has a dome-shaped recess (72)
(FR)
L'invention concerne une pompe à carburant haute pression (16) servant à appliquer une pression à un carburant. Un piston (20) agencé de manière mobile le long d'un axe de piston (24) entre un premier point mort haut (60) et un second point mort bas (62), ainsi qu'un poussoir (10) muni d'une traverse (36) agencée sensiblement parallèlement à un axe de poussoir (40) pour transférer l'énergie cinétique d'un entraînement (66) du poussoir sur le piston (20), sont agencés dans une zone de contact (68) entre une surface (70) de la traverse et une zone d'extrémité (42) du piston (20). Dans la zone de contact (68), le piston (20) présente une zone d'extrémité (74) en forme de calotte, et la traverse (36) présente un creux (72) en forme de calotte.
