Abstract

Eine Kraftstoffpumpe (10) umfasst einen Kolben (18) sowie Antriebsmittel (24) zum Antrieb des Kolbens (18). Der Kolben (18) ist in einem Zylinder (12) geführt, und ein Zylinderkopf (14) liegt am Zylinder (12) mit einer insgesamt ringförmigen Kontaktfläche (44) an. Mindestens ein Befestigungsmittel (58) beaufschlagt den Zylinderkopf (14) mit der ringförmigen Kontaktfläche (44) gegen den Zylinder (12). Um die Herstellkosten zu senken, wird vorgeschlagen, dass die ringförmige Kontaktfläche (44) und der Wirkbereich (64) des Befestigungsmittels (58) am Zylinderkopf (14) in Längsrichtung (66) des Zylinders (12) gesehen, im Wesentlichen auf gleicher Höhe liegen.
