Abstract

Die Erfindung bezieht sich auf eine Hochdruckpumpe zur Versorgung von Verbrennungskraftmaschinen mit Kraftstoff, an deren Gehäuse (2) eine Verstelleinheit (5) zum Verschieben des Einspritzzeitpunktes aufgenommen ist. Die Verstelleinheit (5) umfasst einen Einspritzverstellerkolben (6) mit Zulaufbohrungen (10,11), wobei im Einspritzverstellerkolben (6) ein Regelschieber (12) bewegbar aufgenommen ist, welcher an seiner einem Kaltstartbeschleunigungskolben (23) zuweisenden Seite (18) mit einer Vorspannkraft beaufschlagt ist. Zwischen dem Kaltstartbeschleunigungskolben (23) und der zweiten Stirnseite (18) des Einspritzverstellerkolbens (6) ist ein diesen direkt beaufschlagendes Federelement (62) sowie ein von diesem Federelement (62) unabhängiges, auf den Regelschieber (12,20) einwirkendes, an einem Träger (55) aufgenommenes Federpaket (60,61) angeordnet.
