Abstract

Es wird eine Kraftstoffeinspritzpumpe für eine Brennkraftmaschine beschrieben, die einen in einem Pumpenzylinder (1b) geführten Pumpenkolben (2) und einen von dem Pumpenkolben (2) begrenzten Druckraum (3) zur Förderung von Kraftstoff über einen Förderkanal (9) zur Zuführung in den Brennraum der Brennkraftmaschine aufweist. Zur Verstellung des durch eine in den Druckraum (3) mündende Steuerbohrungen (4a, 4b) überstreichende Steuerkante (6) des Pumpenkolbens (2) definierten Beginns der Kraftstoffeinspritzung ist erfindungsgemäß ein in einer Bohrung (10) verschieblich angeordneter Ausweichkolben (12) vorgesehen, welcher einen mit dem Druckraum (3) der Kraftstoffeinspritzpumpe in Verbindung stehenden Ausweichraum (18) begrenzt und über einen Ausweichhub s verschiebbar ist, wobei Mittel zur Verstellung des Ausweichhubs s des Ausweichkolbens (12) vorgesehen sind.
