Abstract

Kraftstoffeinspritzpumpe für Brennkraftmaschinen mit auf dem Pumpenkolben 3 über eine Regelstange 8 axial ver­ schiebbaren sowie verdrehbaren Steuerschieber 7 für die Ein­ spritzmengensteuerung und die Spritzbeginnsteuerung, wo­ bei auf der Regelstange 8 eine geschlitzte Nabe 9 lösbar fest­ geklemmt ist, die mit einem Mitnahmearm 34 zwischen zwei Wirkflächen 36,37 am Steuerschieber 7 greift und die eine Mitnahmeausnehmung 39 für die Drehverstellung des Steu­ erschiebers 7 aufweist, in die ein mit dem Steuerschieber 7 verbundener Zapfen 38 greift. Fuel injection pump for internal combustion engines with on the pump piston 3 via a control rod 8 axially ver slidable and rotatable spool 7 for the one spray quantity control and the spray start control where at the control rod 8 a slotted hub 9 releasably fixed is clamped with a driving arm 34 between two Active surfaces 36,37 on the control slide 7 engages and one Driving recess 39 for the rotary adjustment of the tax shifter 7, in which one with the control slide 7th connected pin 38 engages.
