Abstract (en)
[origin: DE10233099A1] A high-pressure fuel pump has first (18) and second (118) pumping pistons (PP) that are driven by an internal combustion engine with a stroke motion and border a pumping work area (22) fed with fuel from a fuel reservoir (24). The second PP slides almost coaxially in the first PP. A second injection valve element (IVE) (128) slides inside a first IVE (28) and is impacted directly by the predominant pressure in a control pressure chamber (52).
