Abstract

Einspritzanlage für eine Brennkraftmaschine, mit einer Vorförderpumpe (12) zur Förderung von Kraftstoff aus einem Kraftstofftank (10), einer der Vorförderpumpe (12) stromabwärts nachgeordneten Hochdruckpumpe (14) zur Förderung des Kraftstoffs in einen Kraftstoffspeicher (16), einem der Hochdruckpumpe (14) stromabwärts nachgeordneten Drucksteuerventil (20), mit dem der in dem Kraftstoffspeicher (16) herzustellende Druck einstellbar ist, und mindestens einem dem Kraftstoffspeicher (16) stromabwärts nachgeordneten Injektor (18). Das Drucksteuerventil (20) ist stromabwärts des Kraftstoffspeichers (16) hydraulisch parallel zu dem Injektor (18) angeordnet.
