Abstract

  • 1. Brennstoffeinspritzvorrichtung für Dieselbrenn­ kraftmaschinen, mit mindestens einem Pumpenplunger 4, der in einer Plungerbüchse 5 dichtend geführt ist und zusammen mit der Plungerbüchse 5 einen Hochdruckraum 11 bildet, der während der Abwärtsbewegunge des Plungers von Brennstoff durch ein Steuerelement mit einem Niederdruckraum 13 ver­ bunden ist, wobei der Hochdruckraum 11 über eine Einspritz­ leitung 48 in Strömungsverbindung mit einem Einspritzventil 49 steht.
  • 2.1 Der Erfindung liegt die Aufgabe zugrunde, den schädlichen Raum der Brennstoffeinspritzvorrichtung so klein wie möglich zu gestalten, um dadurch hohe Einspritz­ drücke verwirklichen zu können.
  • 2.2 Diese Aufgabe wird erfindungsgemäß gelöst durch eine dauernd offene Strömungsverbindung zwischen dem Hochdruckraum 11 und dem Einspritzventil 49.
