Abstract

Bei einem Einspritzventil für Kraftstoff-Einspritzanlagen für Brennkraftmaschinen öffnet das Schließglied (7) in Rich­ tung des Brennraumes. Es hat eine zum Brennraum sich er­ weiternde Mantelfläche (8). Oberhalb des Schließgliedes (7) ist im Gehäuse (1) des Einspritzventils eine Drallkammer (18) vorgesehen, in der Kraftstoff infolge einer ständig offenen Rückflußverbindung zu einem Ventilauslaß (3) ständig rotiert.
