Abstract

Die Erfindung bezieht sich auf eine Kraftstoffeinspritzeinrichtung für eine Brennkraftmaschine, mit einem über eine Hochdruckpumpe befüllbaren gemeinsame Hochdrucksammelraum (Common Rail). Der Hochdrucksammelraum ist mit Einspritzventilen verbunden, die jeweils ein als 3/2-Wege-Ventil ausgebildetes Steuerventil (2) enthalten. Am Steuerteil (2) sind Steuerflächen (5, 6; 19) vorgesehen, die eine Hochdruckversorgungsleitung (18) mit Zuleitungen (9, 9') zur Einspritzdüse (13) oder einer Entlastungsleitung (4) verbinden, wobei das Steuerteil (2) durch eine gesteuerte Abflußleitung (23) aktivierbar ist. Das Steuerteil (2) enthält ein Drosselelement (10), welches über eine Bohrung (11) mit einem Hohlraum (7) in Verbindung steht.
