Abstract

Die vorliegende Erfindung betrifft eine Einspritzdüse für die direkte Einspritzung von Kraftstoff in den Zylinder einer Brennkraftmaschine mit innerer Verbrennung, aufweisend:- eine Düsennadel (9);- einen mit der Düsennadel (9) in Verbindung stehenden Kolben (11);- eine erste Drossel (13);- eine zweite Drossel (18);- ein Steuerventil (16).Kraftstoffverluste während der Einspritzung können dadurch wirksam vermieden werden, daß der Steuerraum (12) über eine weitere Zuleitung (15, 17) mit Hochdruckkraftstoff versorgt wird, in der ein Absperrorgan vorgesehen ist, das mit dem Steuerventil (16) gekoppelt ist, um bei geschlossenem Steuerventil (16) offen zu sein, und bei offenem Steuerventil (16) geschlossen zu sein.The invention relates to an injection nozzle for the direct injection of fuel into the cylinder of an internal combustion engine, comprising: - a nozzle needle (9); - a piston (11) connected to the nozzle needle (9); - a first throttle (13); - a second throttle (18); - a control valve (16) .Fuel losses during the injection can be effectively avoided by supplying the control chamber (12) with high pressure fuel via a further feed line (15, 17) a shut-off device is provided which is coupled to the control valve (16) in order to be open when the control valve (16) is closed and to be closed when the control valve (16) is open.
