Abstract

Die Erfindung bezieht sich auf ein Common Rail Einspritzsystem für Brennkraftmaschinen. Ein Common Rail Einspritzsystem besteht gewöhnlich aus Pumpe, Speicher, Einspritzleitungen und Injektoren. Erfindungsgemäß werden jedoch die Einspritzleitungen dadurch eingespart, daß der Speicher 1 unmittelbar über eine Pratze 3 und ein Druckrohr 8 an den Injektor 2 angeschlossen ist. Dadurch werden die Montagekosten spürbar reduziert und Defekte an den Einspritzleitungen vermieden. Für den Fall, daß dennoch größere Leckagen im Einspritzsystem auftreten sollten ist es vorteilhaft, zwischen Speicher 1 und Pratze 3 einen Durchflußbegrenzer 6 zwischenzuschalten.
