Abstract

Die Erfindung bezieht sich auf ein Rückstromdrosselventil 1 und ein damit ausgestattetes Hochdruckeinspritzsystem. Das Rückstromdrosselventil 1 sitzt in einer Durchgangsbohrung 32 des Rails 30 und ist somit in dem Kraftstofffluss zwischen dem Railvolumen 31 und der zu dem Kraftstoffinjektor 35 führenden Injektorleitung 33 angeordnet.
