Abstract

A fuel injection valve for a high-pressure injection of fuel from a central high-pressure reservoir into combustion chambers of an internal combustion engine, wherein, by means of an inlet throttle bore, the high-pressure reservoir is operationally connected to a control chamber which controls the opening and closing of the fuel injector, and wherein the control chamber communicates with an on-off valve by means of an outlet throttle bore. The inlet throttle bore is aligned eccentrically in relation to the control chamber.
