Abstract

A fuel injector for internal combustion engines having a control valve arranged upstream of a main flow valve is configured so that the connection leading over the control chamber between the inlet and outlet, which is regulated by the valve member of the control valve, directs the function of a throttle position, among other things, by way of a limit stop of the control piston against the front wall overlapping the control chamber for the purpose of reducing control leakage.
