In a fuel injection device for internal combustion engines, having a pump plunger driven via a drive cam and a pressure chamber disconnected from a pump chamber by an intermediate plunger that upon its working stroke always assumes the end positions, a pressure line that leads from the pressure chamber to an injection nozzle. A control valve in a supply line for low-pressure fuel metering, the supply line is connected, under the control of the pump plunger with the pressure chamber via a filling line during a first intake stroke segment, for an injection quantity metering that is also angle controlled, and toward the end of the intake stroke of the pump plunger, the supply line is connected to the pump chamber for a time-controlled metering that determines the injection onset.
