Abstract
A fuel injection device with a pump plunger which is driven in reciprocation and a working space which is enclosed by the pump plunger, and is connected to an injection valve connected directly to the pump housing. To control the fuel injection quantity and the injection instant, a solenoid valve is provided which is arranged in a fuel passage that is connected to the pump working space and serves for the filling and/or relief of the pump working space. To reduce the volumes subjected to the high pressure, the fuel passage is arranged in such a way that the fuel passage intersects the cylinder bore which accommodates the pump working space, and the solenoid valve is arranged at the entry of this passage.
