ABSTRACT:
The invention relates to an injection valve for internal combustion engine fuel injection systems. The valve is designed to inject fuel into the intake manifold. The valve comprises a valve housing containing a core with which an armature cooperates. A nozzle body with a valve seat is connected to the valve housing. A sealing seat of a valve needle guided in the nozzle head cooperates with the valve seat. The valve needle includes a central blind bore. Metering openings designed to meter fuel quantities extend from the downstream end of this blind bore. At their opposite ends these metering openings discharge directly upstream of the sealing seat.
