ABSTRACT:
An injection valve for fuel injection systems in internal combustion engines is proposed, which serves to supply fuel into the intake tube of the engine. The injection valve includes a movable valve element, which cooperates with a fixed valve seat, downstream of which a guide bore is provided in a nozzle body. An insert is pressed into this guide bore. The insert has grooves which extend in an axial direction and serve the purpose of metering the fuel to be injected. The grooves may be embodied by faces, which can be reground in a simple manner in order to correct the injection quantity.
