ABSTRACT:
In a known injection valve having a movable valve element and a valve seat face located in a nozzle body, a cup-shaped injection port insert is provided downstream of the valve seat face. In the novel injection valve, the object is to avoid warping of the injection port insert and to adapt the idle volume to requirements. To increase the rigidity of the injection port insert, the bottom of the injection port insert has a dishlike indentation, which is remote from the movable valve element, so that a collecting chamber is formed between the movable valve element and the bottom. The injection valve is particularly suitable for fuel injection systems in internal combustion engines.
