ABSTRACT:
An electromagnetically actuatable valve is proposed, in particular a fuel injection valve for fuel injection systems in internal combustion engines, which by using a resilient element between a valve housing and a collar of a spacer ring exerts a long-lasting pressure upon a guide diaphragm that radially guides a valve element. In this manner, an exact fixation of the valve element on a valve seat when the valve is closed is assured even if long-term strain on the injection valve results in a slight loosening between a nozzle holder that includes the valve seat and the valve housing.
