Abstract

The invention relates to an injection valve (10), particularly for the injection of fuel into the combustion spaces of internal combustion engines. The injection valve (10) comprises an anchor assembly which, in turn, has an anchor plate (20) and an anchor bolt (18). A seat (30) of the injection valve (10) is unblocked or closed off by the anchor assembly. The anchor plate (20) of the anchor assembly comprises a number of anchor wings (22), pairs of which have different inherent frequencies.
