Abstract
An electromagnetically actuatable fuel injection valve for delivering fuel in internal combustion engines comprises a valve casing and an electromagnet core on which a coil carrier carrying a solenoid winding is mounted. The fuel inflow via the feed pipe can be directed past the armature and ejected via the valve seat, fuel passage and preparation bore. The solenoid wind is disposed in the interior cavity of the valve casing in such a manner that fluid can circulate thereabout. A blind bore in the valve casing serves as an accumulator for vapor-bubbles in the fuel which may flow back to the feed pipe via an exhaust line which connects with an annular groove and an exhaust outlet.
