Beschreibung
Zusammenfassung:	An electromagnetically actuatable valve, especially an injection valve for fuel injection systems which supply internal combustion engines with fuel, is proposed in which the fuel injection valve encompasses a valve chamber and a core upon which a magnetic coil is mounted by means of a carrier body. Fuel supply openings discharge into a flow passage provided around the magnetic coil. Vapor bubbles dissolved in the fuel may be flushed out of the flow passage via a first restriction into fuel return openings which communicate with a fuel return line. On the other hand, the fuel may flow from the flow passage into the collecting chamber which houses a valve component and a valve seat. Vapor bubbles which may appear near the valve component may be flushed out via a second restriction which is provided in the interior of a core to reach the fuel return openings. Thus, disturbances with fuel injection, especially during the "hot start" of the internal combustion engine, are avoided.
