Fuel injection valve for fuel injection systems of internal combustion engines comprises a valve seat body (5) having a valve seat surface (6) interacting with a valve closing body (4) to form a seal, and a spinning disk (35) upstream of the seal and having at least one spinning channel (36) spinning a fuel stream injected by the fuel injection valve and a through opening (43) penetrated by the valve closing body or a valve needle (3) connected to the valve closing body. An elastomer seal (32) is arranged between a guide sleeve (33) axially displaced on the valve closing body or the valve needle and the spinning disk. Preferred Features: A gap formed between the guide sleeve and the valve needle is hydraulically sealed.
