Abstract

Abstract Translated from German Bei einem Einspritzventil, insbesondere für KraftstoffEinspritzanlagen von Brennkraftmaschinen, mit einer Magnetwicklung (7), einem Magnetkern (2, 3), einem Anker (13), welcher mit einem beweglichen Ventilteil (17) verbunden ist, das mit einem Ventilsitz (18) zusammenwirkt, sind Mittel (29) zur Erzeugung eines Dralls innerhalb des Einspritzventils derart angeordnet, daß sie im Kraftstoff-Kreislauf liegen und auch bei geschlossenem Einspritzventil von Kraftstoff durchströmt werden. Dadurch wird sofort bei Beginn eines jeden Einspritzvorganges eine gute Zerstäubung des Kraftstoffs bewirkt. In an injection valve, in particular for fuel injection systems of internal combustion engines, with a magnetic winding (7), a magnetic core (2, 3), an armature (13) which is connected to a movable valve part (17) which interacts with a valve seat (18) , means (29) for generating a swirl are arranged within the injection valve in such a way that they are in the fuel circuit and fuel flows through them even when the injection valve is closed. As a result, good atomization of the fuel is brought about immediately at the beginning of each injection process.
