Fuel injection valve
摘要:
A fuel injection valve, in particular for fuel injection systems of internal combustion engines, includes a magnet coil, an armature acted upon in a closing direction by a return spring, and a valve needle, in nonpositive engagement with the armature, for actuation of a valve closure element that, together with a valve seating surface, forms a sealing fit. At least one fuel conduit through which fuel flows is provided in the armature and/or in the valve needle. An impact element is mounted on the valve needle in the spray-discharge direction of the fuel conduit.
