Abstract
A fuel injection valve includes: a magnetic coil; an armature; and a valve needle connected to the armature for actuating a valve closing body which forms, together with a valve seat surface, a seal seat. Formed downstream from the valve seat surface is a spray opening that has, at the transition from a first to a second spray opening segment, a tear-off edge such that the complete opening angle of the spray opening at the tear-off edge is greater than 270° over the entire circumferential tear-off edge, so that, going out from the tear-off edge, on the floor of the second spray opening segment of the spray opening, there extends a circumferential floor region that is recessed behind the transition plane in which the tear-off edge is situated.
