Abstract
Fuel injection valve having a magnet armature () which interacts with a valve seat (), which is formed on a valve piece (), in order to open and close an outflow opening (), wherein the magnet armature () can be moved away from the valve seat () by an electromagnet (). A valve piece () delimits a control chamber (), wherein the outflow opening () opens into the control chamber (), and the control chamber () can be charged with fuel at high pressure that exerts a hydraulic force on the valve piece (). Between the magnet armature () and the valve piece (), there is arranged a bracing element () which is preloaded against the valve piece () and which exerts a force on the valve piece () in the region of the outflow opening () in the direction of the control chamber ().
