FUEL INJECTION VALVE

摘要

The invention relates to a fuel injection valve for fuel injection systems of internal combustion engines. The valve comprises an electromagnetic actuating element comprising a magnetic coil (1), a solid core (2), an outer magnetic circuit component (5) and a movable armature (17) for actuating a valve closing body (19) which interacts with a valve seat surface (16) provided on a valve seat body (15). The valve is characterized by extremely small outer dimensions. The entire axially movable valve needle (14), including the armature (17) and valve closing body (19), has a mass of only m <= 0.8 g. The valve is suitable as a fuel injection valve, in particular for use in fuel injection systems of mixture-compressing, spark-ignited internal combustion engines.
