| 摘要 | The invention relates to a fuel injection valve (16) for fuel injection systems in internal combustion engines, comprising a valve needle (3). A valve seat body (2) on said valve has a valve seat surface (1) which acts in conjunction with a valve closing body (5) to form a sealing seat (4). The fuel injection valve (16) also has a solenoid (6), an armature (8) which acts on the valve needle (3) and at least one fuel channel (9) in the armature (8) and/or the valve needle (3) for supplying the fuel to the sealing seat (4). The fuel channel (9) has a flow regulator valve (10) which restricts the flow of fuel through the fuel channel (9) more severely during a closing action of the armature (8) than during an opening action of said armature (8). In one embodiment of the invention, the flow regulator valve (10) is actuated by a magnetic field (11) induced by the solenoid (6) and an actuating element (14) consisting of ferromagnetic material. | ||||||
