調量が不正確になつてしまう。2. Description of the Related Art When the electromagnetic coil is in an excited state, the mover does not directly contact the soft magnetic iron core, but the stop holder formed on the needle valve fixedly connected to the mover is fixed to the casing. Fuel injectors of the type that impact on the are known. DE-A 29 05 099 discloses that the stopper fixed to the above-mentioned casing is formed as a stopper plate. Therefore, even when the electromagnetic coil is in an excited state, a gap remains between the mover and the iron core, and magnetic attachment between the mover and the iron core caused by the residual magnetic action is avoided. However, since the adhesive force acts between the stopper plate and the stopper plate, which switch off the electromagnetic coil, the stopper member is delayed from being separated from the stopper plate. Due to this adhesion, the fuel metering of the fuel injection valve becomes inaccurate.

The interruption thus has the advantage that the adhesion between the stopper plate and the stopper is largely avoided. Furthermore, by interrupting the circular peripheral surface of the passage hole by means of the notch, the line of the peripheral surface of the passage hole which limits the contact area from the inside is increased, so that when the stopper shoulder approaches the stopper plate. , The fuel between the stopper shoulder and the stopper plate can flow out more quickly, and the contact surface area is increased by this increasing circumferential line when the stopper shoulder leaves the stopper plate. The fuel is quickly filled in the negative pressure region of. As a result, the fuel injection valve can quickly respond to the injection pulse.
