    摘要: Step portions in a core and a valve holder are provided, and an L-shaped sleeve is fitted in these step portions. This construction axially shortens the coextensive portion of the outer circumference of the armature and the inner circumference of the sleeve. The length of the armature is also relatively shortened.

    摘要: The fuel injection system includes an injector 7 to be electromagnetically driven, a control device 2 for outputting a drive signal having first current-carrying time T1 and second current-carrying time T2 to this injector 7, and a drive device 6 for passing a large current to open a valve of the injector 7 during the first current-carrying time T1 and passing a small current to hold the injector 7 in a valve opening state during the second current-carrying time T2. The system is constructed so that the first current-carrying time T1 is set to the time shorter than valve opening required time T0 from a current-carrying start of the injector 7 to full opening and this time difference is set to the value shorter than valve closing operation delay time from a current break of the injector 7 in the case of breaking a current in the first current-carrying time T1 to a start of a valve closing operation.

    摘要: An air fuel mixing portion 5A in an air fuel assist type fuel injection valve comprises an upstream cylindrical portion including an air injection opening and a tapered downstream portion whereby dripping of fuel can be minimized. A spray angle of 30.degree. or less is obtainable, and a rate of change in fuel flow between an air-injection time and a non-air-injection time can be reduced. Further, the relation between the inner diameter D.sub.1 of the cylindrical portion and the smallest diameter of the tapered portion is determined to be D.sub.1

    摘要: A current driven D/A converter sets an OFF control voltage (BIAS3) for turning off NMOS transistors M12P, M12N, M22P, M22N, M32P and M32N at a voltage close to an ON control voltage (BIAS2). This makes it possible to reduce the swing of the control voltage (ON control voltage−OFF control voltage) of the NMOS transistors, and hence to reduce the noise due to charge injections through parasitic capacitances, and noise of a ground voltage or power supply voltage due to flowing of discharge currents from the parasitic capacitances to the ground or power supply at turn off of the transistors, thereby being able to offer a high performance current driven D/A converter.
