    摘要： An electromagnetic fuel injection valve device for an internal combustion engine is configured to carry out an energization to an electromagnetic coil of an injection valve actuator for a valve opening motion and additionally carry out a mid-term energization at a time interval between both an energization for valve opening of a previous fuel injection and an energization for valve opening of a subsequent fuel injection. A current of the mid-term energization is smaller than a current of the energization for valve opening motion and has the same direction as a direction of the current of the energization for valve opening motion.

    摘要： The present invention provides a simplified fuel injector which uses fuel as hydraulic oil to intensify the injection pressure.A pressure intensifier of the fuel injector is provided with a pressurization piston 106, a first fuel chamber 107 that communicates with a fuel inlet passage 101 (or a fuel supply passage), and a fuel pressurization chamber 111. The pressurization chamber 111 is provided inside a valve body 110. The pressurization piston 106 is formed displaceably relative to the valve body 110 and is provided with a first pressure receiving surface 106a and a pressurization piston portion 106b. The first pressure receiving surface 106a is one end surface of the pressurization piston 106 which faces one of the piston displacement directions 106d, that is, faces the first fuel chamber 107. The pressurization piston portion 106b is provided on the other end surface of the piston 106 which faces the other direction of the piston displacement directions 106d, that is, faces the pressurization chamber 111. The area of the pressurization piston portion 106b which faces the pressurization chamber 111 is smaller than that of the first pressure receiving surface 106a, and the pressurization piston portion 106b serves to change the volume of the pressurization chamber 111.

    摘要： In a fuel injection valve, it is intended to enhance valve-closing responsivity while maintaining durability (anti wear property) of a collision portion between a stationary core and a movable core and valve-opening responsivity.An annular end face 106A of the movable core 106 in the fuel injection valve is provided with a collision portion 106C that collides to a stationary core 107 when the movable core is magnetically attracted toward the stationary core side and a non-collision portion that keeps a fluid gap between both cores at an area of an outer side or an inner side from the collision portion. The annular end faces of the stationary core and the movable core are coated with platings 30, 31 having anti wear property, and at least one of the platings of the stationary core and the movable core is formed in such a manner that the thickness thereof at the collision portion 106C is to be thicker and the thickness thereof at the non-collision portion is to be thinner.

    摘要： An injector used for an internal combustion engine, wherein force acting on a valve element due to flow of fuel is reduced. The shape of either a valve element front end or a valve seat surface of a fuel injection valve is adapted such that the distance between the valve element front end and the valve seat surface which is formed by a circular conical surface is greater than in the case when the shape from a valve element circular tube surface to a spherical surface which forms a seat is connected by a circular arc. As a result, the cross-sectional area of a flow path is rapidly increased from the valve seat surface, on the outer side of the valve element, and this reduces that portion of the valve element which receives pressure due to a reduction in static pressure, reducing force acting on the valve element.
