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： A fuel injection nozzle for directly injecting fuel into a cylinder of an internal combustion engine is inserted in a connecting pipe extending from a fuel rail and is fixed to the connecting pipe by fastening member. The fuel injection nozzle has a sealing part for sealing a fuel passage to prevent fuel leakage, and a contact part in contact with the fastening member. The contact part is softer than the fastening member, and the contact part undergoes plastic deformation when a bending moment that bends the axis of the fuel injection nozzle acts on the fuel injection nozzle.

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： 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.

摘要： An injector used for an internal combustion engine includes a valve needle which closes a fuel passage by contacting a valve seat and opens the fuel passage by separating from the valve seat. A coil and a magnetic core are provided to drive the valve needle, and an anchor is held in a relatively displaceable state with respect to the valve needle. A first biasing device biases the valve needle in a direction opposite to a direction of a drive force, and a second biasing device biases the anchor in the direction of the drive force with a set load smaller than that of the first biasing device. A restricting feature restricts relative displacement of the anchor with respect to the valve needle in the direction of the drive force.
