摘要： In a fuel injection device, a driving unit structure has a magnetic aperture, in which an inner diameter is gradually enlarged toward the mover side, provided in an inner peripheral surface of the magnetic core. It is possible to reduce magnetic delay time upon valve opening from the supply of the electric current to the coil to the rise of magnetic flux and magnetic delay time upon valve closing from the stoppage of the electric current to the coil to reduction of magnetic flux, by providing a magnetic aperture in the inner peripheral surface of the magnetic core. Thus it is possible to improve the dynamic responsiveness upon valve opening and valve closing.

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： 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.
