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.

摘要： In an injector used for an internal combustion engine, a favorable magnetic attraction force is obtained to reduce a controllable minimum injection amount of a fuel injection amount. In a fuel injection valve in which a fixed core and a moving element is contained inside a pipe-shaped member, and a coil and a yoke are provided on an outer side thereof, a space for placing the coil is placed so that an inner circumference length in a vertical section of the space becomes smaller than an outside diameter of the yoke, or a height of the space in an axial direction of the fixed core becomes smaller than a diameter of the fixed core.

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： The drive device is configured to, during a time interval between an earlier fuel injection (first fuel injection) and a later fuel injection (second fuel injection), supply an electromagnetic coil with an intermediate current at a voltage with a level of not opening the valve. Further, the drive device sets a voltage application for supplying the intermediate current to initiate before a valve closing in the earlier fuel injection and terminate before half a period of time between a first instant when the valve is closed in the earlier fuel injection and a second instant when a supply of a drive current for opening the valve is initiated in the later fuel injection.

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.
