摘要： A fuel injection device has a nozzle body formed with an injection hole for injecting fuel and a nozzle needle reciprocating in the nozzle body to open and to close the injection hole. The nozzle needle has a sliding portion capable of moving in the nozzle body in a sliding manner, an insertion portion, of which diameter is smaller than that of the sliding portion, and a pressure receiving portion connecting the sliding portion with the insertion portion. The nozzle body has a guide portion for slidably holding the sliding portion and a fuel sump chamber formed on the injection hole side of the guide portion. The insertion portion is inserted through the fuel sump chamber. A clearance decreasing toward the fuel sump chamber is provided between the guide portion and the sliding portion.

摘要： A tip end surface of a valve body and a back end surface of an injection nozzle contact each other with pressure by being fastened using a retaining nut and thereby form a metal seal structure to achieve a metal seal. To increase a surface pressure in a seal surface by fastening axial force, conventional recesses around the central axis of a nozzle are replaced so that proximity of a high pressure fuel hole is secured as a seal surface. An outside recess is provided outside of the proximity of the high pressure fuel hole to link with an outer peripheral border of the metal seal structure. Alternatively, a contact surface functioning as a retaining seal surface is added outside of the outside recess to be apart from the proximity of the high pressure fuel hole.

摘要： A fuel injection valve includes a solenoid, which is filled with low-pressure oil. The solenoid receives a biasing means and a movable member. The movable member is actuated by the biasing means and magnetic force generated by the solenoid. The movable member includes a flat-plate portion that contacts with the solenoid and departs from the solenoid. The outer circumferential periphery of the flat-plate portion has multiple notches, through which low-pressure fuel flows into to the upper side of the flat-plate portion that has an oil passage groove, through which a center portion of flat-plate portion communicates with the outer circumferential portion of flat-plate portion. Each notch has a deepest portion that is radially most recessed from the outer circumferential periphery of the flat-plate portion. The oil passage groove is apart from a deepest portion of the notches.

摘要： A catalytic converter has a ceramic catalytic support, a cylindrical casing for holding the catalytic support therein and a holding member disposed between the catalytic support and the casing. The holding member has a plurality of net-like layers, each of which is parallel to a circumferential surface of the catalytic support and has fibers randomly tangled with each other. Because of this structure, when the catalytic converter is assembled, damage to the fibers and separation of the fibers of the holding member can be prevented. As a result, the holding member can securely and steadily hold the catalytic support within the casing.

摘要： On an inner wall of a bag-shaped hole portion of a nozzle body, a cross angle between the bag-shaped hole portion and a needle hole or an oblique high-pressure fuel passage of the nozzle body is made obtuse, i.e. at 90 degrees or larger, through an electrochemical machining process with a suitably-shaped electrode or through after-processing with a boring tool having a predetermined shape. The center of the bag-shaped hole portion may be deviated toward the high-pressure fuel passage or the high-pressure fuel passage may be connected to a maximum diameter portion of the bag-shaped hole portion to provide the obtuse cross angle. Thus, excessive stress on the inner wall of the bag-shaped hole portion or a breakage of the nozzle body due to a crack can be inhibited.

摘要： A magnetism property of an armature is increased by including a moving core of sintered metal of 1LSS to 3LSS, and a shaft of a ferromagnetic material. By contrast, a stator core contains 0.005 to 0.1 weight % resin powder, whose particle diameter is set to 50 μm or less, in particular, 25 μm or less, so as to decrease a core loss and increase a magnetism property. The stator core thereby becomes approximately equivalent to the armature in a direct current magnetism property, so that an electromagnetic actuator and a fuel injection valve that are excel in suction force and response are provided.
