摘要： In an electromagnetic fuel injector of an internal combustion engine, an electromagnetic coil for valve driving is to be wound on a bobbin, and the bobbin is constituted by a synthetic resin containing a filler having good heat conductivity. For example, the bobbin with the coil to be wound thereon is constituted by PPS containing iron oxide and/or alumina as a filler. Two types of electromagnetic coils different in characteristics are provided in the fuel injector. These coils are wound separately on one bobbin in an axial direction. Among them, one coil (hereinafter referred to as “first coil”) has a winding region near a movable unit with a valve element being the object of magnetic suction, and other-coil (hereinafter referred to as “second coil”) has a winding region away from the movable unit. The bobbin has a step difference of the outer diameter so that the bobbin outer diameter in the region with the second coil to be wound thereon is smaller than the bobbin outer diameter in the region with the first coil to be wound thereon, and the bobbin inner diameter has a step difference in that the bobbin inner diameter in the region with the first coil to be wound thereon is made large partially so as to secure an annular space to interpose a seal ring therein.

摘要： An electromagnetic drive device has yokes that are magnetically connected with each other and cover an outer periphery of a coil. The coil is wound around a spool. Terminals are guided by a guiding portion of the spool and are fit to the spool. Ends of the coil are electrically connected with ends of the terminals. Protrusions are formed on both circumferential side faces of the spool. The ends of the terminals are bent toward the circumferential ends of the yoke until the ends are locked by tapered faces formed on the protrusions. Accordingly, work for bending electric connections between the coil and the terminals is facilitated, and an insulation failure between the terminals or the coil and the yoke can be prevented.

摘要： A fuel injection valve comprises a body, a valve member, a coil, a movable core, a fixed core, and a housing member. The body has a nozzle hole. The valve member allows injection of fuel from the nozzle hole. The coil generates a magnetic field. The movable core axially reciprocates with the valve member. The fixed core is provided adjacent to a side of the movable core that is opposite the nozzle hole. The fixed core attracts the movable core and moves with the valve member due to the magnetic field generated from the coil. The housing member has a first axial end fixed to the body. The housing member covers the coil and forms a magnetic circuit together with the body, the movable core, and the fixed core due to the magnetic field generated by the coil.
