摘要： In an electromagnetic fuel injection valve designed so that the contact of a movable attraction face at a rear end of a movable core with a stationary attraction face included at a front end of a stationary core is inhibited, a ring-shaped stopper (28) made of a material non-magnetic or magnetic weakly more than a movable core (18) is press-fitted into an inner periphery of a rear portion of the movable core (18), and a flat abutment face (51), which is disposed at a location displaced from a flat movable attraction face (41) formed at the rear end of the movable core (18) toward a stationary attraction face (42), is formed at a rear end of the stopper (28) to be able to abut against the stationary attraction face. A slant (52) is formed on an inner periphery of the rear end of the movable core (18) and an outer periphery of the rear end of the stopper (28) to continuously and smoothly connect the movable attraction face (41) and the abutment face (51) to each other. Thus, the accumulation and deposition of chips and a magnetic powder can be prevented, and the area of application of an electromagnetic attraction force to the movable core can be increased substantially, while decreasing the number of parts and the number of assembling steps to provide a reduction in cost.

摘要： In an electromagnetic fuel injection valve in which a first resin-molded layer that is made of a synthetic resin, covers a solenoid section, and forms a coupler main portion that defines a framework of a power-receiving coupler is covered by a second resin-molded layer made of a synthetic resin that is different from that of the first resin-molded layer so that an outer face of the coupler main portion is exposed from a middle part up to the extremity of the coupler main portion, an endless engagement groove (45) is provided on the outer periphery of the middle part of the coupler main portion (40a) of the first resin-molded layer (41), the second resin-molded layer (42) engaging with the endless engagement groove (45), and an extending portion (42b) extending further outward than the engagement groove (45) is formed in the second resin-molded layer (42) so that the extending portion (42b) makes contact with an outer face of the coupler main portion (40a) when in a non-engaged state and covers the coupler main portion (40a). This prevents a gap or a bulge from occurring in a boundary section between the two resin-molded layers, thus improving the connectivity of a power-supplying coupler to a power-receiving coupler and the merchantability.
