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.

摘要： A microcomputer calculates a fuel injection time. When the fuel injection time is longer than a predetermined specified time, the microcomputer sets a voltage level of a short-term injection signal to high and sets a peak current for coils in fuel injectors to a first peak current. When the fuel injection time is shorter than or equal to the predetermined specified time, the microcomputer sets a voltage level of the short-term injection signal to low and sets a peak current for the coils to a second peak current smaller than the first peak current.

摘要： A fuel injection valve includes a valve member, a first stop member, a second stop member, a movable core, a fixed core, and a coil. The valve member opens and closes an injection nozzle. The first stop member protrudes radially outward from said valve member. The second stop member protrudes radially outward from said valve member. The movable core is sandwiched between said first and second stop members. The movable core and one of said first and second stop members defines a fuel chamber. The fixed core is axially displaced from said movable core. The coil causes reciprocal axial displacement of said valve member such that said movable core axially reciprocates toward and away from said fixed core therewith.

摘要： In a fluid injection valve, a valve needle and a moving core are installed in the valve housing to be slidable in an axial direction. The moving core has a through hole in which the valve needle is slidably inserted. A stopper provided on the valve needle moves the valve needle integrally with the moving core when the moving core travels toward the fixed core with respect to the needle valve. An elastic member biases the valve needle away from the fixed core, and a helical spring biases the moving core toward the fixed core. A spring seat supports one axial end of the helical spring in both of the axial direction and a radial direction of the helical spring.

摘要： In a fuel injection valve, a valve member is reciprocable in a longitudinal direction of the valve member to open and close an injection hole. The movable core is reciprocable together with the valve member. The fixed core faces an opposite side of the movable core opposite from the injection hole. The spring applies a force to the valve member in one of reciprocable directions of the valve member. The coil generates a magnetic force to the fixed core when energized such that the fixed core attracts the movable core against the force. The force adjusting member is inserted into the fixed core with a clearance therebetween, wherein the force adjusting member is engaged with the spring. The support member is disposed on an opposite side of the fixed core opposite from the movable core, wherein the force adjusting member is press fitted in the support member.
