摘要： A solenoid actuator with a double action for a fuel injector comprising an armature (39), a first electromagnetic coil (33), a second electromagnetic coil (29) and a permanent magnet (27). When the first electromagnetic coil (33) is energised in use an electromagnetic field is produced which acts to move the armature (39) in a first direction. When the second electromagnetic coil (29) is energised in use the electromagnetic field produced is opposite to the magnetic field of the permanent magnet thereby cancelling out that field which acts to move the armature in a second direction.

摘要： A fuel injection device 1 A includes a nozzle body 10 equipped with multiple injection apertures 12, a needle valve 20 arranged in the nozzle body, a fuel swirl portion 24 in which fuel FE is swirled along an inner wall surface of the nozzle body, and a guide portion 22 applying swirl force to the fuel and then guiding the fuel to the fuel swirl portion, the fuel swirl portion being arranged at a position at which the fuel swirl portion partially overlaps with the injection apertures. When the needle valve is at a low lift position, the fuel swirl portion overlaps with parts of the injection apertures so that the shape of sprayed fuel can be formed in diffusive spray having a wide spray angle. When the needle valve is at a high lift position, the shape of sprayed fuel can be formed in column-shaped spray having a narrow spray angle.
