Japanese Patent JP7376337
Kind Code:
B2
Abstract:
To suppress the generation of a flow of a magnetic flux that prevents the movement of each moving core, in a fuel injection valve having two moving cores.SOLUTION: A fuel injection valve 100 is equipped with a housing 20 having a longitudinal direction Z, a fixed core 60, a first moving core 150 and a second moving core 250 capable of moving in the longitudinal direction, a needle 40, and a coil 70. The first moving core has a first magnetic portion 151 configured by a soft magnetic material, and a first opposing portion 160 opposing to the second moving core in the longitudinal direction. The second moving core has a second magnetic portion 251 configured by a soft magnetic material, and a second opposing portion 260 opposing to the first moving core in the longitudinal direction. At least a part of the first opposing portion and the second opposing portion is configured by a material that has magnetic permeability lower than that of the first magnetic portion, and has a magnetic permeability lower than that of the second magnetic portion.SELECTED DRAWING: Figure 1
