Document Type and Number:
Japanese Patent JP2023000621
Kind Code:
A
Abstract:
To stabilize the behavior of a movable element by suppressing increase in the mass of the movable element, while improving foreign substance capturing performance by arranging a fuel filter inside the movable element.SOLUTION: A fuel injection valve 1 includes: a valve body 27c; a movable element 27 which has a movable iron core 27a and a rod part 27b, and in which a fuel passage is formed so as to be communicated with the inner peripheral side of the rod part 27b from the inner peripheral side of the movable iron core 27a; a fixed iron core 25 for generating a magnetic attraction force between itself and the movable iron core 27a opposing to the movable iron core 27a; and an energization member 39 for energizing the movable element 27. The movable element 27 includes: a communication hole 27bo for communicating the inner peripheral side and the outer peripheral side of the rod part 27b; a hole 27ba for forming the fuel passage in the rod part 27b; and a fuel filter 80 stored inside the hole 27ba. The fuel filter 80 is arranged in a relatively displaceable manner with respect to the movable element 27.SELECTED DRAWING: Figure 3
