摘要： PROBLEM TO BE SOLVED: To exhibit the accurate valve function over a long period, by sufficing durability, while securing airtightness/fluid-tightness of a valve function part, in a normally closed fuel injection valve. SOLUTION: This fuel injection valve 1A has a stopper core 3 being a fixed iron core, a valve system 10 having a valve member 15 on the tip side of a rod part 10a extended from an expanded part 10b being a movable iron core and a seat member 5, and closes the valve by energizing force of a valve closing spring 16. The rod part 10a has a sliding hole 10c on the tip side. The valve member 15 having a valve element 15a is slidably inserted in the axial direction, and energizes the base end side by a coil spring 17. The energizing force when closing the valve, is set weaker than the valve closing spring 16. The valve element 15a is brought into close contact with a valve seat 5b in a state of compressing the coil spring 17 by retreating by a predetermined width in the sliding hole 10c when closing the valve. The valve element 15a separates from the valve seat 5b by retreating by engaging with the rod part 10a side by a stopper 15d on the rear end side when opening the valve. COPYRIGHT: (C)2007,JPO&INPIT
