WIPO Patent Application WO/2017/064986
Kind Code:
A1
Abstract:
Provided is a fuel injection device with which the reliability of sealing by means of a valve body and a seat part can be improved, and the manufacturing cost can be reduced. This fuel injection device is equipped with a valve body 41 that forms a seal by making contact with an orifice cup 7 (seat member), a movable element 40 joined to and integrally formed with the valve body 41, and a movable core 4 that drives the movable element 40. The movable element 40, the valve body 41, and the movable core 4 are configured such that the hardness of the movable element 40 is closer to the hardness of the movable core 4 than that of the valve body 41 and the orifice cup 7.
