摘要： In a fuel injection valve, it is intended to enhance valve-closing responsivity while maintaining durability (anti wear property) of a collision portion between a stationary core and a movable core and valve-opening responsivity.
An annular end face 106A of the movable core 106 in the fuel injection valve is provided with a collision portion 106C that collides to a stationary core 107 when the movable core is magnetically attracted toward the stationary core side and a non-collision portion that keeps a fluid gap between both cores at an area of an outer side or an inner side from the collision portion. The annular end faces of the stationary core and the movable core are coated with platings 30, 31 having anti wear property, and at least one of the platings of the stationary core and the movable core is formed in such a manner that the thickness thereof at the collision portion 106C is to be thicker and the thickness thereof at the non-collision portion is to be thinner.

摘要： A fuel injector and a fuel injection device are provided that, in order to achieve both low fuel consumption and high power output, can vary a spray shape in an outswinging fuel injector so as to form a spray suitable for each of stratified combustion and homogeneous combustion.
A nozzle 2 has a plurality of fuel paths 5 thereinside. A valve element 10 is vertically movable inside the nozzle 2, and has a conical valve element surface 16 that faces a conical valve seat surface 15 of the nozzle 2. The valve element surface abuts against the valve seat surface to form a seat portion 11 that seals fuel. The fuel paths 5 each have an opening portion upstream of the seat portion 11. A distance between the seat portion and the valve element when the valve element leaves the valve seat surface is variable. The fuel path has a cross-sectional area that can be larger or smaller than that of an annular gap between the seat portion and the valve element surface of the valve element.
