摘要： A moving iron core that reciprocates in axial direction in response to a fuel injection signal is provided with a radial recess of a predetermined width and a predetermined depth on the outer circumference at a position facing a magnetic characteristic change portion produced in a yoke due to heat generated when a sleeve and the yoke are welded together. As a result, it is possible to suppress the variation in injection quantity characteristic of the products caused by the magnetic characteristic change portion of the yoke due to the heat generated at the time of welding the sleeve and the yoke together.

摘要： A fuel injection valve for reducing carbon deposit on a passage portion between a seat portion and an injection port. The fuel injection valve includes an injection port 13 for injecting a fuel that is arranged to face a combustion chamber of an internal combustion engine. A seat portion H, where a valve element 8 comes in contact with a face of a valve seat 11 to intermit fuel injection, is arranged at a place upstream the injection port 13. The valve element 8 is conical at a portion downstream the seat portion H to an inlet of the injection port 13. The sectional area of the passage between the valve element 8 and the face of the valve seat 11 at the time of fully opening the valve element 8 is arranged so that the sectional area of the passage downstream of the vicinity of the seat portion H is larger. A tapered face 17 having a bore not more than 1/2.5 of an inner diameter of a swirl chamber 16 of a swirler 10 is formed on the face of the valve seat 11 which is downstream the seat portion H.
