燃料噴射弁。A cylindrical core with an outer end facing the outside of the case, a valve seat disposed on an extension of the inner end of the core, and a valve body floatingly supported between the valve seat and the core; a rod movably housed in the core in the axial direction; a spring stretched between the tip of the rod and the back surface of the valve body to urge the valve body toward the valve seat; an electromagnetic coil wound around the outer circumferential surface of the core near the inner end to attract the valve body in a direction that moves the valve body away from the valve seat against the spring;
In the fuel injection valve, the dynamic flow rate is adjusted and maintained at a predetermined value by changing the set pressure of the spring by adjusting the axial position of the rond, and the core is punched after adjusting the axial position of the rond. 1. A fuel injection valve for an internal combustion engine, characterized in that a rond is fixed to the outer end of the core, and a cover is fixed to the outer end of the core by caulking via a sealing member.
