Title:

ELECTROMAGNETIC FUEL INJECTION VALVE

Document Type and Number:

WIPO Patent Application WO/2014/196240

Kind Code:

A1

Abstract:

This electromagnetic fuel injection valve is configured such that a core (101), which is one of the parts constituting the electromagnetic fuel injection valve, is joined to a metal joint (2) by welding, and such that the amount of melting of the metal-joint-side portion of the weld where the metal joint (2) and the core (101) are welded is set to be greater than the amount of melting of the core-side portion of the weld. The electromagnetic fuel injection valve is provided with: a metal-joint end surface (203); a fuel seal section that has a cross-sectional area smaller than the area of the metal-joint end surface (203); and a core end surface (105) that has an area greater than the cross-sectional area of the fuel seal section. The metal-joint end surface (203) and the core end surface (105) are configured so as to communicate with each other through the fuel seal section.
