Electromagnetic Fuel Injection Valve

摘要

In an electromagnetic fuel injection valve including a resin molded part of a synthetic resin which integrally has a coupler to which a connecting terminal connecting to a coil of a coil assembly is faced, and in which at least part of the solenoid housing is embedded, the resin molded part ( 7 ) is formed by a first resin molded layer ( 7 a) which is formed of a synthetic resin with mixture of glass fibers to cover at least part of the solenoid housing ( 25 ) and form at least part of a coupler ( 40 ), and a second resin molded layer ( 7 b) which is formed of thermoplastic polyester elastomer with mixture of glass fibers excluded to cover the first resin molded layer ( 7 a). This makes it possible to effectively suppress occurrence of operation sound while securing sufficient strength for obtaining reliability of an electrical connecting portion and to make the fuel injection valve compact.
