Abstract:
1. A fuel injection valve comprising: a valve member that defines a jet nozzle through which fuel is intermittently injected; a moving core that reciprocates with the valve member; a fixed core that is mounted on an opposite side of the jet nozzle with respect to the moving core, the fixed core facing to the moving core to generate force of magnetic attraction between the fixed core and the moving core; a pipe member that covers both an outer periphery of the moving core and an outer periphery of the fixed core, the pipe member including a magnetic pipe and a non-magnetic pipe, the non-magnetic pipe located on one of both sides of the magnetic pipe in an axial direction of the magnetic pipe, the non-magnetic pipe joined to the magnetic pipe; a coil that is mounted on an outer periphery of the pipe member to generate force of magnetic attraction between the moving core and the fixed core by energizing; and a yoke that covers an outer periphery of the coil, wherein the yoke defines a first axial end that is connected to the non-magnetic pipe, and the yoke defines a second axial end that is connected to the magnetic pipe.
