Fuel injection valve having internal pipe |
摘要 |
A pipe member of a fuel injection valve includes a magnetic pipe and a non-magnetic pipe in this order from the side of a jet nozzle plate. The non-magnetic pipe extends to the end of the fuel injection valve 10 opposed to the jet nozzle plate, and the non-magnetic pipe is formed with a fuel inlet. The non-magnetic pipe has the thickness of not less than 0.2 mm but not more than 1.0 mm. An end of the non-magnetic pipe on the side of the magnetic pipe is positioned on the side of a moving core relative to a facing portion of a fixed core that faces to the moving core, and on the side of the fixed core relative to a second end of a yoke connected to the magnetic pipe. The non-magnetic pipe covers the outer periphery of a gap defined between the moving core and the fixed core.
