摘要： A fuel injection valve is provided that includes a valve seat member (3) having a conical valve seat (8) and a valve hole (7) formed through a central part of the valve seat (8), a valve body (18) working in cooperation with the valve seat (8), and an injector plate (10) joined to the valve seat member (3) and having a plurality of fuel injection holes (11) radially outwardly displaced from the valve hole (7), a diffusion chamber (39) providing communication between the valve hole (7) and the fuel injection holes (11) being provided between the valve seat member (3) and the injector plate (10), wherein the diffusion chamber (39) formed between the valve seat member (3) and the injector plate (10) is in an annular shape, has a diameter that is larger than that of the valve hole (7), and has inner ends of the fuel injection holes (11) opening therein, and a plurality of fuel passages (42a, 42b) are disposed within the valve hole (7), the plurality of fuel passages (42a, 42b) reversing within the valve hole (7) fuel that has passed through the valve seat (8) and guiding the fuel to the diffusion chamber (39). This enables atomization of injected fuel to be promoted and penetrability to be improved for the fuel injection valve.

摘要： In a fuel injection valve, a fuel guide member facing the valve hole is connected to an injector plate, and an annular diffusion chamber is formed between a valve seat member and the injector plate. A pair of first notches, a pair of second notches, and a plurality of closing parts are formed in an outer periphery of the fuel guide member. The first notches are arranged on a first diameter line of the valve hole. The second notches are arranged on a second diameter line perpendicular to the first diameter line. The closing parts are provided between the first and second notches to partially close the valve hole. A plurality of fuel injection holes are dispersally arranged in outside regions corresponding to the closing parts and inside regions corresponding to the first notches. A first tip end corner of the closing part adjacent to the first notch is formed into an edge shape or a minute arc shape, while a second tip end corner of the closing part adjacent to the second notch is formed into a large arc shape. Thus, it is possible to reduce a particle size of injected fuel and improve penetrability.
