    Abstract: PROBLEM TO BE SOLVED: An object of the present invention is to sufficiently spread the spray generated by injection of fuel from a nozzle hole, ensures further minute fuel microparticles in spraying, and ensures the further homogeneous fuel microparticles in spraying.
    SOLUTION: The fuel flowed from the guide channels 18, 20 into the swirl chamber 13 is guided to the nozzle hole 6 while swirling in the swirl chamber 13 in the identical direction. The nozzle hole 6 is divided into a portion near a fuel-inflow end 51 and a portion near a fuel-outflow end 52. The portion near the fuel-outflow end 52 of the nozzle holes 6 is formed so as to have a flow passage cross-sectional area gradually increasing towards a fuel outflow-side opening end 6b, and includes a curved surface 54 formed by smoothly connecting an inner surface of the nozzle holes 6 at upstream end side in a fuel flow direction to an inner surface of the nozzle holes 6 at the portion near the fuel-inflow end 51 so as to smoothly and gradually increase the flow passage cross-sectional area. The curved surface 54 is configured to ensure further thin film-like flow by expanding a flow of the fuel in the nozzle holes 6 by means of Coanda effect.

    Abstract: An object of the present invention is to provide a fuel injection valve configured to suppress bouncing of a valve element that is caused as a result of the valve element being rendered elastic when the valve element collides with a valve seat.
    The fuel injection valve of the present invention includes the valve element configured to come into contact with the valve seat for closing an injection hole and to separate from the valve seat for unclosing the injection hole, an elastic member urging the valve element toward the valve seat, a movable iron core disposed to be in and out of contact with the valve element, a fixed iron core disposed to be opposed to the movable iron core, and a coil configured to generate electromagnetic force for moving the movable iron core. At least one lower rigidity part having reduced rigidity per axial unit length is provided between a surface where urging force of the elastic member is transmitted to the valve element and a seat part whereat the valve element comes into contact with and separates from the valve seat.

    Abstract: The disclosure relates to a fuel injection valve. The fuel injection valve for an internal combustion engine includes a needle which moves within a valve housing; a valve seat formed therein with an opening and closing hole which is opened and closed by the needle; an orifice plate which is attached to a lower portion of the valve seat and from which a fuel is injected through an injection hole; a fuel tube being a path through which the fuel injected from the orifice plate is supplied to the internal combustion engine; and a tube adaptor which is installed between the orifice plate and the fuel tube in order to prevent a leakage of the fuel supplied from the orifice plate to the fuel tube.

    Abstract: A liquid injector atomizer for direct injection in to the cylinder of an internal combustion engine is provided, with a supply of pressurized liquid a supply of pressurized gas, a body, and a nozzle with two or more orifices each for the liquid and the gas. Each orifice directs a jet of metered pressurized liquid or gas out of the injector body. At least two of the liquid jets are aimed at one or more collision points, where at least two gas jet streams collide at a same collision point or another collision point, thereby creating a finely atomized liquid.
