摘要： To enable the inclination of the injection direction and the distribution of the penetration force of spray to be adjusted over a wide range, and an axially symmetrical spray shape to be obtained even when the injection hole is inclined, or the shape of the spray to be changed without inclining the injection hole, a fuel passageway 203 is provided as a swirling force adjustment means between the valve seat 201 and injection hole 101 of the fuel injector. This swirling force adjustment means adjusts the distribution of the swirling force of the fuel flowing into injection hole 101, and thus adjusts the spray shape obtained as a result.

摘要： At an outlet portion of an injection hole (8) of a fuel injection valve (1), through removal of a part (A1, 7B) of a wall forming the injection hole (8), a restriction to a spray flow is eliminated, thereby, a deflection of the spray occurs in which the spray is rich at the side where this restriction is released and is lean at the side that is restricted. Thus, the ignition property of an internal combustion engine is improved, and an optimum spray is realized which reduces the amount of unburnt gas components being exhausted.

摘要： A valve structure which works easily, does not increase production cost, can reduce dispersion in a side gap by restricting eccentricity and incline of a valve body and can maintain highly accurate injection. An electromagnetic fuel injection valve is required which is easy to manufacture even in a narrow valve structure. A guide portion is provided having one end fixed to an injection valve main body for guiding the valve member. A nozzle guide body constituting a magnetic passage portion to surround a magnetic member connected and fixed to one end of the valve member by the same material is provided. Accordingly, it is possible to reduce dispersion of a side gap constituting the magnetic passage, and it is also possible to stabilize an axial motion of the valve member, whereby high injection accuracy is maintained and an inexpensive injection valve is obtained.
