摘要： PROBLEM TO BE SOLVED: To provide a fuel injection valve having large magnetic attraction force and high operation responsiveness of a movable member.
SOLUTION: Working gaps are formed between a first movable core 71 and a first fixed core 53, and between a second movable core 72 and a second fixed core 63 respectively. A current is applied to a first coil 52 to generate magnetic attraction force between the first movable core 71 and the first fixed core 53, and a current is applied to the second coil 62 to generate magnetic attraction force between the second movable core 72 and the second fixed core 63. A needle 44 is thereby driven by the magnetic attraction force generated by the first coil 52 and second coil 62. Further, since a plurality of working gaps are formed, magnetic flux generated at the first coil 52 and second coil 62 is efficiently converted into magnetic attraction force. The magnetic attraction force for driving the needle 44 can thereby be enhanced, and the driving responsiveness of the needle 44 can be enhanced.

摘要： PROBLEM TO BE SOLVED: To suppress an engine output even if a throttle valve is continuously driven to open, resulting in a failure that a full open position is reached.SOLUTION: A position of a full open stopper 7 for limiting the aperture of the throttle valve 3 at a full open position is located such that the throttle valve 3 has the aperture for again narrowing a flow path of an intake pipe 2 beyond the aperture for fully opening the intake pipe 2. Thus, even if the throttle valve 3 is continuously driven to open, resulting in a failure that the full open position is reached, the engine output can be suppressed since the full open position is set at the position where the throttle valve 3 has the aperture to narrow the flow path of the intake pipe 2.

摘要： PROBLEM TO BE SOLVED: To provide a fuel injection valve for promoting atomization of a fuel spray injected from a nozzle port.
SOLUTION: A flat disk-like combustion chamber 202 is formed between an inlet side end surface 24 of a nozzle port plate 20 and a tip surface 32 of a nozzle needle 30. The nozzle port 22 is formed on the inner peripheral side of a circular envelope 212 of crossing with the inlet side end surface 24 of the nozzle port plate 20 in a virtual surface 210 of extending an inner peripheral surface 14 of a valve body 12 to the fuel downstream side. An annular wall 26 projecting toward a nozzle needle 30 from the inlet side end surface 24 of the nozzle port plate 20, is formed in an inner peripheral side edge part of the four nozzle ports 22. The nozzle needle 30 separates from a valve seat 15, and among fuel flowed in a fuel chamber 202 from a fuel passage 200, the fuel passed to the inner peripheral side on an inlet of the nozzle ports 22 from the outer peripheral side, collides with the wall 26, and is forcibly changed in the flowing direction toward the nozzle ports 22.

摘要： PROBLEM TO BE SOLVED: To provide an inexpensive fuel injection valve capable of finely adjusting fuel injection quantity even if coil electrifying period is short without causing deterioration of magnetic characteristic.
SOLUTION: When electrifying a coil 32, a movable core 35 integrated with a needle 24 is moved at the predetermined distance, and brought in contact with a sliding pipe 60. When the movable core 35 is moved toward a fixed core 33 side, the movable core 35 is pushed to an injection hole 23 side by a first spring 41, and pushed by a second spring 42 when the movable core 35 is brought in contact with the sliding pipe 60. With this structure, the force to be applied to the movable core 35 is small in the initial time of the movement, and increased on the way of the movement. Quick movement of the needle 24 and the movable core 35 integrated with each other can be secured in the initial time of the movement, and moving speed of the movable core 35 is lowered before the movable core 35 collides with the fixed core 33. As a result, bound of the movable core 35 collided with the fixed core 33 is reduced.
