    • PROBLEM TO BE SOLVED: To provide a fuel injection nozzle and an injector using it for promoting atomization of spray while holding strength of a nozzle hole plate. SOLUTION: A nozzle hole 31 is formed to a nozzle hole plate 30 attached to a tip of a nozzle body. An indentation part 32 is formed to the nozzle hole plate 30 on a peripheral edge 31a of an inlet side opening of the nozzle hole 31. Therefore, thickness of the nozzle hole plate 30 near the nozzle hole 31 is reduced, so as to shorten the overall length of the nozzle hole 31. Because the fuel flows into the nozzle hole 31 along the recessed part 32, a position collided with the fuel approaches to the outlet side of the nozzle hole 31. The fuel generating turbulence on the outer side of the nozzle hole 31 is difficult to be straightened by the shortened nozzle hole 31. Accordingly, atomization of spray of the fuel is promoted. On the other hand, at a portion other than the recessed part 32, thickness of the nozzle hole plate 30 is maintained. Therefore, strength of the nozzle hole plate 30 is maintained.

    • 要解决的问题:提供一种燃料喷射喷嘴和使用它的喷射器,用于在保持喷嘴孔板的强度的同时促进喷雾雾化。 解决方案:喷嘴孔31形成在喷嘴孔板30上,喷嘴孔板30安装在喷嘴体的顶端。 在喷嘴孔31的入口侧开口的周缘31a上,向喷嘴孔板30形成有压痕部32,因此,喷嘴孔31附近的喷嘴孔板30的厚度缩小, 由于燃料沿着凹部32流入喷嘴孔31,所以与燃料相撞的位置靠近喷嘴孔31的出口侧。燃料的产生紊流在喷嘴孔31的外侧。 喷嘴孔31难以被缩短的喷嘴孔31矫直。因此,促进燃料喷雾雾化。 另一方面,在凹部32以外的部分,保持喷嘴孔板30的厚度。 因此,保持喷嘴孔板30的强度。 版权所有(C)2004,JPO

    • PROBLEM TO BE SOLVED: To provide a fuel injection valve allowing a fuel injection rate to be changed with simple structure.SOLUTION: A needle 40 formed of a magnetic material includes a body 41, a seal part 42, and a needle large-diameter part 44. When the seal part 42 abuts on a valve seat 312, a distance d1 is formed between an end face 61 of a fixed core 60 and a second stepped face 49 of the needle large-diameter part 44, and a distance d2 smaller than the distance d1 is formed between the end face 61 and an end face 57 of an annular projected part 56 of a movable core 50. When power supply is started on a coil 70, the movable core 50 and the needle 40 are attracted to the fixed core 60, the end face 57 abuts on the end face 61 first, and the needle 40 is lifted by the distance d2. When more current flows in the coil 70, the second stepped face 49 abuts on the end face 61, and the needle 40 is lifted by the distance d1. An fuel injection rate is controlled thereby in a fuel injection valve 1.

    • PROBLEM TO BE SOLVED: To provide a fuel injection device capable of appropriately controlling an injection rate.SOLUTION: An annular second energizing means 90 is fixed to an end face on the side of a valve seat 20 of a movable core 60. When a coil 40 is energized and the movable core 60 is magnetically attracted to a fixed core 50, a needle valve 30 is locked to the second energizing means 90, and moved in a valve opening direction together with the movable core 60. After the needle valve 30 is abutted on a stopper 80, the movable core 60 is further moved to the side of the fixed core 50. Thus, energizing force for energizing the movable core 60 in a valve closing direction is stored in a spring 70 and the second energizing means 90. When energization to the coil 40 is stopped, by the energizing force of the spring 70 and the second energizing means 90, the movable core 60 is moved in the valve closing direction and collides with the needle valve 30. Thus, the valve closing speed of the needle valve 30 is accelerated.
    • 要解决的问题:提供能够适当地控制喷射率的燃料喷射装置。 解决方案:环形第二激励装置90固定到可动芯60的阀座20侧的端面。当线圈40通电并且可动芯60被磁力吸引到固定芯50 针阀30被锁定到第二施力装置90,并与可动芯体60一起沿阀打开方向移动。在针阀30抵靠在止动件80上之后,可动芯体60进一步移动到侧面 因此,用于使可动铁芯60沿关闭方向通电的通电力被存储在弹簧70和第二激励装置90中。当向线圈40通电停止时,通过弹簧的激励力 70和第二通电装置90,可动铁心60在关闭方向上移动并与针阀30碰撞。因此,针阀30的关闭速度加快。 版权所有(C)2012,JPO&INPIT
