摘要： PROBLEM TO BE SOLVED: To improve reliability of an injector by stopping a needle without making the needle collide on a stopper at time of maximum lift of the needle. SOLUTION: A fuel introduction passage 11 introducing high pressure fuel to a nozzle chamber 3 is obliquely provided on a needle sliding shaft part 8, and a lower side opening end of the fluid introduction passage 11 includes a sliding part opening end opening at an outer circumference surface of the needle sliding shaft part 8. The sliding part opening end is blocked by overlapping with a nozzle sliding hole 5 when a needle 10 rises. In the injector, the fuel introduction passage 11 is restricted extremely before reaching allowable lift of the needle 10 thereby. Consequently, "valve closing force by pressure in a pressure control chamber 1 and a spring 28" and "valve opening force by pressure in a nozzle chamber 3" balance when the needle 10 rises, rise of the needle 10 is stopped, and reliability is increased without causing collision at the maximum lift.

摘要翻译：要解决的问题：通过在针的最大升程时使针停止而不使针碰到止动件来提高注射器的可靠性。解决方案：将引导高压燃料的燃料引入通道11倾斜地设置在针滑动轴部8上，并且流体导入通道11的下侧开口端包括滑动部开口端针滑动轴部8的外周面。当针10上升时，滑动部开口端与喷嘴滑动孔5重叠而被阻挡。在喷射器中，在达到针10的允许升程之前极限制燃料引入通道11。因此，当针10上升时，“针10的上升停止，”压力控制室1和弹簧28中的压力的关闭力“和”喷嘴室3内的压力的开阀力“ 增加而不会在最大升程时造成碰撞。版权所有（C）2011，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To improve a margin with respect to high-pressure sealing property between a nozzle body and a valve body by reducing frictional force in fastening a retaining nut to reduce variation in fastening torque.
SOLUTION: A plurality of spherical bodies 18 is interposed and fastened between the axial force receiving surface 48A of the nozzle body 48 and the axial force applying surface 25A of the retaining nut 25 which axially screws and tightens the nozzle body 48 and valve body 20. Thereby, the frictional force in fastening the retaining nut 25 is reduced, and the sufficient axial force is generated with a small fastening torque. A torsional moment acting on the nozzle body 48 is also reduced by frictional force reduction, and eccentric wear with deformation of a high precision sliding part structure such as a needle is suppressed. Further, since variation in frictional force is reduced, variation in fastening torque is reduced, and the margin with respect to the high-pressure sealing property between the nozzle body 48 and the valve body 20 is improved.

摘要： PROBLEM TO BE SOLVED: To determine the lift of a needle with high accuracy by using an electromagnetic actuator, in a fuel injection device whose lift of a needle is determined by means of a permanent magnet provided in the needle.SOLUTION: When an (actual output (solid line B)) is obtained by generating a (command value (solid line A)), an ECU subtracts an (influence output (solid line C)) from the(actual output (solid line B)) so as to determine an (operation waveform (solid line D)), and to determine an (integration waveform (solid line β)) similar to the(lift of needle) by integrating the (operation waveform (solid line D)). Since the lift of needle is determined from the (actual output (solid line B)) while taking account of the (influence output (solid line C)), influence of an electromagnetic actuator can be eliminated, and the lift of needle can be determined with high accuracy.

摘要： PROBLEM TO BE SOLVED: To improve the valve opening responsiveness and valve closing responsiveness of a nozzle needle 9. SOLUTION: Since the nozzle needle 9 includes a valve guide (the periphery of an axial projecting portion 16) reciprocatingly slidably guiding the valve 14 of an intermediate valve 14, the valve 14 of the intermediate valve is moved without being inclined to a specified valve moving direction. Accordingly, it is possible to surely close/open a fuel introducing flow passage (a fuel flow passage 31, an in-orifice 32, and an annular recessed groove 33). Also, it is possible to enlarge a gap 35 formed between the valve 14 of the intermediate valve and the valve storage recessed portion 57 of a cylinder 22. Herewith, since fuel pressure in a control chamber 12 is rapidly dropped, it is possible to improve the valve opening responsiveness of the nozzle needle 9. Also, since the fuel pressure in the control chamber 12 is rapidly increased, it is possible to improve the valve closing responsiveness of the nozzle needle 9. COPYRIGHT: (C)2011,JPO&INPIT
