摘要： PROBLEM TO BE SOLVED: To provide a fuel injection valve with reliability constituting a nozzle body 48 with excellent durability in which excessive stress is hardly generated under a high pressure fuel.
SOLUTION: Electrolytic processing of a suitable electrode shape and post-processing by a boring tool of a predetermined shape are performed on inner walls of a needle hole 45 of the nozzle body 48 and a bag hole part 45C connected/crossed to an inclined high pressure fuel passage 46 in order to make the crossing angle to an obtuse angle of 90° or more. Alternatively, a center of the bag hole part 45C is preferably made eccentric to the high pressure fuel passage 46 side or it is preferably crossed to the maximum diameter part of the bag hole part 45C. Thereby, the obtuse angle of the crossing angle is effectively retained, generation of excessive stress of the bag hole part 45C inner wall is suppressed and breaking of the nozzle body by crack is prevented.

摘要： PROBLEM TO BE SOLVED: To provide an electromagnetic actuator and a fuel injection valve excellent in suction force and responsibility by making an armature and a stator core equal to each other in magnetic property.
SOLUTION: A moving member core 34 is formed of sintered metal composed of 1LSS to 3LSS to enhance the magnetic property of the moving member core 34. At the same time, a shaft 35 is made of a ferromagnetic material to enhance the magnetic property of the armature 24. The resin powder content of the stator core 32 is set to 0.005 to 0.1% by mass to increase the magnetic flux density. The resin grain size is set to 50 μm or less, preferably 25 μm or less, and thereby the core loss is reduced and the magnetic property of the stator core 32 is also enhanced. Thus, the direct-current magnetic property of the stator core 32 is made substantial equal to that of the armature 24. As a result, a fuel injection valve excellent both in the magnetic property of the armature 24 and in that of the stator core 32 and excellent in suction force and responsibility is obtained.

摘要： PROBLEM TO BE SOLVED: To provide a flow control member and a fuel injection device using it capable of reducing damage to the inner wall when the throttled flow of an orifice is adjusted and also a dispersion in the flow control characteristics caused by any damage to the inner wall.
SOLUTION: A first orifice 51 to throttle the passage section area of a first passage 41 is located apart from the connection part 44 between the first passage 41 and the second passage 42. In the case therefore, a polishing fluid is fed from the end 41a to the second passage 42 via the first orifice 51, the pressure of the polishing fluid with the flowing speed raised by the first orifice 51 lowers before the fluid reaches the second passage 42. A diametrically enlarged part 45 is formed from the first orifice 51 to the connection part 44, so that the flowing speed of the fluid lowers. This reduces the energy which the inner wall 40a receives from the polishing fluid. Accordingly it is possible to reduce damage to the inner wall 40a and a dispersion in the flow control characteristics caused thereby.

摘要： PROBLEM TO BE SOLVED: To provide a pipe joint wherein sealing performance is higher as fluid pressure is higher, although a conventional pipe joint to be used for a high pressure fuel pipe adopts a structure of pushing a tapered face for sealing, where fuel pressure, when higher to expand a first pipe to the outside, operates in the direction of separating the first pipe away from a second pipe to easily cause seal leakage. SOLUTION: The pipe joint on which high pressure fuel operates in a common rail fuel injection device adopts a structure of putting the first pipe 21 inside the second pipe 22 to push the outer peripheral face of the first pipe 21 against the inner peripheral face of the second pipe 22 with the fuel pressure in the first pipe 21. Thus, in the state that the high pressure fuel operates on the internal of the first pipe 21, the high pressure fuel expands the first pipe 21 to the outside to make seal bearing pressure between the outer peripheral face of an abutting portion 24 and the inner peripheral face of the second pipe 22 further higher than in press-in. Namely, sealing performance is higher as higher pressure operates, and so there is no fuel leakage when the high pressure fuel is supplied. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To improve responsivity to actuation of an injector in a drive unit for actuating a solenoid of the injector by supplying power through a battery and a capacitor.
SOLUTION: The driving device includes switches Sb, Sc for changing over from a first state to a second state, and vice versa. In the first state, a terminal CT1 on the negative side of the capacitor C is connected to a terminal BT1 on the positive side of a battery B. In the second state, the terminal CT1 is connected to a terminal BT2 on the negative side of the battery B. In actuation of an injector Ai, the first state is selected to increase the applied voltage to the solenoid Li by the voltage of the battery B to sharpen the rise of the current flowing in the solenoid Li so as to increase the responsivity of the injector Ai. In an operation stop of the injector Ai, the power supply to the solenoid Li is stopped to enter the second state, and buildup of energy in the solenoid Li is recovered into the capacitor C.

摘要： PROBLEM TO BE SOLVED: To effectively apply high seal bearing pressure to a metal seal surface of a fuel injection valve especially near the outer periphery of a high pressure fuel hole 46A and secure positive sealability of high pressure fuel.
SOLUTION: A tip end surface of a valve body and a back end surface of an injection nozzle are fastened into pressure contact with each other by a retaining nut, and are sealed by a metal seal. In order to increase surface pressure of the seal surface by fastening axial force, a recess 6 is provided on the outer periphery of the high pressure fuel hole 46A communicating with a seal surface outer edge part, so that the central part and its vicinity of the high pressure fuel hole 46A is secured as a seal surface instead of the recesses 6 being conventionally provided around the central shaft of the nozzle, or a holding seal surface is made by providing a contact surface on the outer edge part of the recess 6 separate from the seal surface near the high pressure fuel hole 46, enhancing deformation resistance. Positive sealability of high pressure fuel is secured especially by highly maintaining the seal bearing pressure on the peripheral part of the high pressure fuel hole 46A.

摘要： PROBLEM TO BE SOLVED: To provide a spring member with a wide load range and a hardly wearing abutting part by modifying a spring member shape applying an initial load to a piezo element in a piezo driving device used in a piezo type injector.
SOLUTION: The spring member 31 comprises an annular plate spring, and since a radial cross sectional shape of a plate face is substantially V-shaped, spring force is larger than a disc spring which can be installed in the same space. In the piezo driving device of the piezo type injector, wear can be prevented since there is no relative displacement between abutting parts of a V-shaped middle part 313 of the spring member 31, and a first piston and a plate member when a preset spring of combining two spring members 31 is arranged between the first piston displaced integrally with a piezo stack, and the plate member arranged in a lower end of a vertical hole.
