摘要： PROBLEM TO BE SOLVED: To reduce load required for relative movement of an outer diameter correction tool at a time of outer diameter correction and to secure a sufficient moving margin of a combustion gas seal for an injector. SOLUTION: The resin combustion gas seal 22 to which an outer diameter correction method is applied is installed in an installation groove 17 having a tapered face 20 of which diameter is enlarged toward an injector body side (right side in the figure) to seal an annular clearance between an injector mounting hole and the injector 13. At the time of the outer diameter correction, a plurality of segments 24 of the outer diameter correction tool 23 are assembled to form the outer diameter correction tool on a side closer to the injector body than the combustion gas seal 22 with a state of surrounding the injector 3. The outer diameter correction tool 23 is moved on a tip side of the injector so that the outer diameter correction tool 23 is away from the injector body. By the movement, an outer diameter of the combustion gas seal 22 is corrected that was enlarged at the time of installation thereof into the installation groove 17.

摘要： PROBLEM TO BE SOLVED: To provide a fuel injection valve 10 absorbing an axial deviation between a fuel feeding pipe 1 and an assembling hole 4 without using a separate aligning ring as in the existing case.
SOLUTION: This fuel injection valve 10 separately includes: a fuel passage unit 11; a coil unit 30; and a lower housing 20. The existing contact support structure of the fuel injection valve with the aligning ring is formed between the fuel passage unit 11 and the lower housing 20. Thereby, since the fuel passage unit 11 is inclined in the lower housing 20, the axial deviation between the fuel feeding pipe 1 and the assembling hole 4 is absorbed inside of the fuel injection valve 10 without using the separate aligning ring as in the existing case.

摘要： PROBLEM TO BE SOLVED: To prevent falling off of a falling-off preventing ring 51 itself preventing falling off of a shaft displacement absorption washer 17 when a fuel injection valve 1 is fitted into the fitting hole 3 of an engine 2.
SOLUTION: The fuel injection valve 1 is pressurized with respect to the fitting hole 3, and pressurizing force is received by the shaft displacement absorption washer 17. The washer 17 is positioned in the inclined portion 12 of a large diameter portion, and a stage 25 having a washer receiving portion 26 exists between the large diameter hole portion 22 and intermediate diameter hole portion 21 of the fitting hole 3. The falling-off preventing ring 51 composed of a C-shaped ring is provided in a groove 50. The falling-off preventing ring 51 prevents falling off of the shaft displacement absorption washer 17 to the side of the engine 2. Dimensions D2, L1, and L3 are set such that when the falling-off preventing ring 51 itself falls off beyond a protuberance 53, the outermost diameter portion of the falling-off preventing ring 51 is prevented from falling off by being brought into contact with the inner peripheral wall of the fitting hole 3.

摘要： PROBLEM TO BE SOLVED: To provide a fuel injection valve which reduces changes of fuel injection characteristics when it is mounted on an engine. SOLUTION: An end 54 of a housing member 50, which forms a magnetic circuit on the side opposite to a holder, is not secured on a cylindrical member 11, so that the end 54 of the housing member 50 can be reciprocatingly moved relatively in the axial direction of the cylindrical member 11. Accordingly, when an injector 10 is mounted on the engine, even if the axial load acts on the housing member 50, deformation of the housing member 50 caused by the load is not transmitted to the cylindrical member 11. Consequently, before and after mounting the injector 10 on the engine, a change in distance between a fixed core 43 and a movable core 44 is reduced. Therefore, it is possible to reduce the changes of the fuel injection characteristics of the injector 10. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To improve the fuel injection characteristic and fuel sealing performance of fuel injection valves, facilitate their manufacture and reduce their manufacturing man-hour and cost. SOLUTION: A nozzle plate 61 has a smaller thickness at its cylinder portion 61b than at its bottom portion 61a, so that the cylinder portion 61b of reduced rigidity fitted on a valve body 26 prevents excessive compressive stresses on it irrespective of the inside diameter of nozzle holes 61d and keeps that internal wall of the valve body 26 which forms fuel passages 27a and 27b free of significant dimensional changes. This further keeps a guide portion 26a where a valve element 25a slides and a valve seat portion 26b where it is seated free of dimensional changes to thus improve the sliding motion of the valve element 25a or improve the fuel injection characteristic and the fuel sealing performance while the valve element 25a is inactivated. The dimensional design is easily obtainable from a single punching/drawing process of a uniform-thickness plate or from such a punching/drawing process plus succeeding drawing.
