摘要： PROBLEM TO BE SOLVED: To provide an injector in which even if a body is bent, a lateral load is not applied to a needle sliding portion not to cause impairment of a sliding property of the needle.
SOLUTION: The injector 1 is equipped with a needle 16 to which axial force in a valve opening direction is applied and a command piston 17 to which axial force in a valve closing direction is applied. An axial end of the needle 16 abuts against an axial end of the command piston 17. The end of the command piston 17 at a needle 16 side is supported by a lower body 11 in a freely slidable manner. Specifically, a spring seat 30 provided at the needle 16 side of the command piston 17 is in sliding contact with a spring housing chamber 37. As a result, even if a lower body 11 is bent, axile displacement of a needle abutting end X in the command piston 17 can be prevented, so that axial force only in the axial direction is applied to the abutting portion of the needle 16 and command piston 17, and therefore the lateral force is not applied to a needle sliding portion B, thus causing no impairment of the sliding property of the needle 16.

摘要翻译：要解决的问题：为了提供一种其中即使身体弯曲的注射器，也不会对针滑动部分施加横向负荷，而不会引起针的滑动性的损害。解决方案：喷射器1配备有向阀打开方向施加的轴向力的针16和施加阀闭合方向的轴向力的指令活塞17。针16的轴向端抵靠指令活塞17的轴向端。指针活塞17在针16侧的端部以可自由滑动的方式被下体11支撑。具体地说，设置在指针活塞17的针16侧的弹簧座30与弹簧容纳室37滑动接触。结果，即使下体11弯曲，针抵接端X的位置偏移可以防止指令活塞17，使得仅在轴向方向上的轴向力施加到针16和指令活塞17的抵接部分，因此横向力不施加到针滑动部分B，因此不产生针16的滑动性受损。版权所有（C）2008，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To reduce the likelihood that foreign matters are accumulated in a sliding gap between a valve body 16 and the sliding shaft 26 of an armature 24 to thereby impede sliding action in the electromagnetic valve 4 of an injector 1.SOLUTION: The valve body 16 includes a guide member 29 that is in sliding contact with the sliding shaft 26 of the armature 24 to support the sliding shaft 26 and a body 30 that is provided separately from the guide member 29 and integrated with the guide member 29 so as not to be in sliding contact with the sliding shaft 26. The guide member 29 is in sliding contact with the sliding shaft 26 at two separate positions including leading end side position and a rear end side position. A non-guide space 33 that does not allow the body 30 to be in sliding contact with the sliding shaft 26 is then formed between the leading end-side guide member 31 in sliding contact with the sliding shaft 26 on the leading end side and the rear end-side guide member 32 in sliding contact with the sliding shaft 26 on the rear end side. As a result, the likelihood can be reduced that the foreign matters are accumulated in the sliding gap between the valve body 16 and the sliding shaft 26 to thus impede sliding action.

摘要： PROBLEM TO BE SOLVED: To provide a fuel injection valve capable of suppressing the change in an injection characteristic due to temporal deterioration of a component.
SOLUTION: A fuel injection valve 10 includes a needle 51 for opening/closing an injection hole 22, a pressure control chamber 48 for accumulating fuel which biases the needle 51 in a valve closing direction and a control valve 12 for controlling the discharge amount of fuel accumulated in the pressure control chamber 48 to adjust fuel pressure in the pressure control chamber 48. A tip of the needle 51 and a tip of a control valve member 70 provided to the control valve 12 are formed so as to make an increasing/decreasing directions of seat areas thereof identical to each other with temporal deterioration. Even when the seat area of the needle 51 varies with the temporal deterioration to change valve opening pressure, the seat area of the control valve member 70 also varies in response to the changed valve opening pressure. Thus, the time to the injection rate rising timing from the supply start timing of drive current to a coil 83 provided to the control valve 12 can be made substantially identical.
