摘要： PURPOSE:To enable discharge of combustion gas, etc., generated in a mold through a passage from a gap of the abutting surface between the mold and a surface plate and to simply enable cleaning of the passage. CONSTITUTION:The surface plate 10 is the one used to a suction casting apparatus and a through-hole 10k for inserting a sprue pipe introducing a molten metal into the mold is formed at the center of the surface plate. Further, on this surface, a round recessed part 10r is concentrically formed at the position of the through-hole 10k, and the crosswised groove 10m is formed from this recessed part 10r to the outside of the mold laying surface. Therefore, at the time of laying the mold on the base board 10, the recessed part 10r and the groove 10m are covered by the lower surface of the mold to form the passage from the periphery of the through-hole 10k toward the outside of the mold. By this method, the combustion gas, etc., generated in the mold is discharged outside through this passage together with gas in a chamber. Further, as the passage is simply decomposed by taking off the mold from the surface plate 10, the cleaning is executed in every corners.

摘要： PROBLEM TO BE SOLVED: To provide a control valve for a liquid injection valve capable of quickly reducing pressure in a back pressure chamber and reducing ineffective injection time without enlarging an actuator in a liquid injection valve.
SOLUTION: Since opening and closing of the control valve are done by pushing and pulling a cylindrical valve element 24 in and out an upper space 22f of a cylindrical seat body 22, pressure of high pressure fuel does not act in the drive direction of the cylindrical valve element 24. Consequently, the cylindrical valve element 24 can be driven by small drive force and the actuator is not enlarged. When the valve is opened, an opening is formed over a whole circumference of a tip of the cylindrical seat body 22, a discharge channel of large opening area is formed in a short time even with a little axial separation, and a great quantity of high pressure fuel can be discharged in a short period of time. A tip surface of a piston 24b separates from a bottom wall 22b and an orifice 22g opens, and assist force is generated on the piston 24b. Consequently, ineffectual injection time can be reduced without enlarging the actuator, and response of the fuel injection valve can be increased.

摘要翻译：要解决的问题：提供一种能够快速降低背压室中的压力并减少无效喷射时间的液体喷射阀的控制阀，而不会增加液体喷射阀中的致动器。解决方案：由于控制阀的打开和关闭是通过将圆柱形阀元件24推入和拉出进入和离开圆柱形座椅主体22的上部空间22f而完成的，所以高压燃料的压力不会在驱动方向上作用因此，可以通过小的驱动力来驱动圆柱形阀元件24，并且致动器不被扩大。当阀打开时，在圆筒形座椅主体22的顶端的整个圆周上形成开口，即使在稍微轴向分离的情况下也在短时间内形成大开口面积的排出通道，并且大量高压力燃料可以在短时间内排出。活塞24b的尖端表面与底壁22b分离，并且孔口22g打开，并且在活塞24b上产生辅助力。因此，可以在不扩大执行器的情况下降低无效的喷射时间，并且可以提高燃料喷射阀的响应。版权所有（C）2010，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To improve the responsiveness of an armature when the armature is attracted toward an electromagnet and when the armature is separated from the electromagnet. SOLUTION: A housing 2 accommodates an armature 1, and an electromagnet 3 is attached to the housing 2 for exerting an attraction force on the armature 1. When the electromagnet 3 exerts the attraction force on the armature 1, the armature 1 abuts against an abutment portion 4. In order to improve the responsiveness exhibited when the armature 1 is attracted toward the electromagnet 3, a gap 5 between the armature 1 and the electromagnet 3 is preliminarily reduced before the electromagnet 3 starts exerting the attraction force on the armature 1. Further, in order to improve the responsiveness exhibited when the armature 1 is separated from the electromagnet 3, the gap 5 is preliminarily increased while the electromagnet 3 exerts the attraction force on the armature 1.
